📑 About

A RISC-like, five-stages pipeline processor implemented using Verilog ,It is based on the Reduced Instruction Set Computer (RISC) architecture, The five stages of the pipeline include instruction fetch, instruction decode, execution, memory access and write back. Each stage takes a single clock cycle to complete and the instructions are executed in parallel. This allows for faster execution of instructions compared to other architectures. Verilog is used to implement the processor.
