可编程逻辑 WP328-FPGA的语音数据融合
 
The SDI standards are the predominant standards for uncompressed digital videointerfaces in the broadcast studio and video production center. The first SDI standard,SD-SDI, allowed standard-definition digital video to be transported over the coaxial cableinfrastructure initially instal ...
可编程逻辑 Creating Safe State Machines(Mentor)
 
Finite state machines are widely used in digital circuit designs. Generally, when designing a state machine using an HDL, the synthesis tools will optimize away all states that cannot be reached and generate a highly optimized circuit. Sometimes, however, the optimization is not acceptabl ...
可编程逻辑 基于CPLD的QDPSK调制解调电路设计
为了在CDMA系统中更好地应用QDPSK数字调制方式，在分析四相相对移相（QDPSK)信号调制解调原理的基础上，设计了一种QDPSK调制解调电路，它包括串并转换、差分编码、四相载波产生和选相、相干解调、差分译码和并串转换电路。在MAX+PLUSⅡ软件平台上，进行了编译和波形仿真。综合后下载到复杂可编程逻辑器件EPM7128SLC84-15中 ...
可编程逻辑 基于Verilog HDL设计的多功能数字钟
本文利用Verilog HDL 语言自顶向下的设计方法设计多功能数字钟，突出了其作为硬件描述语言的良好的可读性、可移植性和易理解等优点，并通过Altera QuartusⅡ 4.1 和ModelSim SE 6.0 完成综合、仿真。此程序通过下载到FPGA 芯片后，可应用于实际的数字钟显示中。

工控技术 赛灵思电机控制开发套件简介（英文版）
The power of programmability gives industrial automation designers a highly efficient， cost-effective alternative to traditional motor control units （MCUs）。 The parallel-processing power， fast computational speeds， and connectivity versatility of Xilinx® FPGAs can accelerate the impl ...
工控技术 工业系统安全问题和解决办法
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 (SCA ...
测试测量 HDMI一致性测试
 
The high defi nition multimedia interface (HDMI) is fastbecoming the de facto standard for passing digitalaudio and video data in home entertainment systems.This standard includes an I2C type bus called a displaydata channel (DDC) that is used to pass extended digitalinterface data (EDID) ...
测试测量 LT5528 WCDMA ACPR和AltCPR测量
 
ACPR (adjacent channel power ratio), AltCPR (alternatechannel power ratio), and noise are important performancemetrics for digital communication systems thatuse, for example, WCDMA (wideband code division multipleaccess) modulation. ACPR and AltCPR are bothmeasures of spectral regrowth. T ...
