火车售票系统显示牌 FPGA VHDL

这个verilong代码实现的功能是radar processing的功能。(This verilong code function is radar processing functions.)

用Verilog描述了一款简单逻辑芯片74HC595的功能该芯片功能为：带输出锁存的8位移位寄存器(use the verilog to describe a simple chip 74HC595 with 8-Bit Serial-In, Parallel-Out Shift Reg and High-Current 3-State Outputs Reg)

说明：  5604FPGA驱动，能显示数字（5604里面为4个595）(5604 FPGA driver, able to display digital (5604 contains 4 595))

Verilog 我认为写的非常好的细节书(Verilog In my opinion written details of the book)

该代码实现了FPGA对USB芯片68013的读写，语言是VERLOD，试验通过。(The code to achieve the FPGA read and write 68013 on the USB chip, the language is VERLOD, through the test. )

用VERILOG编写的VGA字符显示，可以在电脑屏幕上显示字符,已通过测试(Prepared with the VERILOG VGA character display, can display characters on a computer screen, has been tested)

包含UART口的VERILOG源程序，该程序在FPGA上验证通过，可作为芯片设计，或FPGA设计的一个完整IP核，硬件设计的兄弟们可参考一下。-include UART port of VERILOG source, the program tested in FPGA, as chip design, or FPGA design of a complete IP cores, hardware design brothers can make reference.

fir低通滤波器 用于dspbuilder pll：25nss data 400khz sin 10.8khz 已通过测试。 (fir low pass filter for dspbuilder pll: 25nss data 400khz sin 10.8khz has been tested.)

logic lock 的vhdl源码，altera平台适用。-logic lock the VHDL source code, altera platform.

数字频率计VHDL程序 --文件名：plj.vhd。 --功能：频率计。具有4位显示，能自动根据7位十进制计数的结果，自动选择有效数据的 --高4位进行动态显示。小数点表示是千位，即KHz。-Digital Cymometer VHDL procedures- File name: plj.vhd.- Function: frequency meter. With four shows that will automatically count seven decimal results, automatic selection of effective data- four for the high dynamic display. Decimal point that is 1000, or KHz.
