By prioritizing accessibility, organizations can demonstrate their commitment to inclusivity and ensure that all employees, visitors, and customers can enter and exit the premises with ease.In addition to security, traffic flow, and accessibility, the personnel entrance and exit system should also consider the needs of different user groups. For example, in a healthcare facility, there may bespecific requirements for patients, visitors, and staff, each with their own access needs and protocols. Similarly, in a corporate office, there may be separate entrance and exit points for employees, clients, and vendors. By tailoring the system to the unique needs of each user group, organizations can enhance the overall user experience and improve the efficiency of their operations.Furthermore, the personnel entrance and exit system should be designed with flexibility and adaptability in mind. As organizations evolve and their operational requirements change, the access control system should be able to accommodate these changes seamlessly. This may involve the integration of new technologies, the modification of existing protocols, or the reconfiguration of the physical layout of the access points. By maintaining a flexible and adaptable system, organizations can ensure that their personnel entrance and exit management remains effective and aligned with their evolving needs.Another important consideration in the design of personnel entrance and exit systems is the integration of data management and reporting capabilities. By collecting and analyzing data on the movement of people in and out of the premises, organizations can gain valuable insights into usage patterns, traffic flow, and potential security risks. This information can then be used to optimize the system, identify areas for improvement, and make informeddecisions about resource allocation and security protocols.Finally, the implementation of a personnel entrance and exit system should be accompanied by comprehensive training and communication efforts. It is essential that all relevant stakeholders, including employees, security personnel, and visitors, are well-informed about the protocols and procedures governing the access control system. This can be achieved through the development of clear and concise policies, the provision of training programs, and the implementation of effective signage and wayfinding systems. By ensuring that everyone understands and follows the established protocols, organizations can enhance the overall effectiveness of their personnel entrance and exit management.In conclusion, the design and implementation of an effective personnel entrance and exit system is a complex and multifaceted endeavor. It requires a careful consideration of various factors, including security, traffic flow, accessibility, user needs, flexibility, data management, and communication.

Structual Reform of APEC
Background InformationXISU MAPEC Open Structural Reform in APEC Region1.DefinitionStructural reform consists of improvements made to institutional frameworks, regulations and government policies so that the efficient functioning of markets is supported and behind-the-border barriers are reduced.Such work is expected to generate significant benefits and remains relevant for many current economic policy debates, including the issues related to the prospects of avoiding the middle income trap.2.Status QuoAPEC economies are facing an problem of slower global economic growth, slower potential growth, fiscal consolidation and relatively weak private sector investment. In such an environment, structural reforms are critical to boost the growth th rough increasing productivity and addressing APEC’s longer term development objectives of graduating to high income status and continuing improvements in living standards despite ageing populations in some economies.3.Current Achievements1.Since 2004, APEC’s structural reform agenda –through the Leaders’ Agenda to Implement Structural Reform (LAISR) and the subsequent APEC New Strategy for Structural Reform (ANSSR) has made a great contribution toreduce behind-the-border barriers and promote balanced, inclusive and sustainable growth in the region.2. At the second SRMM in Cebu, APEC economies welcomed the progress made in implementing structural reform under the ANSSR initiative launched in 2010. Ministers recognized the importance of● removing barriers;● identifying new sources of growth;● promoting innovation;● raising productivity;● narrowing development gaps;● steering the world economy towards a path of greater shared prosperity.In this regard, the agreement reached by APEC economies in 2015 to endorse the Renewed APEC Agenda for Structural Reform (RAASR 2016-2020) is a significant achievement.3. The Economic Committee has also carried out substantive work in regard to overcoming the Middle Income Trap through structural reform.In May 2015, the Committee held a seminar on the subject, with a second held in 2016. The committee points out that policies to promote innovation are an important means of escaping the Middle Income Trap, raising long-term productivity and creating inclusive and sustainable growth.4.Current ActivitiesIn 2016, EC(Economic Committee) supports APEC priorities by working on the implementation of the