用VHDL写的一个显示程序，希望能帮上大家的忙，嘿嘿。

qpsk的fpga实现，包含调制和解调部分，使用verilog语言(FPGA implementation of QPSK)

说明：  基于蜂鸟E203riscv系统的DMA外设代码(DMA code based on hbird_e203 system)

verilog实现watch dog，可直接用于芯片开发中。(erilog realization watchdog, can be directly used for chip development.)

用vhdl编写的简易电子中设计，经过测试成功，且用记事本上载，无需阅读器进行阅读。-Use of VHDL in the preparation of simple electronic design, has been tested successfully, and use Notepad to upload without reader reading.

能够绘制数字电路的时序图，是fpga工程师时序设计和分析的神器(for digital circuit timming design and analysis)

可在FPGA上运行的8051 IP core,是学习FPGA及SPOC的好资料。-FPGA can be run on 8051 IP core, is to learn from FPGA and SPOC good information.
