ABSTRACT:
A central processing system can maintain an efficient information reading operation even when a program executed by a central processing unit contains many branch commands. A prefetch queue of the central processing unit reads and information expected to be processed next by the central processing unit from a main memory. The function of the prefetch queue is deactivated in accordance with a control signal provided from a prefetch queue control unit. A block transfer function of a cache memory is also deactivated when unnecessary information is read from the main memory in accordance with the block transfer function.
