和picoblaze完全兼容的mcu ip core

通过一个计数器来实现输出信号的占空比要求，可以将duty_cycle分配到拨码开关上,LED分配到发光二极管上,然后调节拨码开关,即可看到LED的亮度发生变化.(The duty cycle of the output signal can be assigned to the dial switch by a counter, and the LED can be assigned to the light emitting diode. Then the brightness of the LED can be seen by adjusting the dial switch.)

modbus的fpga实现。opencores上最新版本。使用fpga实现，可以大大提高响应速度，对其功能进行模块化。(modbus of fpga implementation. opencores the latest version. Use fpga implementation, can greatly improve the response speed, its function modularity.)

SRAM读写测试，每秒进行一次单字节SRAM读写，使用chipscope观察时序波形(SRAM read and write test, a single byte SRAM read and write every second, using chipscope to observe the timing waveform)

用VHDL语言设计简单的CPU，重点设计微操作代码，然后设计CPU各组成模块，最后根据设计的微操作设计微指令，验证设计的正确性。可基本实现加、减、乘、除、移位、循环等操作。-VHDL language is designed to be simple to use the CPU, the focus of the design of micro-operation code, and then design the components of CPU module designed the final design of the micro-operation microinstruction to verify the correctness of the design. Can achieve the basic add, subtract, multiply, divide, transfer, recycling and other operations.

这是一本关于VHDL编程的书籍,网上突然发现的,相信对相关人员会有所用途.-This is a book on VHDL programming, on-line suddenly found, I believe that the relevant staff will be use.
