Xilinx FPGA block RAM reconfig via JTAG

这是一段控制1394芯片的cpld的verilog程序,可以参考,在实际项目中已经采用.(This is a control chip cpld 1394 Verilog the procedures, they can refer to the actual project has been adopted.)

七段LED数码管显示译码器设计，将输入的16位二进制数据分别输出到4个数码管上(Seven-segment LED display decoder design, the input of 16 binary data are output to the four digital tube)

说明：  秒表的实现，有暂停清零功能，Quartus II(Stopwatch realization, has the pause clear function)

It is then register ( shifter) PISO ( Parallel - in, serial - out)-It is then register ( shifter) PISO ( Parallel- in, serial- out)

矩阵键盘控制的FPGA，verilog语言实现，包括rtl，ucf,以及testbench的详尽代码(Exhaustive code matrix keyboard control FPGA, Verilog language, including the rtl, ucf, and testbench)

简易函数发生器，能产生正弦波，三角波，梯形波，方波，并且可调频率和幅度值。(Simple function generator can produce sine, triangle wave, trapezoidal wave, square wave, and the adjustable frequency and amplitude values.)

详细讲述TURBO码的FPGA实现原理，可作参考，不是码源(A detailed account of the FPGA implementation of principle of the TURBO code can be used as reference, not source code)
