Protected Functions Documentation

function IssuePendingFetchRequests

Issue pending fetch requests to instruction memory.

void simtix::pipelined::FetchStage::IssuePendingFetchRequests () 

Check for misaligned addresses, send fetch requests to the instruction memory, and handle access faults.

---

function ProcessReadyFetchRequests

Process fetch requests that are ready.

void simtix::pipelined::FetchStage::ProcessReadyFetchRequests () 

Process fetch requests that are in pending response. First check for address misalign and access fault. Then send the fetched instruction to the decode stage.
