RISC_CPU的设计不仅简化了指令系统，而且还通过简化指令系统使计算机的结构更加简单合理，从而提高了运算速度。本设计以硬件描述语言代码形式存在可与任何综合库、工艺库以及FPGA结合开发出用户需要的固核和硬核，可读性好，易于扩展使用。-RISC_CPU not only simplifies the design of instruction, but instruction by simplifying the structure of the computer is more simple and reasonable, thereby increasing processing speed. The design of the hardware descr iption language code to the form of existence can be integrated with any database, combined with FPGA technology library and user needs to develop solid-core and hard core, readable, and easy extensions.
