2 Fetch-Decode-Execute Cycle The fetch-decode-execute cycle is the basic process of how the microprocessor executes instructions. It consists of three main steps: fetching, decoding, and executing.

A RISC-V processor has several defined decode spaces, for example custom0, custom1 etc. into which new custom instructions can be added. OVP Fast processor models can be extended without modification ...

In a single-cycle design, each instruction type—such as ALU operations, memory loads/stores, and control flow operations like jumps—must complete within a single clock cycle, regardless of its ...
