INFORMATION PROCESSING SYSTEM

WIPO Patent Application WO/1981/001892

A1

An information processing system (10) including an arithmetic unit (13) in which an item of data is processed according to one instruction, another arithmetic unit (14) in which plural items of data are processed according to one instruction, an instruction control unit (15) for distributing corresponding instruction groups to respective ones of the arithmetic units (13, 14), and a main memory (12) for exchanging data with the instruction control unit (15) and with both arithmetic units (13, 14). In the information processing system (10), a group of instructions among the above-mentioned groups of instructions, which group is restricted by the order of priority as to the execution sequence thereof, is synchronized by specially inserting a synchronization instruction (WAIT). It is also possible to divide the above-mentioned groups of instructions into a group of instructions to be serial-processed and a group of instructions capable of being parallel-processed, as to the execution sequence thereof, by inserting a serialization-start instruction (POST) and a serialization-release instruction (SUB - WAIT).
