Temperature-Controlled Refresh ModeDuring normal operation, temperature-controlled refresh (TCR) mode disabled, the de-vice must have a REFRESH command issued once every t REFI, except for what is al-lowed by posting (see REFRESH Command section). This means a REFRESH command must be issued once every 7.8μs if T C is less than or equal to 85°C, once every 3.9μs if T C is greater than 85°C, once every 1.95μs if T C is greater than 95°C, regardless of which Temperature Mode is selected (MR4[2]). TCR mode is disabled by setting MR4[3] = 0while TCR mode is enabled by setting MR4[3] = 1. When TCR mode is enabled (MR4[3]= 1), the Temperature Mode must be selected where MR4[2] = 0 enables the Normal Temperature Mode while MR4[2] = 1 enables the Extended Temperature Mode.When TCR mode is enabled, the device will register the externally supplied REFRESH command and adjust the internal refresh period to be longer than t REFI of the normal temperature range, when allowed, by skipping REFRESH commands with the proper gear ratio. TCR mode has two Temperature Modes to select between the normal tem-perature range and the extended temperature range; the correct Temperature Mode must be selected so the internal control operates correctly. The DRAM must have the correct refresh rate applied externally; the internal refresh rate is determined by the DRAM based upon the temperature.Normal Temperature ModeREFRESH commands should be issued to the device with the refresh period equal to t REFI of normal temperature range (-40°C to 85°C). The system must guarantee that the T C does not exceed 85°C when t REFI of the normal temperature range is used. The de-vice may adjust the internal refresh period to be longer than t REFI of the normal tem-perature range by skipping external REFRESH commands with the proper gear ratio when T C is below 85°C. The internal refresh period is automatically adjusted inside the DRAM, and the DRAM controller does not need to provide any additional control.Extended Temperature ModeREFRESH commands should be issued to the device with the refresh period equal to t REFI of extended temperature range (85°C to 95°C, or 95°C to 105°C) . The system must guarantee that the T C does not exceed 95°C, or 105°C. Even though the external refresh supports the extended temperature range, the device may adjust its internal refresh pe-riod to be equal to or longer than t REFI of the normal temperature range (-40°C to 85°C)by skipping external REFRESH commands with the proper gear ratio when T C is equal to or below 85°C. The internal refresh period is automatically adjusted inside the DRAM, and the DRAM controller does not need to provide any additional control.Table 49: Normal t REFI Refresh (TCR Enabled)8Gb: x4, x8, x16 DDR4 SDRAM Temperature-Controlled Refresh ModeRAS lockout circuit feature allows the PRECHARGE operation to be partially or com-pletely hidden during burst READ cycles when the auto precharge feature is engaged.The PRECHARGE operation will not begin until after the last data of the burst write se-quence is properly stored in the memory array.REFRESH CommandThe REFRESH command (REF) is used during normal operation of the device. This command is nonpersistent, so it must be issued each time a refresh is required. The de-vice requires REFRESH cycles at an average periodic interval of t REFI. When CS_n,RAS_n/A16, and CAS_n/A15 are held LOW and WE_n/A14 HIGH at the rising edge of the clock, the device enters a REFRESH cycle. All banks of the SDRAM must be pre-charged and idle for a minimum of the precharge time, t RP (MIN), before the REFRESH command can be applied. The refresh addressing is generated by the internal DRAM re-fresh controller. This makes the address bits “Don’t Care” during a REFRESH command.An internal address counter supplies the addresses during the REFRESH cycle. No con-trol of the external address bus is required once this cycle has started. When the RE-FRESH cycle has completed, all banks of the SDRAM will be in the precharged (idle)state. A delay between the REFRESH command and the next valid command, except DES, must be greater than or equal to the minimum REFRESH cycle time t RFC (MIN),as shown in Figure 84 (page 147).Note: The t RFC timing parameter depends on memory density.In general, a REFRESH command needs to be issued to the device regularly every t REFI interval. To allow for improved efficiency in scheduling and switching between tasks,some flexibility in the absolute refresh interval is provided for postponing and pulling-in the REFRESH command. A limited number REFRESH commands can be postponed depending on refresh mode: a maximum of 8 REFRESH commands can be postponed when the device is in 1X refresh mode; a maximum of 16 REFRESH commands can be postponed when the device is in 2X refresh mode; and a maximum of 32 REFRESH commands can be postponed when the device is in 4X refresh mode.When 8 consecutive REFRESH commands are postponed, the resulting maximum inter-val between the surrounding REFRESH commands is limited to 9 × t REFI (see Figure 85(page 147)). For both the 2X and 4X refresh modes, the maximum interval between sur-rounding REFRESH commands allowed is limited to 17 × t REFI2 and 33 × t REFI4, re-spectively.A limited number REFRESH commands can be pulled-in as well. A maximum of 8 addi-tional REFRESH commands can be issued in advance or “pulled-in” in 1X refresh mode,a maximum of 16 additional REFRESH commands can be issued when in advance in 2X refresh mode, and a maximum of 32 additional REFRESH commands can be issued in advance when in 4X refresh mode. Each of these REFRESH commands reduces the number of regular REFRESH commands required later by one. The resulting maximum interval between two surrounding REFRESH commands is limited to 9 × t REFI (Fig-ure 86 (page 147)), 17 × t RFEI2, or 33 × t REFI4. At any given time, a maximum of 16 REF commands can be issued within 2 × t REFI, 32 REF2 commands can be issued within 4 ×t REFI2, and 64 REF4 commands can be issued within 8 × t REFI4 (larger densities are limited by tRFC1, tRFC2, and tRFC4, respectively, which must still be met).8Gb: x4, x8, x16 DDR4 SDRAM REFRESH CommandFigure 84: REFRESH Command TimingCK_tCK_cCommand Don’t CareNotes: 1.Only DES commands are allowed after a REFRESH command is registered until t RFC(MIN) expires.2.Time interval between two REFRESH commands may be extended to a maximum of 9 ×t REFI.Figure 85: Postponing REFRESH Commands (Example)WFigure 86: Pulling In REFRESH Commands (Example)W8 REF-Commands pulled-in8Gb: x4, x8, x16 DDR4 SDRAM REFRESH Command。

