Vhdl实现计算exp功能 在apex20k上经过验证

SRAM的读写代码，对SRAM进行了乒乓操作，用VHDL语言进行设计，很有参考价值，甚至可以直接复制代码来进行自己的设计(SRAM read and write code, ping-pong operation carried out on the SRAM, using VHDL language design, of great reference value, or even directly copy the code to carry out their own designs)

比较实用的ps2键盘源码 可以在SOPC中进行添加组件 以实现自己所需的功能-Comparison of practical ps2 keyboard source code can be carried out in the SOPC components add to the functionality required to realize their own

this example finds the gapes that are existed in a word

基于PCF8591数模转换和DDS技术的信号发生器系统设计(Design of Signal Generator System Based on PCF8591 Digital-to-Analog Conversion and DDS Technology)

本程序是用VHDL语言实现电子密码锁功能,整个系统分为三大模块,一为控制模块,二为键盘显示模块,三为处理模块-This procedure is a VHDL language electronic code lock function, the entire system is divided into three modules, one for the control module, two for the keyboard display module, three modules for the treatment

此程序基于ADC0809,它是CMOS的8位A/D转换器，片内有8路模拟开关，可控制8个模拟量中的一个进入转换器中。-Connection between ADC 0809, it was the eight CMOS A/D converters. Tablets containing eight analog switches, control eight of analog converters enter a Chinese.

圖形介面乘法器,也可自行使用verilog去改(Graphical interface multiplier, also free to use verilog go and change)

rs422标准通讯模块 异步收发 verilog语言编写(rs422 standard communication module asynchronous receiver verilog language)

tdma参数化模块。可以自动生成2的n次的tdma哥时隙，用户可根据需要自己配置参数(tdma see the number of model lumps. 2 n basis following manner tdma chance possible 以自 dynamic generation, for root needed self-placement see number)

说明：  adc器件ads62p49配置代码，已在工程中验证可用(Temperature sensor DS18B20 parses the code, has verified the ADC device configuration code, has been verified available)
