Abstract
PURPOSE: To make sure of addresses that a program transits easily by adding at least one bit to data that correspond to each address and then by providing an additional memory in which a fixed level is written when access is attained.
CONSTITUTION: Adding CS part 11 is provided that adds one or a few bits to data which correspond to each address of control storage (CS) instruction part 3 of a microprocessor, and when a transit address is confirmed, the contents of adding CS part 11 that corresponds to each address are stored in transit address register 12 and then sent to transit address display part for display. When a transit address is only confirmed, one bit is added to each data and when a frequency in transit is also confirmed, a feedback circuit is provided between the input and output of adding CS part 11 by way of +1 arithmetic part 13 and the frequency is expressed by a few bits.
