The fetch-decode-execute cycle is followed by a processor to process an instruction. The cycle consists of several stages. Depending on the type of instruction, additional steps may be taken: If the ...

The registers and key elements of the Von Neumann architecture all play a part in how an instruction is processed in the fetch-decode-execute cycle.

Instruction Fetch Phase: The program counter (PC) selects the next instruction from instruction memory. The PC is updated sequentially or modified by branch and jump logic. Instruction Decode Phase: ...

This project is a cycle-accurate implementation of the RISC-V (RV32I) Instruction Set Architecture based on a 5-stage pipeline (Fetch, Decode, Execute, Memory, and Writeback). Developed in Verilog HDL ...
