A METHOD OF COMMUNICATING DATA BETWEEN THE CPU OF A HOST COMPUTER SYSTEM AND THE CPU OF A CO-PROCESSOR COMPUTER SYSTEM

摘要

A method of communicating data between the central processing unit (''CPU'') (12) of a host computer system (66) and the CPU (54) of a co-processor computer system (70) is provided for allowing noncompatible application software to be used by the host computer system. The method includes using a dual port random access memory (76) shared between the CPUs (12, 54) of the two computer systems for interprocessor communication.
