Abstract
PURPOSE: To increase a processing speed and to obtain flexible versatility, by setting the contents of an instruction register directly in an address register without through an instruction decoder.
CONSTITUTION: The memory of a microprogram storage device 15 is divided into pages each consisting of ≥2 words, and a page specifying register 51 controllable by a microprogram and an address specifying register 14 in a page into which the contents of an instruction register 11 are fetched directly are used to access the microprogram memory. Thus, an optional page is usable for decoding instructions.
