Abstract
PURPOSE:To minimize the time required for exchange of information between processors by securing the free accesses of a main processor to all registers set into a co-processor. CONSTITUTION:A main processor 1 contains an address bus 11 and an information bus 12 and processes the information on a processing system. A co-processor 2 exclusively takes charge of the host arithmetic processing and contains a CPU 21 and a memory 22. The CPU 21 includes an accumulator 211, a stack memory 212, a program counter 213 which stores the address of the instruction to be executed next, and another register 214. An address bus 23 and an information bus 24 are connected to the co-processor 2. Thus the processor 1 can freely have accesses to all registers via the buffers 13 and 14. In such a constitution, the information transfer time is minimized between processors and the information can be easily processed.
