Abstract

PURPOSE:To speed up the interpretation of instruction code and the access to the control memory at branch operation, by giving the instruction word fetched in advance to the instruction word buffer and providing the branched instruction code register every half length of the word. CONSTITUTION:The instruction word buffer 1 fetches and stores the continuous instruction words of a plurality. On the other hand, the branched instruction code register A41 and the branched code register B42 are provided every a half word. Thus, the interpretation of instruction code and access to the control memory at branch operation can be made in high speed.
