Member Data Documentation

bool Minor::Fetch1::Fetch1ThreadInfo::blocked

Blocked indication for report.

Definition at line 275 of file fetch1.hh.

Referenced by Minor::Fetch1::minorTrace().

TheISA::PCState Minor::Fetch1::Fetch1ThreadInfo::pc

Fetch PC value.

This is updated by branches from Execute, branch prediction targets from Fetch2 and by incrementing it as we fetch lines subsequent to those two sources.

Definition at line 261 of file fetch1.hh.

Referenced by Minor::Fetch1::changeStream(), Minor::Fetch1::fetchLine(), and Minor::Fetch1::wakeupFetch().

InstSeqNum Minor::Fetch1::Fetch1ThreadInfo::predictionSeqNum

Prediction sequence number.

This changes when requests from Execute or Fetch2 ask for a change of fetch address and is used to tag lines by the prediction to which they belong. Fetch2 originates prediction sequence numbers.

Definition at line 272 of file fetch1.hh.

Referenced by Minor::Fetch1::fetchLine(), Minor::Fetch1::FetchRequest::isDiscardable(), and Minor::Fetch1::updateExpectedSeqNums().

FetchState Minor::Fetch1::Fetch1ThreadInfo::state

Referenced by Minor::Fetch1::changeStream(), Minor::Fetch1::evaluate(), Minor::Fetch1::isDrained(), Minor::Fetch1::minorTrace(), Minor::Fetch1::processResponse(), and Minor::Fetch1::wakeupFetch().

InstSeqNum Minor::Fetch1::Fetch1ThreadInfo::streamSeqNum

Stream sequence number.

This changes on request from Execute and is used to tag instructions by the fetch stream to which they belong. Execute originates new prediction sequence numbers.

Referenced by Minor::Fetch1::evaluate(), Minor::Fetch1::fetchLine(), Minor::Fetch1::FetchRequest::isDiscardable(), Minor::Fetch1::minorTrace(), and Minor::Fetch1::updateExpectedSeqNums().

bool Minor::Fetch1::Fetch1ThreadInfo::wakeupGuard

Signal to guard against sleeping first cycle of wakeup.
