Mitsubishi Electric Corp has developed a microprocessor simulator creation system which shows interactively the design status of the hardware and microprocessor, and has greatly improved debugging functions: a parallel processor and graphics functions can also be used for debugging and the project made use of a new operation description language Vegams-C; previously Vegams, a language based on Lisp jointly developed by Mitsubishi Electric’s Central Research Laboratories and its computer manufacturing plants was used, but the new C version gives a ten fold increase in speed, and has a demon feature that permits control of the inferencing strategy; it can also simulate other hardware; Mitsubishi Electric has already developed a simulator microprocessor for its industrial computers and hopes to produce a commercial version for its supermicros and workstations.
