Abstract

PURPOSE: To obtain an economical microprogram controller, by using an excessive data part for a new microprogram word when the data width of a main memory device disagrees with the microprogram word.
CONSTITUTION: A microprogram has X-bit word length, the data of main memory part 1 has Y-bit word length, and an auxiliary microprogram has Z-bit word length. Address control part 5 assigns the microprogram of the main memory part and program words 10 and 11 are stored in register 101. program word part 102 is stored in register 104, and auxiliary program word part 103 is in auxiliary registers 105 to 107 assigned by program word X via control line 138. The auxiliary program stored is supplied to control part 3, where it is composed into microprogram words to control the microprogram.
