Abstract
PURPOSE: To prevent programs from becoming uncontrolled by detecting a fault of branch operation in its early stage by the method, which discriminates whether or not the branch destination of a microprogram reaches its correct address within a certain time, provided to a controller.
CONSTITUTION: The controller which reads out and executes microprograms in control memory unit 1 sequentially is provided with microprogram control part 4 determining addresses in controller 1 and micro-instruction register 2 holding instructions read out from controller 1. In addition, present address register 5 is provided which holds the program address equivalent to an instruction under execution at that time, and microprogram execution part 3 is also provided which executes instructions in register 5. Further, this controller is also equipped with correct-address register 6 which holds a correct branch-destination address by the instruction of an instruction, and coincidence circuit 7 which detects the coincidence between registers 5 and 6. Then, FF8 which detects an error detection signal by receiving the instruction and the output of circuit 7, and error detection circuit 9 are provided