Renewed APEC Agenda for Structural Reform (RAASR) endorsed by the Structural Reform Ministerial Meeting (SRMM) held in Cebu, the Philippines in September 2015.RAASR aims to stimulate balanced and sustainable growth and reduce inequality.Key Initiatives:1.Inclusive growth/preparation of indicators under the RAASRpromote the use of quantitative indicators to measure APEC-wide progress on structural reform and supportan APEC structural reform progress report developed by the APEC Policy Support Unit (PSU)a policy framework in the area of structural reform and inclusive growththe APEC PSU report Assessing the APEC New Strategy for Structural Reform (ANSSR) was published2.Innovationan APEC Economic Policy Report (AEPR)the selection of Structural Reform and Innovation as the topic for the 2015 AEPR explored the links between structural reform and innovationinformation sharing with other relevant APEC fora on the policy issueswork on Middle Income Trap (MIT) issuesa further half-day seminar on MIT issues in the margins of the second Plenary meeting of the EC in August,2016.3.ServicesThe Committee is supporting the development of the APEC Services Cooperation Framework (ASCF) and is currently preparing the 2016 APEC Economic Policy Report, which will focus on Structural Reform and Services.develop an APEC Services Cooperation Framework (ASCF)closely collaborate with the Committee on Trade and Investment (CTI), the Group on Services (GoS) and other fora to:conduct public-private dialogues; conduct dialogues with sectoral regulators, policy makers, and business;andconsider developing a joint work program with GoS.Preparation of the 2016 APEC Economic Policy Report.4.Tools for structural reformIn 2015, the SRMM requested the EC encourage economies to increase their efforts to promote international regulatory cooperation, and to consider holding a Good Regulatory Practice Conference on the theme of building high-level support for reform (which includes international regulatory cooperation).5.Ease of Doing Business (EoDB)During the SRMM a second EoDB implementation plan was endorsed,of which are five priorities:starting a business; dealing with construction permits; trading across borders; getting credit; and enforcing contracts.draft and utilize the APEC EoDB Implementation Plan to guide capacity-buildingover the next three years.5.Three pillars of APEC Structural ReformIn 2015, APEC Ministers endorsed a Renewed APEC Agenda for Structural Reform (RAASR), which will guide APEC’s work on s tructural reform over the next five years until 2020.The RAASR aims for a robust, comprehensive and ambitious structural reform agenda to reduce inequality and stimulate growth in APEC economies, and contribute to APEC’s overarching goal to promote balanc ed, inclusive, sustainable, innovative and secure growth, through measures in line with the following three pillars:●more open, well-functioning, transparent and competitive markets;●deeper participation in those markets by all segments of society, inclu ding MSMEs, women, youth, older workers and people with disabilities;●sustainable social policies that promote the above mentioned objectives, enhance economic resiliency, and are well-targeted, effective and non-discriminatory.6.TerminologyBlue EconomyAs a kind of recycle economy,blue economy includes production activities for the development of ocean resources and ocean space,and direct or indirect services for the development of marine resources and space related industries. Compared with the traditional economic model and green economy,blue economy has four characteristics:Create jobs, create economic values, follow the ecosystem and zero emissions.It mainly focuses on coastal tourism,marine transportation,marine shipbuilding,marine fishery,marine high-tech industry and sea salt industry.Green EconomyThe green economy aims at reducing environmental risks and ecological scarcities, and it also aims for sustainable development without degrading the environment.It includes Open and competitive markets, Metrics, accounting, and reporting,Finance and investment,Awareness,Life cycle approach,Resource efficiency and decoupling, Employment,Education and skills,Governance and partnership,Integrated policy and decision-making.Solar energy,wind energy,tidal energy,environmentally friendly farming,low-carbon vehicles industry and IT industry are in the list of green economy.Middle Income TrapA country in the middle income trap will have lost their competitive edge in the exportation of manufactured goods because their wages are on a rising trend. However, they are unable to keep up with economically more developed economies in the high-value-added market. As a result, newly industrialised economies such as Brazil, the Philippines and Malaysia have not, for decades, left what the World Bank defines as the 'middle-income range' since their per capita gross national product has remained between $10,000 to $12,000 at constant prices. They suffer from low investment, slow growth in the secondary industry, limited industrial diversification and poor labor market conditions.LAISR（The Leaders’Agenda to Implement Structural Reform）Leaders’ Agenda to Implement Structural Reform (LAISR) is an agenda that the APEC Leaders reaffirm their political commitment made in