说明：  Micron公司m73a系列nand flash仿真模型及测试文件(micron m73a series nand flash simulation model and testbench)

用于单片机的adc采集实验，经过降噪处理，结果精确(ADC acquisition experiment for single chip computer, after noise reduction processing, the result is accurate)

说明：  ADC Reference code!Clock 100kHz

一段很好地讲述PWM的VHDL硬件代码，可以在不同SOPC上运行实现

单片机4路ad模数转换数码管动态显示程序(4-way ad microcontroller analog to digital conversion digital tube dynamic display program)

基于PCI总线和LPC接口的POST主板诊断卡代码，已经通过fpga测试可以使用，性能非常稳定。(Based on the PCI bus and LPC POST motherboard diagnostic card code to interface fpga has passed the test can be used, the performance is very stable.)

说明：  是基于apb总线下的timer外设的rtl代码，主要包括apb_timer的master逻辑verilog，以及相应的开发文档，包括寄存器的描述，功能特性等。(RTL code is based on timer peripheral under APB bus, which mainly includes master logic Verilog of apb_timer and corresponding development documents, including the description of registers, functional characteristics and so on.)
