ABSTRACT:
A system for measuring program execution time compares all addresses occurring on a memory bus to an upper limit number and a lower limit number to produce a signal which indicates if each address occurring on the memory bus is within a range represented by the upper limit number and the lower limit number. The signal is utilized to either enable incrementing of a counter at a predetermined rate or to increment the counter once for every new address occurring on the memory bus within the range. The contents of the counter represent either the accumulated time of execution of instructions having addresses within the range or the number of instructions executed having addresses within the range. The system includes a display for displaying the contents of the counter.
