Abstract

PURPOSE:To directly measure an instruction executing time without correcting a program, by measuring an instruction executing time to an address of the second external register from an address of the first external register. CONSTITUTION:As a program proceeds, when contents of a memory address register 2 coincide with a start address which has been set to the first external register 11, a counter 14 starts counting and counts a counting pulse. Subsequently, when contents of the register 2 coincide with a measurement stop address which has been set to the second external register 12, the counter 14 stops counting, holds a count value and displays it on a display mechanism 15. Since a clock of a data processing equipment is used for the counting pulse, a time from start of a measurement to stop is measured.
