A 5-Stage Pipelined RISC-V Processor designed and implemented on FPGA (Artix-7 Nexys A7). Supports RV32I instructions set (R, I, S, B, U, J types) with ALU, control unit, hazard detection, forwarding, and pipeline registers. Verified through simulation and hardware testing with optimized timing and ×ばつ performance gain.