Bangkok 2003 and demonstrate leadership to further promote structural reform in the APEC region.The APEC Leaders recognize the value of well-executed structural reform, underpinned by institutional capacity building, for achieving sustainable economic growth and supporting APEC’s goal of trade and investment liberalization.RAASR（Renewed APEC Agenda for Structural Reform）Renewed APEC Agenda for Structural Reform (RAASR)is set forth to provide a solid platform to meet the needs and priorities of APEC economies to 2020 and beyond. APEC economies invite Leaders to jointly pledge to undertake robust, comprehensive and ambitious structural reforms to reduce inequality and stimulate growth in their economies, and contribute to APEC’s overarching goal to promote balanced, inclusive, sustainable, innovative and secure growth.ANSSR(APEC New Strategy for Structural Reform )APEC New Strategy for Structural Reform(ANSSR) contributed significantly to market efficiencies through its emphasis on regulatory reform, strengthening economic and legal infrastructure, corporate governance, public sector governance, and competition policy.References1./Home/Groups/Economic-Committee2./~/media/Files/MinisterialStatements/Annual/2004/04_amm_02 0.pdf3./Documents/2011/SOM/SYM/11_som_sym1_002.doc4./Meeting-Papers/Sectoral-Ministerial-Meetings/Structural-Refo rm/2015_structural/Attachment%20A.aspx5.https:///wiki/Green_economy6.https:///wiki/The_Blue_Economy7.https:///wiki/Middle_income_trap。

Efficient Implementation of Precise Exception for Processor Based on Pre-detectionQingyu ChenXi‟an Microelectronics Technology InstituteXi‟an, Chinae-mail:**********************Longsheng WuXi‟an Microelectronics Technology InstituteXi‟an, Chinae-mail:**********************Erjuan ZhuShaanxi Changling Photovoltaic Electric Co. LtdBao ji, Chinae-mail:******************Abstract—Embedded systems have higher requirements on real-time performance of processor. However exception, which can interrupt normal execution of program, will decrease the processor performance. For improving the exception handling efficiency of processor, a precise exception handling method for embedded pipeline processor based on pre-detection is proposed in this paper. When the precise exception occurs in any pipeline stage, the precise exception flag is set valid immediately and advanced to the next pipeline stage. Based on pre-detection on the exception flag, a single-cycle NOP instruction is provided for the processor by a dedicated hardware module. That separates the processor from spending large number of clock cycles requesting main instruction memory for instructions which will be flushed in the process of exception handling. This method has been implemented in a SPARC V8 processor which has successfully taped out. Test results of chip show that the precise exception detection and response efficiency is increased by 35.47% without increasing the processor critical path. The proposed method can be used to improve response efficiency of the precise exception at low hardware overheads.Keywords-exception flag; pre-detection; dedicated module; NOP instruction; processorI.I NTRODUCTIONMost modern embedded processors develop the instruction-level parallelism and improve the real-time performance of processor by the means of deep pipeline and multiple issue[1]. These techniques make the control of the processor, especially the accurate control of exception more difficult. The implementation of the precise exception is the important to the processor to satisfy the sequential architecture [2].In order to implement the precise exception, the controller in the processor will flush all instructions in pipeline to ensure that the results of instruction execution will be committed in-order when it responses to precise exception. References [3-5] introduce some techniques, which are commonly used in out-of-order processor to implement the precise exception, and the authors had studied the implementation method of the hardware and the overhead, but did not consider the response efficiency of exception. And the implementation principles and schemes of precise exception in single issue processor are concluded in [6-9]. Those schemes can accelerate the speed of recovery processor context by increasing the backup buffer or future buffer, but they didn‟t take the time of fetching instruction into account as those instructions will be flushed finally in the response of exception.Aiming at the defects of the existing method for handling precise exception, this paper presents an optimization method to implement precise exception for single issue processor, and conducts an experimental verification with a SPARC V8 processor developed by Xi'an micro-electronics technology institute. The method focuses on reduce the time of fetching invalid instruction which is in the pipeline and have not arrived at write-back stage when processor is handling the precise exception. Firstly, the paper introduces the definition of precise exception and its implementation in SPARC V8 architecture, and then based on the analysis of the existing methods, the precise exception implementation method based on pre-detection are illustrated. Finally, we analyze and conclude the testing process and results of this method.II.P RECISE E XCEPTIONThe