ram读写程序

说明：  URISC的RTL级设计，Verilog代码(Design: URISC RTL Verilog)

本代码实现16位数据的sin cos 计算，已经通过测试并且显示正确的波形图文件，仿真通过。在计算是很有帮助。本代码为原创代码，不同于流水线实现，而是以时间换取的面积。

说明：  Verilog简易教程，或者说是讲义，清晰易懂，适合初学者入门使用(Layman' s Guide to Verilog, or a lecture, legible entry to use for beginners)

描述发光耳机光的原理，而且可以调节二极管发光的时间，还有亮 的顺序。并通过实验版进行验证

FPGA上的一个半加器实例程序，通过测试，可以直接运行在fpga开发板上。(One and a half adder example on FPGA program, through the test, can be run directly on the FPGA development board)

Verilog reference book

说明：  单周期cpu，使用verilog编写的的单周期cpu支持......等功能(Single cycle CPU, using Verilog written single cycle CPU support... And other functions)

是用于pci开发的核，可以将硬件的信息映射到然间上来 节省出开发人员用于了解硬件的时间 (Pci developed for nuclear, hardware information can be mapped to the inter-ran up to save the developers time to understand the hardware)

The PID controller IP core performs digital proportional–integral–derivative controller (PID controller) algorithm. The algorithm first calculates the error between a measured value (PV) and its ideal value (SP), then use the error as an argument to calculate the manipulate value(MV). The MV will adjust the process to minimize the error. It can be used to calculate duty cycle for PWM (Pulse Width Modulation).
