The Virtex™-4 user access register (USR_ACCESS_VIRTEX4) is a 32-bit register thatprovides direct access to bitstream data by the FPGA fabric. It is useful for loadingPowerPC™ 405 (PPC405) processor caches and/or other data into the FPGA after the FPGAhas been configured, thus achieving partial reconfiguration. The USR_ACCESS_VIRTEX4register is programmed through the bitstream with a command that writes a series of 32-bitwords.

XAPP520將符合2.5V和3.3V I/O標準的7系列FPGA高性能I/O Bank進行連接 The I/Os in Xilinx® 7 series FPGAs are classified as either high range (HR) or high performance (HP) banks. HR I/O banks can be operated from 1.2V to 3.3V, whereas HP I/O banks are optimized for operation between 1.2V and 1.8V. In circumstances that require an HP 1.8V I/O bank to interface with 2.5V or 3.3V logic, a range of options can be deployed. This application note describes methodologies for interfacing 7 series HP I/O banks with 2.5V and 3.3V systems

Abstract: Many modern industrial, medical, and commercial applications require temperature measurements in the extended temperature rangewith accuracies of ±0.3°C or better, performed with reasonable cost and often with low power consumption. This article explains how platinumresistance temperature detectors (PRTDs) can perform measurements over wide temperature ranges of -200°C to +850°C, with absolute accuracyand repeatability better than ±0.3°C, when used with modern processors capable of resolving nonlinear mathematical equation quickly and costeffectively. This article is the second installment of a series on PRTDs. For the first installment, please read application note 4875, "High-Accuracy Temperature Measurements Call for Platinum Resistance Temperature Detectors (PRTDs) and Precision Delta-Sigma ADCs."

Automobiles, aircraft, marine vehicles, uninterruptiblepower supplies and telecom hardware represent areasutilizing series connected battery stacks. These stacksof individual cells may contain many units, reaching potentialsof hundreds of volts. In such systems it is oftendesirable to accurately determine each individual cell’svoltage. Obtaining this information in the presence of thehigh “common mode” voltage generated by the batterystack is more diffi cult than might be supposed.

仿真步驟如下： 1、把3個帖子的內(nèi)容分別保存為51t9py.c,51t9py_indexa.h,5py_mb.h，放在同一目錄下，將51t9py.c加入工程編譯 2、由于Keil的模擬串口是單字節(jié)顯示，漢字顯示為亂碼，所以要加掛RICHWIN或RichView這種會重新刷新顯示的中文平臺，或手工刷新屏幕，所以請先到 http://www.pchome.net/dl/chinese.htm 下載RichView，安裝運行 3、在Keil環(huán)境下可以直接按“Ctrl＋F5”鍵仿真，按“F5”全速運行，切換到在串口依次輸入: // 64*.6 426***.5 98*.7 936.3 586.1 4826*.1 9464*.7 64*.6試試:-) 4、按鍵對應(根據(jù)我自己的手機設置的,全部在PC的小鍵盤操作)：
