source: trunk/IPs/systemC/processor/Morpheo/Behavioural/Core/Multi_OOO_Engine/OOO_Engine/Commit_unit/src/Commit_unit_statistics_allocation.cpp @ 110

Last change on this file since 110 was 110, checked in by rosiere, 15 years ago

1) OOO_egine : add stat to depiste low perf source
2) Commit : add stat
3) LSU_Pointer : retire - always ack (else combinatory loop). insert - max nb_inst_memory
4) TopLevel? : add debug_idle_time to stop combinatory loop.
5) Issue_queue : add reexecute_queue, new implementation (routage after issue_queue)
6) Decod / Predictor : add "can_continue"
