Debugging and analysis method by comparison of access state of memory

摘要

PURPOSE: To improve efficiency for debugging and analyzing a program by storing program areas executed on different conditions in first an second memories, comparing the respective program areas and extracting the program area stored in the second memory. ;CONSTITUTION: By extracting two pieces of address information of different conditions from a target memory 1, where the program to be the object of debugging is stored, and switching a switching circuit 2 for a memory bank, first, this address information is stored in an access state recording memory 3 and next, it is recorded in an access state recording memory 4. Afterwards, the respective contents of the recording memories 3 and 4 are compared by a recording memory comparison program 5 and corresponding to the compared result 6, the program area related to only a specified system operation is extracted. Thus, only the program area related to only the uncertified specified system can be easily extracted from the entire program, and debugging and analysis can be easily performed in a short time.;COPYRIGHT: (C)1996,JPO
