Multiprocessor system

Abstract

Abstract A multiprocessor system includes a co-processor (2) that executes operations instructed by a main processor (1) using one or more internal registers incorporated therein. The co-processor comprises a mode display means indicating one of a first mode and a second mode in accordance with one of a first request and a second request selectively given from said main processor; and an initialisation control means which does not initialise said one or more internal registers when said mode display means indicates said first mode at the time of completion of each of said operations, and initialises said one or more internal registers when said mode display means indicates said second mode at the time of completion of each of said operations.
