EVS core components use code translation for speed. Not enabling Direct Memory Interface (DMI) reduces performance.
The core components in EVSs use code translation for high simulation speed. Therefore they fetch data from external memory to translate it into host machine code. Changing the memory contents outside of the scope of the core makes the data inconsistent.
Enable DMI accesses to instruction memory to avoid dramatic performance reductions. Otherwise, EVSs:
