LOADING/STORING FUNCTION UNIT OF MICROPROCESSOR AND APPARATUS FOR INFORMATION PROCESSING

摘要

PURPOSE: To perform plural load operations in parallel and to perform the store transfer operation by a super-scalar microprocessor provided with a load/ store function unit and a corresponding data cache. CONSTITUTION: A load/store function unit 134 includes plural entries RS0 to RS3 of a holding station 124, which are accessed in parallel and are coupled to a data cache 150 in parallel, and a store buffer circuit 180 having plural buffer entries SB0 to SB3. Store buffer entries are constituted so as to provide such first-in first-out buffer that the output from a lower-order entry of the buffer is given as the input to a higher-order entry.
