Title:
METHOD FOR CONFIRMING PROGRAM EXECUTION STATE
Document Type and Number:
Japanese Patent JP3140262
Kind Code:
B2
Abstract:

PURPOSE: To easily confirm and observe the operation state of a program and to improve the reliability of the program by displaying the level of analog signal generated based on numeric data corresponding to the respective blocks constituting the program on the time base of a display means.
CONSTITUTION: A CPU 11 executes an interruption processing program with an interruption signal sent periodically at a period T. The interruption processing program is stored in a ROM 12. This interruption processing program previously includes a process step for outputting analog signals of specific level from a D/A converter 14. Then an oscilloscope (display means) 14 displays the output of the D/A converter 13 on the time base so that it can be observed. A multibus 15 consists of a data bus, an address bus, etc. Consequently, while the program is run, the actual operation state of the program can directly be confirmed.
