DEVICE AND METHOD FOR SUPPORTING SOFTWARE DEVELOPMENT AND RECORDING MEDIUM HAVING THE SAME PROGRAM RECORDED THEREON

摘要

PROBLEM TO BE SOLVED: To reduce the load of a debug work by detecting any illegal access to shared resources controlled by a semaphore in a multi-task OS. SOLUTION: This software development supporting device is provided with an illegal access detecting part 31 for monitoring the execution of a memory access instruction during the execution of a user application 1, detecting access to the shared resources by referring to shared resource information storing the designated information of each shared resource of a multi-task OS 2, and detecting any illegal access by comparing the access task ID of an OS state table with a semaphore acquisition task ID.
