标准SDR SDRAM控制器参考设计，Lattice提供的verilog源代码

程序主要是用硬件描述语言（VHDL）实现： 4*4键盘扫描，简洁明了，通俗易懂，比较适合VHDL初学者-procedure was used in hardware description language (VHDL) to achieve : 4* 4 keyboard scan, concise, easily understood and more suitable for beginners VHDL

基于FPGA的正弦脉宽调制波vhdl代码，同时输出正弦波与SPWM(Sine pulse width modulation wave VHDL code based on FPGA, at the same time with SPWM output sine wave)

说明：  verilog 编写的ldpc编码，含有两个文件(LDPC written by Verilog)

此代码是SPI接口的Master的Verilog源代码，经上板测试是没有问题的，请大家放心使用 (This code SPI Interface Master of Verilog source code, there is no problem on board test, please rest assured to use)

the transmitter and receiver modules for serial communication

很不错的资源哦，这是我在实验室当年总结的关于nios timer的程序段(nios timer)

ML605评估板上的流水灯，可以实现每隔0.16秒进行+1操作 #include #include #include #include #include int main() {   char a[] = "-100" ;   char b[] = "123" ;   int c ;   c = atoi( a ) + atoi( b ) ;   printf("c = %d ", c) ;   return 0;

主要给出准循环的LDPC码编码实现方法，译码方法选择，并给出了帧同步的解决方法(Give the main quasi-cyclic LDPC codes achieve coding method, decoding method of selection, and give the frame synchronization solution)

VHDL数字系统设计和工程实践2，包含原理，真值表和原理图，以及VHDL源代码.-VHDL digital system design and engineering practice, one that contains principles, truth table and schematic, as well as VHDL source code.
