source: trunk/IPs/systemC/processor/Morpheo/Behavioural/Generic/RegisterFile/RegisterFile_Internal_Banked/src/RegisterFile_Internal_Banked_vhdl_body.cpp @ 145

Last change on this file since 145 was 145, checked in by rosiere, 15 years ago

1) add test with SPECINT2K
2) new config of Selftest
3) modif RAT to support multiple depth_save ... but not finish (need fix Update Prediction Table)
4) add Function_pointer but need fix
