Abstract
PURPOSE: To make easy the analysis of cause due to failure in the microprogram or hardware, by detecting the branch of microprogram sequence and following easily the progress of execution of microprogram.
CONSTITUTION: The instruction executed is stored in the control memory 1, the address of instruction read out from the memory 1 is formed with the address forming circuit 6, the instruction read out from the memory 1 is fed to the operation circuit 5 via the instruction register 2 and the decoder 4, and the instruction read out is processed for operation. Further, the shunt address register 8 sequentially receiving the address of the circuit 6 and delivering the shunt address, and the address stack memory 10 receiving the output of the register 8 and the second instruction address and memorizing the shunt address according to the second address are provided, the substraction circuit 9 performs substraction between the both addresses. When the result of substraction is other than a given value, the second address is changed with the address stack pointer 11 and added to the memory 10, to display the content of the memory 10 at the address display section 15.