exception is like an unexpected procedure call and may be caused by an instruction-induced exception or an external interrupt request not directly related to a particular instruction. There are 256 distinct types of exception by 8-bit TT (trap type) field identification in SPARC V8 architecture —half for hardware exceptions and half for software exceptions and the transfer addresses of all traps are decided by the exceptional type. All exceptions can be divided into three categories of exception: precise exception, deferred exception or interrupting exception.A precise exception is induced by a particular instruction and occurs before any program-visible state has been changed by the trap-inducing instruction. Several conditions must hold: (1) The instructions before the one which induced the exception have completed execution.(2)The instructions after the one which induced the exception remain unexecuted. (3)The PC saved in local register1 points to the instruction which induced theInternational Conference on Mechatronics, Electronic, Industrial and Control Engineering (MEIC 2015)exception, and the NPC saved in local register2 points at the instruction which was to be executed next [10].III.I MPLEMENTATION OF P RECISE E XCEPTIONThe precise exception handling method based on pre-detection has been proved to be effective in a SPARC V8 processor which has been successfully taped out. The processor achieves 159 kinds of exceptions, of which 144 types of precise exceptions and 15 types of external interrupt which will induce deferred exceptions. This section mainly introduces the process of exception handle, the traditional method for implementing precise exception, and the method based on pre-detection which is proposed in this paper.A.Traditional ImplementationThe implementation of precise exception typically is divided into four processes. The first is the exception detection and response, namely detecting the exception in instructions, and beginning to handle. Secondly the context preservation, mainly refers to save instruction PC, processor state PSR, generate subroutine entry address of exception handler. And then the controller begins to execute exception handler programs. Finally recovering state/control fields, such as PSR, from exception handler subroutine, at the same time resuming the main program. The main process of exception handling and time consumption is shown in Fig .1. Different from the public methods which aim at decreasing t2 or t4, this paper focuses on optimizing t1 since the t1 time overhead is more serious than t2 and t4 in the deep pipeline processor.Figure 1.Process of exception handing & time consumptionThe V8 processor mentioned in this paper has a typical 5-stage pipeline, which are IF (instruction fetch), ID(instruction decode), EX(execute), MEM(memory access) and WB(write back). The traditional method to implement precise exception is shown in Fig .2, includingtwo steps: (1) distributional detection. In order to balance the payload of each pipeline stage, the detection andpriority arrangement of precise exception is distributed to the all pipeline stage. Ten kinds of exception related to instruction execution, such as illegal instruction, windows overflow, privileged instruction and floating exception, can be detected in ID stage and the highest priority exception is advanced to the EX stage after priority arrangement. Some precise exceptions which has relationship with memory accessing will be detected in MEM stage. (2) centralized control. All exceptions change the state of the processor in WB stage, which can simplify and reduce the degree of difficulty in achieving precise exception to put exception controller logic on WB stage. When finding the instruction exception in any pipeline stage except for WB stage, the pipeline controller executes it continually as a normal instruction instead of handling immediately and sets the exceptional flag and reason (TT) into pipeline registers to transfer it to the WB at the same time. As soon as the exception controller in WB detects the exceptional flags, it will generate exceptional service address according to exceptional reason (TT) and preserve the context of program execution. In addition, the exception controller will flush all instructions which are in pipeline at the same time. These flushed instruction execution will not change processor state, so these instructions are executed uselessly. We call these flushed instructions as invalid instruction. As is shown in Fig.2, there are four pipeline stages before WB stage. So, in the worst case, four invalid instructions would be in the pipeline. The operation on flushing these instructions will lead the time consumption in fetching invalid instructions useless. When instruction SUB induces an exception, which is shown in Fig .3, its subsequent instruction …AND‟, …XOR‟, …SMUL‟and …SDIV‟has been fetched and executed normally before the SUB reaching the WB. Exception controller will flush all instructions in the pipeline, …AND‟, …XOR‟, …SMUL‟and …SDIV‟in Fig.3, when the SUB arrives at the WB. Although the mechanism of central controller can simplify and reduce the implementation difficulty of precise exceptions, it cannot reduce the time consumption in instruction fetching and execution of invalid