vhdl code for 8051 processor

用来实现IRIG_B码的解码程序，在XILINX ISE上运行过没有问题，(Used to achieve IRIG_B code decoding process, in XILINX ISE run-off is no problem,)

说明：  该资料是用vhdl编写的按键消抖程序，按键消抖在使用按键的数字电路中非常重要，如果不对按键信号进行处理，有可能会出现大量错误的按键信号。文件key_xd.vhd是按键消抖程序，文件key_xd.vwf是仿真波形文件。该程序已经通过仿真测试，并且在电路板上调试通过，效果理想。(The information is written in the key consumer vhdl shaking procedures, key consumer shaking in digital circuits using the buttons is very important, if not key signal processing, there may be a lot of the wrong button signal. File key_xd.vhd is key consumer shake procedure is the simulation waveform file key_xd.vwf file. The program has been tested by simulation and debugging in circuit board by, the results are satisfactory.)

此源代码是基于Verilog语言的持续赋值方式定义的 2 选 1 多路选择器 、阻塞赋值方式定义的 2 选 1 多路选择器、非阻塞赋值、阻塞赋值、模为 60 的 BCD码加法计数器 、模为 60 的 BCD码加法计数器、BCD码—七段数码管显示译码器、用 casez 描述的数据选择器、隐含锁存器举例 ，特别是模为 60 的 BCD码加法计数器，这是我目前发现的最优源代码，应用于解码器领域。(This source code is based on the Verilog language define the continued assignment of 2-to-1 multiplexer, blocking assignments define the 2-to-1 multiplexer, non-blocking assignments, blocking assignments, module code for the addition of 60 BCD counters, BCD code module for the addition of 60 counters, BCD code- seven-segment LED display decoder, the data described by casez selector, for example hidden latch, in particular, the BCD model code for the addition of 60 counters, this is my found that the best current source code, the decoder used in the field.)

用verilog实现dsp与Fpga接口的同步设计，其功能包括读写操作及四个功能模块，采用两个fifo实现不同时钟域的地址与数据的转换，在quartus ii11.0环境下运行，运行此程序之前需运行将调用fifo。(Dsp using verilog achieve synchronization with Fpga interface design, its features include read and write operations and four functional modules, using two different clock domains to achieve fifo address and data conversion in quartus ii11.0 environment to run, run this program required before running calls fifo.)

说明：  VIVADO SOC 使用文档 基于zynq 7020(vivado soc example text of zynq)

利用FPGA，产生三相SPWM波，与后继硬件电路配合，形成三相电源。高效，实用。(Using FPGA, produce three-phase SPWM wave, with subsequent hardware circuit with the formation of three-phase power. Efficient and practical.)
