Abstract

PURPOSE: To compress the size of a control memory unit, etc., which store instruction words and enlarge a field designating an extension function by designating data stored in a register file as source data without increment of word length of the micro instruction words.
CONSTITUTION: Source data is stored in A register 20 to E register 24 and register file 25, and field S of the micro instruction word having designation code information of registers 20W24 and address information of file 25 is connected directly to registers 20W24 and file 25 through selector switch 26. Field EXT deisgnating the extension function of the instruction word is connected to selector switch 27; and in case that registers 20W24 are deisgnated as file data, source data is supplied to switch 27 through switch 26; and in case that file 25 is designated as source data, contents of file 25 are supplied to switch 27. Then, contents of registers 20W24 or file 25 are compressed and outputted according to designation of field EXT by switch 27.
