Abstract

PURPOSE:To execute a change of a retry state simultaneously, by utilizing a micro- instruction for a branch test of an outlet and an inlet of a loop. CONSTITUTION:Test fields T1, T2 and a test function field T3 are provided on a micro-instruction register 1. This register 1 is connected to a control memory device through a signal line 9, and is connected to a decoder 5, a test matrix 2, a test matrix 3 and an operator 4 through signal lines 10, 11, 12 and 13, respectively. Outputs of these decoder 5, test matrixes 2, 3 and operator 4 are coupled with a retry status discriminating circuit 6. In case it is desired to change a retry state at an outlet or an inlet of the loop part of a microprogram, an output of the discriminating circuit 6 is made to pass through a retry status display latch 7 by utilizing a micro-instruction for a branch test, and a retry signal is applied to a retry control device.