instruction.Figure 2.Traditional method to achieve precise exceptionclk_h addsub and xor smul sdive_trap⎪⎪⎪⎩⎪⎪⎪⎨⎧Figure 3. Instructions flush in the precise exceptionB. Implementation based on Pre-detectionIn order to reduce the time consumption of invalid instruction fetching, the method which is based on the mechanism of exception distributional detection, by pre-detecting the precise exception flags, immediately provides a single-cycle NOP instruction for the ID stage through a dedicated hardware module and stops IF stage to request instructions to slower main memory as soon as the EFD (exception flag detection) module finds the exceptional flags valid in any pipeline stage. The method can effectively reduce the time consumption of fetch instruction operation of the invalid instructions.The concrete implementation of this method is shown in Fig .4. When detecting the instruction exception in any pipeline stage, the exception flag is set valid in that pipeline stage. Two modules, namely EFD (exception flag detect) and ROR (read only register), are added in the IF stage of the processor. Considering the exception flagsthe output of the OR connects to EFD module. If the output of the OR is effective, EFD would ban processor to request instructions to the main memory through inull signal connected to the Icache (instruction cache) and select a NOP instruction saved in the ROR module for ID stage by a multi-channel selector. The exceptional flags will be valid until the instruction inducing exception is completely out of the pipeline where the EFD inull signal becoming invalid, IF resumes to request instructions to main memory and the processor is transferred to exception handler program to execute. Because invalid instructions replaced by NOP instruction which does not cause the change of processor state, The method can simplify the refresh logic for the whole pipeline with only refresh logic in EX and MEM stages retained. On the others hand, such a mechanism avoids the processor from spending plenty of clock cycles requesting instructions to slower main memory and reduces the time consumption of invalid instruction fetching.Figure 4. Implementation based on pre-detectionIV. V ERIFICATION AND R ESULTSThe exception response time of the processor is one of the important standards for the real-time performance. This scheme verifies the same two silicon circuits except for the method to implement precise exception on ASIC development board by the TIMER integrated into the processor[11]. The process and environment of testing are shown in Fig .5 and 6. In the process of testing, through the DSU we upload test case to SRAM with 5-waiting clock cycles in the GRMON environment and started running the processor[12]. When executing instruction ta1(soft trap), the processor enters debug mode. Then checking the TIMER count value, we can calculate the exception detection and response time t1 in specific test case according to the clock frequency. Test results are listed in the table 1 and 2 between different cases, of which case1 is suitable for illegal instruction exception, case2 for register file check error, case3 for unaligned address exception. case1, case2 and case3 are respectively detected in ID, EX and MEM stage. The verification results are catalogued in Table 1 and 2.Testing results show that: (1) when cache hit, this method has no effect on the precise exception responseefficiency. (2)When cache un-hit, the approach cansignificantly reduce the exception detection and response time t1. The earlier the exception flag is detected, the moreobvious this method optimizes the performance. The design implements 144 types of precise exception, of which 138 kinds are detected in ID stage, one kind is detected in EX stage, 5 types of precise exception are detected in MEM stage. With comprehensive consideration of various exception cases, the exception detection andFigure 5.Exception detect and response time testing processFigure 6.Silicon circuit verification environmentTABLE I.T ESTING R ESULT WITH C ACHE-UNHITTABLE II.T ESTING R ESULT WITH C ACHE-HITV.S UMMARYBased on the analysis on definition of SPARC V8 precision exception, this paper proposes a method to implement precise exception for single issue pipeline processor aiming at the deficiency of existing preciseexception implementation. When an exception occurs, the method, by pre-detecting the precise exception flags,immediately provides a single-cycle NOP instruction for the processor through a dedicated hardware module. Such a mechanism can effectively reduce the time consumption of fetch instruction operation of the invalid instructions and simplify the flush operation of the whole instruction pipeline. This method has been implemented in a SPARC V8 processors developed by Xi'an microelectronics technology institute. The exception detection and response time of the silicon circuit is verified through 6 cases. The results show that this method makes the precise exception detection and response time t1 reduced by 35.47%. The proposed method can be used to improve response efficiency of the precise exception at low hardware overheads.A CKNOWLEDGMENTThe research work is supported by National High-Tech Research and Development Program of China(No. 2010ZX01021, No. 2009ZX01023).