ni4882 ibdev函数详解

ni4882 ibdev函数详解ni4882是一种在测试和测量设备中用于进行通信的标准接口，它是IEEE-488（通常称为GPIB）总线的一部分。

在GPIB总线上，设备可以使用一组命令进行通信，其中包括读写数据、查询设备状态等操作。

而在进行这些通信操作时，开发人员可以使用IB（Instrument Control）库来调用一系列的函数来完成操作。

其中，ibdev函数是用来建立与GPIB设备通信连接的函数。

本文将详细解释ibdev函数的用法及其参数含义。

1. ibdev函数概述ibdev函数是GPIB通信中用来打开设备连接的函数，它的原型如下所示：int ibdev(int boardID, int pad, int sad, int timeout, int send_eoi, int eos_mode)其中，各参数的含义分别是：- boardID：GPIB控制器的板号，对应不同的GPIB控制器- pad：设备位置区域，在GPIB总线上，每个设备都有一个唯一的位置区域- sad：辅助位置区域，有些设备具有两个位置区域，sad用来指定设备的第二个位置区域- timeout：超时时间，超过这个时间没有通信则会返回错误- send_eoi：表示是否在发送最后一个数据字节后自动发送结束信号- eos_mode：结束符模式，用于设定接收到何种字符时停止接收数据2. ibdev函数的使用方法在使用ibdev函数之前，首先需要通过ibfind函数找到GPIB控制器的位置区域。

然后才可以使用ibdev函数建立与设备的连接。

以下是一个简单的使用示例：#include <gpib.h>// 打开与GPIB设备连接int dev = ibdev(boardID, pad, sad, timeout, send_eoi,eos_mode);if (dev < 0) {// 连接失败} else {// 连接成功}在示例代码中，首先通过gpib.h头文件引入了GPIB通信相关的函数和数据类型，然后使用ibdev函数打开了与GPIB设备的连接。

第三次作业带有GPIB接口的芯片TNT4882

TNT4882芯片名称：TNT4882生厂商：美国NI公司芯片功能：TNT4882是美国NI公司的一款单芯片、高速、听/讲功能的兼备的GPIB 接口专用芯片。

它内部集成了Turbo488 （高速传输电路）以及NAT4882（IEEE4 88.2兼容电路），并拥有诸多新的特性，能够兼容ANSI IEEE Standard 488.1和ANSI IEEE Standard 488.2规范，因而可以为GPIB系统提供一套完整的解决方案。

为了达到更高的传输速率。

TNT4882采用了单芯片FIFO缓存电路设计，其内置的16个增强型IEEE 488.1兼容收发器可以直接连接GPIB总线，以实现HS488传输模式（一种新的GPIB高速传输模式）。

在兼容性方面，它与以往使用的“PD7216 TMS9914A 中的寄存器设置完全兼容，用户可以将以前所用的代码直接移植到TNT4882上。

同时，它所包含的Turbo488电路及其诸多新特性也可以在一定程度上减少软件的开销。

另外，TMT4882还具有灵活的CPU 接口，可以方便地连接各种16位或8位微处理器，并将CPU发出的消息和信号转化成相应的GPIB消息和信号，以使实现GPIB设备和CPU及内存之间的通信。

GPIB （General Purpose Interface Bus）接口总线最早由美国HP公司倡导实施，命名为HPIB。

由于它良好的接口特性，很快在国际范围内得到广泛的应用，并被美国电气与电子工程学会命名为IEEE488,在英国和日本等国家则称为GPIB。

虽然有多种叫法，但实际上除了机械标准有所不同外，其实质完全相同。

For complete register descriptions, see the “TNT4882Programmer Reference Manual” (320724-01)2. Some of the 7210 mode registers, such as the ISR1, havethe same names as some of the 9914 mode registers. The7210 mode registers are NOT the same as their 9914 modecounterparts. Be sure to refer to the appropriate bit map forthe chip emulation mode you are using when programmingthese registers.3. The shaded registers are “paged-in registers.” Paged-inregisters only exist in 9914 mode. Writing to the address of the9914 mode ADSR normally does not access any registers.Writing one of four page-in commands to the AUXCR changesall subsequent writes to that address to that of the corresponding paged-in register . The two readable paged-in registers, the 9914 mode SPSR and ISR2, are both paged in whenever any one of the four writable paged-in registers is paged in. When you write the clear page-in command to the AUXCR, all paged-in registers are paged out again and are no longer accessible.4.There are several unused bytes in the address space of the TNT4882. These addresses are reserved for adding new features to the chip. You should not map any external hardware into these addresses or access them at any time, as this may cause compatibility problems with future versions of the TNT4882.TNT4882 Single-Chip IEEE 488.2 Talker/Listener ASICNational Instruments Phone: (512) 794-0100 • Fax: (512) 683-9300 • info@ • 7zero; leaving them unconnectedcauses those address lines to becompared to one.
