source: trunk/IPs/systemC/processor/Morpheo/Behavioural/src/Vhdl_std_logic.cpp @ 95

Last change on this file since 95 was 95, checked in by rosiere, 16 years ago

1) Update Prediction Table - New architecture (systemC) done (and tested) -> need change interface in top level
2) Change documentation on VHDL generation
3) Change VHDL constant (case std_logic and std_logic_vector)
