source: trunk/IPs/systemC/processor/Morpheo/Behavioural/Core/Multi_Execute_loop/Execute_loop/Multi_Write_unit/Write_unit/Execute_queue/src/Execute_queue_vhdl_declaration.cpp @ 98

Last change on this file since 98 was 98, checked in by rosiere, 15 years ago

1) Fix bug (read unit, RAT -> write in R0, SPR desallocation ...)
2) Change VHDL Execute_queue -> use Generic/Queue?
3) Complete document on VHDL generation
4) Add soc test
