Designing a 5-Stage Pipelined RISC-V Processor from Scratch
A practical walkthrough of building an RV32I pipelined processor in SystemVerilog : from architecture to simulation, with forwarding, hazard detection, and a clear path to acceleration. RISC-V is an open instruction set architecture. That single fact changes what is possible…
