CPU
运用vhdl硬件描述语言在quartus II开发环境下独立设计与实现了基于精简指令集的五级流水线CPU的设计与实现。该流水CPU包括：取指模块，译码模块，执行模块，访存模块，写回模块，寄存器组模块，控制相关检测模块，Forwarding模块。该CPU在TEC-CA实验平台上运行，并且通过Debugcontroller软件进行单步调试，实验表明，该流水线CPU消除了控制相关、数据相关和结构相关。(Using vhdl hardware description language development environment under quartus II design and implementation of an independent design and implementation of a five-stage pipeline RISC-based CPU' s. The water CPU include: fetch module, decoding module, execution modules, memory access module, the write-back module, the register set of modules, control relevant to the detection module, Forwarding module. The CPU in the TEC-CA experimental platforms, and single-step debugging through Debugcontroller software, experiments show that the pipelined CPU eliminates the control-related, data-related and structurally related.)
