Abstract
PURPOSE: To realize an economical constitution for the microprogram control with the flexibility maintained as in the case of formation of the microprogram.
CONSTITUTION: When order code (OP-C)10 among microorder words 1 is sent to decoder 60 via line 20, decoder 60 has an access. Thus decoder 60 delivers part of the control memory address to line 26 as well as delivers the control signals of arithmetic part 100 to line 22. Line 23 is part of the control signals delivered to line 22; line 24 is part of output line 20 of order code 10; and line 25 is the constant value signal determined by the hard wire code, i.e., the signal featuring the value of "0" or "1". Control memory address formation part (AGU) 70 produces the head address of the microprogram to the order via each signal supplied through lines 21, 23, 24 and 25 each and then delivers the head address to line 40 to give an access control to control memory 2.
