MULTI PROCESSOR SYSTEM WHICH UTILIZES ENTIRE APPLICATION FUNCTIONS OF RESPECTIVE PROCESSORS, CAPABLE OF REDUCING SYSTEM IMPLEMENTING COSTS

摘要

PURPOSE: A multi processor system which utilizes entire application functions of respective processors is provided to largely improve system performance while reducing system implementing costs.;CONSTITUTION: Plural processors(100,200) include application processing function respectively. A multi port semiconductor memory device(410) includes a shared memory area(11) and an inner register. Through different ports, the shared memory area is accesses by the processors. The shared memory area is allocated to a memory cell array. The inner register provides access permission about the shared memory area to the processors. A non-volatile semiconductor memory device is connected with the processors.;COPYRIGHT KIPO 2010