效率是公平的前提英语作文
效率是公平的前提英语作文Efficiency is the premise of fairness。
Efficiency and fairness are two fundamental principles that are often at odds with each other. On the one hand, efficiency focuses on achieving the best results in the shortest amount of time and with the least amount of resources. On the other hand, fairness emphasizes equal treatment and opportunities for all individuals. While it may seem difficult to reconcile these two principles, it is important to recognize that efficiency is the premise of fairness.First and foremost, efficiency is essential for creating a fair and just society. When resources are used efficiently, they can be distributed more equitably among the population. For example, in a healthcare system, efficient allocation of resources ensures that everyone has access to the care they need, regardless of their socioeconomic status. In contrast, a system that isinefficient and wasteful may result in unequal access to healthcare, with those who are less fortunate being left behind.Furthermore, efficiency is crucial for promoting economic growth and reducing poverty. When businesses and governments operate efficiently, they can generate more wealth and create more opportunities for individuals to improve their standard of living. This in turn leads to a more equitable distribution of resources and a reduction in income inequality. In contrast, inefficiency and corruption can lead to the concentration of wealth in the hands of a few, leaving the majority of the population in poverty.In addition, efficiency is important for ensuring that public services are delivered in a timely and effective manner. For example, efficient public transportation systems can provide equal access to mobility for all citizens, regardless of their income or social status. In contrast, inefficient and unreliable public services may disproportionately affect those who are already marginalized, further widening the gap between the havesand the have-nots.It is important to note that while efficiency is the premise of fairness, it is not sufficient on its own. Fairness also requires a commitment to justice, equality, and human rights. However, without efficiency, these principles may remain unfulfilled. Therefore, it is essential to strike a balance between efficiency and fairness in order to create a society that is both prosperous and just.In conclusion, efficiency is the premise of fairness. By promoting efficiency in the allocation of resources, the operation of businesses and governments, and the delivery of public services, we can create a more equitable and just society. However, it is important to recognize that efficiency alone is not enough, and that fairness also requires a commitment to justice, equality, and human rights. By striving for both efficiency and fairness, we can build a society that is not only prosperous, but also just and equitable for all.。

如何提高公共道德的英语作文
如何提高公共道德的英语作文Nowadays there are still many behaviors against public morality, such as spitting or littering in public, cutting in line. One of the main reasons for these is that some people lack personal manners and public consciousness. In addition , weak implementation of the administration measures contribute a lot to these uncivilized behaviors.Indeed , these small things in many people ‘s eyes have brought great bad effects . Above all , these immoral behaviors disturb social orders and disrupt soc ial stability. Moreover , one ‘s violating public morals not only invades others ‘ benefits but also does harm to himself. For example, if most people buy pirated products, those original producers might lose the enthusiasm to continue their producing.Taking the above-mentioned into consideration, I think, it is high time that we took effective measures to improve public morals . On one hand, we must use education to enhance their moral consciousness . On the other hand, the government should improve the administration system and ensure the efficient implementation of administration measures . In a word, the improvement of public morals depends on all of us.参考译文目前仍有许多违背公共道德的行为，如随地吐痰、在公共场所乱扔，插队。
