4*4按键扫描电路

说明：  PL 和 PS 的高效交互是 zynq 7000 soc 开发的重中之重，常常需要将 PL 端的大量数据实时送到 PS 端处理，或者将 PS 端处理结果实时送到 PL 端处理，但是各种协议非常麻烦，灵活性也比较差，直接通过 AXI 总线来读写 PS 端 ddr 的数据，这里面涉及到 AXI4 协议，vivado 的 FPGA 调试等。(The efficient interaction between PL and PS is the top priority of zynq 7000 SoC development. We often need to send a large amount of data from PL to PS for real-time processing, or send the processing results from PS to pl for real-time processing. In general, we will think of using DMA for processing, but various protocols are very troublesome and the flexibility is poor. This course explains how to use Axi directly Bus to read and write DDR data of PS terminal, which involves axi4 protocol, FPGA debugging of vivado, etc.)

可在FPGA上运行的8051 IP core,是学习FPGA及SPOC的好资料。-FPGA can be run on 8051 IP core, is to learn from FPGA and SPOC good information.

说明：  本文详细描述了SSI协议的通讯格式、原理及应用电路,并采用verilog语言实现了SSI通讯协议.设计实用电路并实现了与绝对值编码器的通讯(SSI protocol described in detail the communication format, principle and application circuit, and use verilog language of the SSI protocol. Practical circuit design and implementation of the communication with the absolute encoder)

说明：  Vivado是Xilinx最新的FPGA设计工具，支持7系列以后的FPGA及Zynq 7000的开发。与之前的ISE设计套件相比，Vivado可以说是全新设计的。无论从界面、设置、算法，还是从对使用者思路的要求，都是全新的。看在Vivado上，Tcl已经成为唯一支持的脚本，此文件是vivado是tcl命令的集合。(Vivado is Xilinx's latest FPGA design tool that supports development of FPGAs and Zynq 7000s in the 7 series and beyond. Compared with the previous ISE design suite, Vivado can be said that the new design. No matter from the interface, settings, algorithms, or from the user ideas, are new. Look at Vivado, Tcl has become the only supported script, this file is vivado tcl command collection.)

说明：  该程序包是SD卡/MMC卡控制器SDC的verilog语言包，它包括以下4部分：RTL源代码，测试平台，软件仿真文件，说明文件。(This source package is the SD card and MMC card controler model based on the Verilog language. It has the following 4 parts: RTL language, testbench, software simulating files and help document.)

一个具有“百分秒，秒，分”计时功能的数字跑表，可以实现一个小时以内的精确至百分之一秒的计时。 数字跑表的显示读者可以通过编写数码管显示程序来实现，本训练只给出数字跑表的实现过程。 读者还可以通过增加小时的计时功能，实现完整的跑表功能。(A " percentage of seconds, seconds, minutes," digital stopwatch timer can be achieved within an hour of precision to the hundredth of a second time. Digital stopwatch readers can display the digital display through the preparation of procedures to achieve, given the training is only the realization of the process of digital stopwatch. Readers can also function to increase hours of time to achieve full stopwatch function.)

关于i2c master/slaver control 方面的技术资料 介绍其特色与使用方法(On the i2c master/slaver control of technical information on their characteristics and use)

用verilog实现的UDP协议，包括arp，udp，ip分段协议等，对于想用FPGA实现TCP/IP协议的人来说，应该会起到一定的帮助作用(Implemented with verilog UDP protocols, including arp, udp, ip fragmentation protocol, etc., who want to achieve TCP/IP protocol with the FPGA people, should play a helpful role)
