用verilog HDL编写的SPI控制器，从国外网站上找到的。-SPI (Serial Peripheral Interface) is serial, synchronous, full duplex communication protocol. It is widely used as a board-level interface between different devices such as microcontrollers, DACs, ADCs and others.

数字信号除了的FPGA实现的Verilog源代码，之前发过一份是VHDL，各有所需吧，需要的看看吧(Digital signal in addition to the realization of the FPGA Verilog source code, send before a is VHDL, each have need it, need to look at it )

自己编写的一个verilog HDL小程序，实现基本的task调用function的功能，对初学者有用。在xilinx的ISE仿真调试通过(I have written a verilog HDL small procedures, to achieve the basic function of the task to call the function, useful for beginners. In Xilinx s ISE simulation debugging through)
