Abstract

PURPOSE: To make clear the input pattern that runs, by setting "1" to the memory bit corresponding to the address passed through and then reading out the buffer memory after execution of the program for regeneration of the address.
CONSTITUTION: At the time of on-line debug, central processor 1 sends the address to main memory 2 via address bus 4 for execution of the program. At that moment, program trace adaptor 3 receives the address like memory 2 and then sets the 1-bits buffer memory corresponding to the address. After collection of the debug data, the program address passed through is delivered to the input/output device to be connected to adaptor 3. Thus the debug operator can trace the program.
