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。 关键词：Verilog HDL；硬件描述语言；FPGA Abstract: In this ...

研究一种基于TMS320F28335 DSP（Digital Signal Processor）的全数字飞行器控制系统的硬件设计，分析了其结构组成：主控制器电路、舵面位置检测电路和通讯等硬件电路设计。经过多次试验调试，所设计的硬件系统可以满足飞行器性能要求。 ...

　　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 ...

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 ...

  The data plane of the reference design consists of a configurable multi-channel XBERT modulethat generates and checks high-speed serial data transmitted and received by the MGTs. Eachchannel in the XBERT module consists of two MGTs (MGTA and MGTB), which physicallyoccupy one MGT tile in t ...

  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) ...

  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 ...

ARM通讯 　　H-JTAG 是一款简单易用的的调试代理软件，功能和流行的MULTI-ICE 类似。H-JTAG 包括两个工具软件：H-JTAG SERVER 和H-FLASHER。其中，H-JTAG SERVER 实现调试代理的功能，而H-FLASHER则实现了FLASH 烧写的功能。H-JTAG 的基本结构如下图1-1所示。　　H-JTAG支持所有基于ARM7 和ARM9的芯片的调试，并且支持大 ...
