Filed: 1989-02-16
Abstract: PURPOSE:To accurately recognize the action state of a micro program by permitting a function model on a computer to agree with the action state of a real chip and learning the internal state of the chip which cannot directly be observed. CONSTITUTION:When CPU 1 accesses to a micro memory 2 and starts travelling, a signal conversion circuit 5 converts the actual input signal of CPU 1 into the input signal of the function model 6, gives it to the function model 6, converts the output signal and the internal signal of the function model 6 into actual signals of the circuit and gives them to a micro program execution control circuit (CTL) 7. CTL 7 inserts a wait cycle waiting for the execution of the micro program by CPU 1 and executes matching control in such a way that the action state of CPU 1 agrees with the action state of the function model 6. Consequently, the internal state of CPU 1 becomes identical with the function model 6 and it can be observed through the signal conversion circuit 5.
