武汉工程大学电气信息学院张辉--NIOS II软核处理器在超声诊断中的应用
NIOS II软核处理器在超声诊断中的应用参赛院校:武汉工程大学电气信息学院参赛队员:张辉陆煊段国容指导教师:杨志方一,设计概述:当前的超声诊断系统，多以单片机为控制中心，或以单片机与 FPGA、CPLD 相结合的方式，研发人员在设计方案时，需要在选择单片机类型和规格上，花去不少宝贵的时间，在用单片机与 FPGA、CPLD 相结合的情况下，功能上又涉及到对它们的需求。
在相互匹配的过程中，不仅增加了开发周期，而且因为没法找到合理的匹配浪费了资源。
嵌入式系统发展朝着小体积、低功耗、高性能的趋势发展。
MCU、DSP和FPGA三种处理器在现代嵌入式系统中扮演的角色重现三分天下的局面，它们各自具有独特的优势而在某方面又略显不足。
以 51 系列单片机和ARM微处理器为代表的MCU家族因其丰富的软件支持在控制和处理人机接口领域占据绝对领先的地位；然而海量数据处理方面却被DSP占尽了风头；FPGA在高速复杂的逻辑处理方面独领风骚，并且最近异军突起，凭借其超大规模的单芯片容量和硬件电路的高速并行处理能力，在信号处理方面也显示出突出的优势。
因而，MCU、DSP、FPGA的结合将是未来嵌入式系统发展的趋势。
SOPC＝MCU＋DSP＋FPGA，SOPC可以将MCU、DSP和FPGA完美的结合。
NIOS II软核处理器的出现使SOPC的发展向前迈了一大步，在一片FPGA内可以嵌入一个或多个这样的处理器，设计者还可以根据自己的需要来调整嵌入式系统的特性、性能和成本，CPU和一些基本外设都可以在FPGA内实现，从根本上改变了计算机系统的拓扑结构，传统的CPU总线就从PCB上转移到FPGA内部，PCB变得非常简单。
FPGA内部总线可以很容易做到很高的速度，而且具有很大的灵活性。
同一块PCB，通过不同的FPGA配置，可以实现多种用途。
板卡调试过程几乎完全集中到FPGA内部，PCB可望一版成功，这就大大缩短了开放周期.超声诊断仪正朝着数字化、网络化方向发展，在存储量、处理速度和功耗上都提出越来越高的要求，而且要求易升级换代，更好的满足用户的需求。

近年提出的智能超表面时空编码方式拓展了超表面在物理维度上的自由度，使得其可以在单音波激励下完成多个频点的波束扫描，但仍然面临着增益低、波束副瓣大等一系列问题。
针对这些问题，提出了一种基于超表面的谐波波束扫描方法。
设计并加工了一种在Ｅ面可以达到斜入射６０°的角度不敏感２ｂｉｔ超表面单元并组建３２×３２阵列。
针对单元谐波状态做出精确的３ｂｉｔ相位量化。
通过针对不同的初始参考相位，使用多目标遗传算法进行优化，将正一阶谐波的波束副瓣压低在了－１５ｄＢ水平，完成了时空编码超表面在Ｅ面６０°波束扫描，为未来在超表面时空编码谐波波束赋形提供了充分有力的方案。

XR21B1420IL28-0A-EVB Evaluation Board User's Manua
XR21B1420IL28-0A-EVB Evaluation Board User’s ManualIntroductionThis user’s manual is for the XR21B1420IL24-0A-EVB evaluation board. The XR21B1420IL24-F shares a common evalua-tion board with the XR21B1421IL28-F and XR21B1421IL24-F . The main difference between the XR21B1420 and the XR21B1421 is that the XR21B1421 is an HID USB UART. The XR21B1420 is a USB CDC-ACM/Custom Vendor Request device. The only USB UART device installed on the XR21B1420IL24-0A-EVB evaluation board is the XR21B1420IL24-F .Evaluation Board OverviewA block diagram of the evaluation board is shown in Figure 1 below.Figure 1: Evaluation Board Block DiagramIn addition to the XR21B1420IL28-F , there is an Exar SP339 Multiprotocol transceiver on this evaluation board. The SP339can be configured for Loopback, RS-232, Half-Duplex RS-485 or Full-Duplex RS-485/422 Modes. The default setting when shipped from the factory is RS-232 mode.Figure 2 and Figure 3 on the next page show the top view and bottom view of the evaluation board with all of the compo-nents, connectors and headers labeled.Table 1: Evaluation Board Ordering Part Numbers Device Ordering Part Number Evaluation Board Ordering PartNumberDevice Package Device Location XR21B1421IL24-F XR21B1421IL24-0A-EVB24-pin QFN U3XR21B1421IL28-F XR21B1421IL28-0A-EVB28-pin QFN U5XR21B1420IL28-F XR21B1420IL28-0A-EVB 28-pin QFNU4Figure 2: Top View of Evaluation BoardFigure 3: Bottom View of Evaluation BoardHardware ConfigurationsThis sections describes the default settings when shipped from the factory and what jumper setting changes are required when changing modes.XR21B1420 Power ConfigurationsWhen shipped from the factory, the XR21B1420 is configured for bus-powered mode and uses the 5V from the USB VBUS pin. The default jumper settings are:Table 2: Default Jumper SettingsJ10 - 1 & 2Connects 5V from VBUS to VCC_REG (pin 7). A regulated 3.3V output will be availableon VCC (pin 6).J11Not installed.J13 - 2 & 3Connects all pull-up resistors to 3.3V (+VCC_OUT = +VCC).J19Not installed.If not using the 5V from VBUS, an external 3.3V can be supplied to the VCC_REG pin. For testing purposes, there is an Exar SP6260 regulator on board that can be used. The required jumper settings for 3.3V operation are as follows:Table 3: Jumper Settings for 3.3V OperationJ10 - 2 & 3Connects 3.3V from SP6260 to VCC_REG (pin 7). 