Abstract
PURPOSE: To realize a high-performance control for the microprogram by recording the variable length microorder word in plural units on one line and thus increasing the memory capacity for the microorder memory unit.
CONSTITUTION: Microorder memory unit 10 stores plural units of the variable length microorder word composed of an optional integer-fold length as much as the basic unit length, and the variable length microorder word to be executed is selected from unit 10 via order setting circuit 20. Then the output of circuit 10 is accumulated in control register 30, and the fixed pattern is generated via default pattern generation circuit 50 at the fields other than the variable length of register 30. The next address of unit 10 is grown based on the output of test circuit 70 which detects the state of unit 60, and at the same time circuit 20 is controlled by address generation circuit 110. In this way, the memory capacity of unit 10 can be increased, ensuring a high-performance control for the microprogram.
