Abstract
PURPOSE: To grasp the program execution sequence and to simplify the inquiry for the factor of the fault occurrence in the computer which performs the arithmetic control based on the program by providing the trace bit at the control program area.
CONSTITUTION: The computer contains arithmetic process part 1, program counter part 2 to indicate the operation execution sequence, memory part 4 possessing address part 3 which is indicated by part 2, and decoder part 5 to give the arithmetic process information to part 1 respectively. In such computer, trace bit 21 is provided at the program area of part 4, and output part 22 is connected to bit 21. Furthermore, one bit correspondint to part 3 is given to bit 21. And when the fixed memory of part 4 is supplied to decoder part 9 via the designated address of part 3 corresponding to the contents of part 2, bit 21 also transfers the data to part 22. And this output is used as the trigger signal in order to memorize the contents of counter 2.
