Abstract

PURPOSE:To know an address to be set by an address search by enabling to record all addresses of a main storage device wherein data is stored by a program. CONSTITUTION:As a program runs, a CPU2 assigns an address via an address line 8 and transmits and receives information between a main storage device MMU1 and the CPU2 via a data line 7. Instructions the CPU executes during the said period are inputted to a store instruction detector 3 via a signal line 9. The detector 3 checks the input and, when it is a store instruction, cntrols a recording device 5 to set to ''1'' the bit of an address memory 4 specified by an address on the address line 8 at this time. Thus, address of data written in the MMU1 are all indicated by ''1'' in the address memory 4, so the storage of the memory 4 is used to debug a program.
