The Xilinx Zynq-7000 Extensible Processing Platform (EPP) redefines the possibilities for embedded systems, giving system and software architects and developers a flexible platform to launch their NEW solutions and traditional ASIC and ASSP users an alternative that aligns with today’s programmable imperative. The NEW class of product elegantly combines an industrystandard ARMprocessor-based system with Xilinx 28nm programmable logic—in a single device. The processor boots first, prior to configuration of the programmable logic. This, along with a streamlined workflow, saves time and effort and lets software developers and hardware designers start development simultaneously.

I2C總線器件在高抗干擾系統中的應用: 摘要:本文先對I2C總線協議進行了簡要敘述,然后介紹了一些常用的抗干擾措施,最后提供了一個利用I2C總線器件24WC01組成的高抗干擾應用方案。 一、I2C總線概述 I2C總線是一雙線串行總線,它提供一小型網絡系統為總線上的電路共享公共的總線。總線上的器件有單片機LCD驅動器以及E2PROM器等。型號有:PCF8566T、SAA1064T、24WC01等。 兩根雙向線中,一根是串行數據線(SDA),另一根是串行時鐘線(SCL)。總線和器件間的數據傳送均由這根線完成。每一個器件都有一個唯一的地址,以區別總線上的其它器件。當執行數據傳送時,誰是主器件,誰是從器件詳見表1。主器件是啟動數據發送并產生時鐘信號的器件。被尋址的任何器件都可看作從器件。I2C總線是多主機總線,意思是可以兩個或更多的能夠控制總線的器件與總線連接。

這個軟件需要你的本機操作的。其他機器是算不出來的! 就是說 一臺電腦只有一個注冊碼對應! 這里有個辦法: MULTISIM2001安裝方法: 一:運行SETUP.EXE安裝。在安裝時,要重新啟動計算機一次。 二:啟動后在“開始>程序”中找到STARTUP項,運行后,繼續進行安裝,安裝過程中,第一次要求輸入“CODE"碼時, 輸入“PP-0411-48015-7464-32084"輸入后,會提示"VALID SERIAL NUMBER FOR MULTISIM 2001 POWER-PRO." 按確定,又會出現一個“feature code”框,輸入“FC-6424-04180-0044-13881”后, 在彈出的對話框中選擇“取消”,一路確定即可完成安裝。 三:1.運行VERILOG目錄內的SETUP安裝 2.運行FPGA目錄內的SETUP安裝 3.將CRACK目錄內的LICMGR.DLL拷貝到WINDOWS系統的SYSTEM 目錄內 4.并將VERILOG安裝目錄內的同名文件刪除 5.將SILOS.LIC文件拷到VERILOG安裝目錄內覆蓋原文件,并作如下編輯: 6.將“COMPUTER_NAME”替換為你的機器名 7.將“D:\MULTISIM\VERILOG\PATH_TO_SIMUCAD.EXE”替換為你的 實際安裝路徑。如此你便可以使用VERILOG了。 四:安裝之后,運行MULTISIM2001,會要求輸入“RELEASE CODE",不用著急, 記下“SERIAL NUMBER"和“SIGNATURE NUMBER", 使用CRACK目錄內的注冊器“MULTISIM KEYGEN.EXE" 將剛才記下的兩個號碼分別填入后, 即可得到"RELEASE CODE", 以后就可以正常使用了。 五:接下來運行 database update目錄中的幾個文件, 進行數據庫合并即可。祝你成功!! 六:啟動MULTISIM2001時候的注冊碼 1: PP-0411-48015-7464-32084 2: 37506-86380 3:的三個空格 1975 2711 4842 里面包含了:Multisim2001漢化破解版、Multisim.V10.0.1.漢化破解版圖解 解壓密碼:www.pp51.com

Abstract: As industrial control systems (ICSs) have become increasingly connected and use more off-the-shelfcomponents, NEW vulnerabilities to cyber attacks have emerged. This tutorial looks at three types of ICSs:programmable logic controllers (PLCs), supervisory control and data acquisition (SCADA) systems, anddistributed control systems (DCSs), and then discusses security issues and remedies. This document alsoexplains the benefits and limitations of two cryptographic solutions (digital signatures and encryption) andelaborates on the reasons for using security ICs in an ICS to support cryptography.

Frequently, voltage reference stability and noise defi nemeasurement limits in instrumentation systems. In particular,reference noise often sets stable resolution limits.Reference voltages have decreased with the continuingdrop in system power supply voltages, making referencenoise increasingly important. The compressed signalprocessing range mandates a commensurate reductionin reference noise to maintain resolution. Noise ultimatelytranslates into quantization uncertainty in A to D converters,introducing jitter in applications such as scales, inertialnavigation systems, infrared thermography, DVMs andmedical imaging apparatus. A NEW low voltage reference,the LTC6655, has only 0.3ppm (775nV) noise at 2.5VOUT.Figure 1 lists salient specifi cations in tabular form. Accuracyand temperature coeffi cient are characteristic ofhigh grade, low voltage references. 0.1Hz to 10Hz noise,particularly noteworthy, is unequalled by any low voltageelectronic reference.
