VGA 脱开功能为斯巴达

QFSK的调制与解调，用C写的主程序，汇编写的调制与解调的子程序(QFSK the modulation and demodulation, with the main program in C, compile writing, the modulation and demodulation of the Subprogram)

应用背景 可用于FIR滤波器的设计，移植性强。现在有代码是根据xilinx V4的硬件做的。可很方便的进行小的改动，去适应其它公司或版本的硬件IP核。不做改动也没问题。应该不用综合到IP core以外的逻辑中去。 关键技术 完全与xilinx的V4的DSP48硬件资料相同，比用IP generate产生的IPcore的好处就是可以随便换到其它芯片的代码中，甚至是altera的芯片中，也能编译通过。并且，对于乘法累加器不了解的筒子可以做个参考！

This VHDL code takes a clock, reset, Capture_EN and SPI data LT2315 ADC and generates SPI_CLK and SPI_nCS of it and reads 12-bit serial data ADC and returns 12-bit parallel data.

主控cc2530通过debug接口对目标cc2530进行程序烧写，使用DMA进行数据传输，已调试通过。(Master cc2530 through the debug interface for writing the program to target cc2530, using the DMA data transfer, has been work successful.)

VHDL的基本语法，应用，建模，编程示例等...(Introduction to VHDL basic syntax, applications, modeling, programming example and so on ...)

SystemVerilog 写的APB总线接口的uart 代码，带testbench.(Uart code of APB bus interface written by SystemVerilog, with testbench.)

控制8个发光二极管中的一个发光二极管发光，其它7个发光二极管都出于截止状态，发光二极管的导通顺序按照向左或向右两个方向移动，并且通过按键控制发光二极管循环发光移动的方向。(Control of a light-emitting diode light-emitting eight light-emitting diodes, the other seven light-emitting diodes for the cut-off state, light-emitting diode conduction order in accordance with the left or right move in both directions, and light-emitting diode cycle luminous button control mobile direction.)

基于查找表的DDS的Verilog实现，分为相位累加器模块、ROM模块和顶层DDS模块(Verilog implementation of DDS based on lookup table)

通过 ICAP 回读 FPGA内部state register 的状态值。通过状态机控制ICAP，然后写入命令，读取数据，等待三个周期后出现数据。过程中CSIB和RDWRB有一个时序关系，还需要对ICAP输入命令进行bit swap
