FIG. 1 is a diagram showing an embodiment of this invention, FIG. 2 is a diagram showing a measurement procedure in this invention, FIG. 3 is a diagram showing a measuring device that measures the internal state of a conventional computer system, and FIG. The figure is a diagram showing a measurement procedure in a measurement device that measures an internal state in a conventional computer system. In the figure, 1 is the main memory of the computer, 2 is measured data whose internal state is measured, 3 is a measurement data change command to change the measured data 2, 4 is a measurement program for measuring the internal state, 5 is a measurement device that is controlled by the measurement program 4 and measures the internal state; 6 is a memory address that displays the address of the data being changed; 7 is the next instruction to be changed after the measurement data change instruction 3; 8 is a measurement device that measures the internal state; A measurement request command to start a measurement program 4; 9 a search address register that stores an address in the main memory where data is stored as a measurement address; 10 an address specified by the search address register; An address match detecting section 11 generates an address match interrupt when a memory address matches an address indicated by the memory address, and 11 is an address match interrupt response address that is changed when an address match interrupt occurs. Note that the same reference numerals in each figure indicate the same or corresponding parts.