3.3V will also need to be supplied toVCC via J19.J11Not installed.J13 - 2 & 3Connects all pull-up resistors to 3.3V (+VCC_OUT = +VCC).J19 - 1 & 2Connects the regulated 3.3V from the SP6260 to the VCC pin of the XR21B1420.GPIO ConfigurationsGPIO8/TXTWhen shipped from the factory, the GPIO8/TXT pin is connected to the LED. The default configuration of this pin is the TXT function.Table 4: Default Jumper Setting for GPIO8/TXTJ15 - 2 & 3GPIO8/TXT connected to LED D1. LED D1 toggles when data is transmitting.Changing the header to J15 1&2 and adding a jumper on J16 3&4 will allow the GPIO8/TXT pin to control the MODE1 pin of the SP338/SP339 transceiver.GPIO9/RXTWhen shipped from the factory, the GPIO9/RXT pin is connected to the LED. The default configuration of this pin is the RXT function.Table 5: Default Jumper Setting for GPIO9/RXTJ17 - 2 & 3GPIO9/RXT connected to LED D2. LED D2 toggles when data is received.Changing the header to J17 1&2 and adding a jumper on J16 5&6 will allow the GPIO5/RXT pin to control the MODE2 pin of the SP338 transceiver (this is a ’NC’ on the SP339).GPIO0/RI#/RWK#When shipped from the factory, the GPIO0/RI#/RWK# pin is connected to the push-button switch (SW1).Table 6: Default Jumper Setting for GPIO0/RI#/RWK#J12 - 1 & 2GPIO0/RI#/RWK# connected to SW1. Can be used for remote wake-up.Changing the header to J12 2&3 will connect the GPIO0/RI#/RWK# pin to the SP338/SP339 transceiver.GPIO2/DSR#By default, the GPIO2/DSR# pin is a GPIO input for the XR21B1420. When shipped from the factory, J20 is installed. The GPIO2/DSR# pin can be configured as a GPIO output using the GPIO control registers. See datasheet for complete details. SP338/SP339 Mode SelectionWhen shipped from the factory, the SP338/SP339 are configured in the RS-232 mode. This is achieved with a combination of J18 and J4.J18 pins 2, 4 and 6 go to MODE0, MODE1 and MODE2, respectively. The SP338/SP339 have weak internal pull-down resistors. Table7 shows the SP338/SP339 MODE pin configurations for the RS-232 mode.Table 7: SP339 RS-232 Mode ConfigurationsMODE01MODE10MODE20For the RS-232 mode, there is a jumper from J18 pin 2 to J4 pin 1. Refer to the table in the schematic or the SP339 data-sheet for more details of the different configurations.The SP338/339 transceiver is enabled with a jumper from J18 pin 8 to J4 pin 4.Half-duplex, Full-Duplex and Mixed Duplex RS-485/422 modesIn the RS-485 half-duplex, full-duplex and mixed duplex modes, the DIR1 pin of the SP338/SP339 enables or disables the RS-485/422 line drivers. The DIR1 pin can be controlled by the XR21B1420 using the G PIO3/RS485 or G PIO1/RTS#/ RS485 output pins. The GPIO7/RS845 or GPIO5/RTS#/RS485 pin can be selected via J21.Software and Technical SupportVisit /XR21B1420 or /XR21B1421 to download documentation and design tools including software, software drivers, evaluation board schematics, and evaluation board design files.
