Abstract

PURPOSE: To check the normalcy by reading the microorder address to be executed in the next cycle from the address storing circuit in each cycle and then inspecting the coincidence with the contents after replacement of the microorder address register.
CONSTITUTION: It is supposed that the branch conditions is set up in the B cycle in case the microprogram is carried out in the cycle of A→D. And with setting up of the branch conditions, the side of the branch address register 7 is selected at the selection circuit 9 and based on the flag information given from the deciding circuit 12, and the side of the branch setting address storing part 13 is selected by the selection circuit 15. As a result, the information e of the branch address register 7 is set to the microorder address register 2 in the E cycle after branching, and on the other hand the address information e read out of the storing part 13 is set at the address information register 5 respectively.
