Document Type and Number:
Japanese Patent JP7139633
Kind Code:
B2
Abstract:
To make it possible to monitor whether or not a processing operation in a multicore microcomputer is normally performed by the fact that a parallel program is executed by the multicore microcomputer.SOLUTION: A parallel program 31a1 includes processes CK1-CK4 for diagnosing the abnormality of hardware of a multicore microcomputer 31. Therefore, it is possible for the multicore microcomputer 31 to diagnose whether the hardware of the multicore microcomputer 31 is operating normally by executing the parallel program 31a1, and hence, to monitor whether a processing operation that utilizes the hardware is normally performed. The execution schedule of the abnormality diagnosis process is determined so that an abnormality diagnosis process is executed in an idle time on condition that the hardware utilized in processing units executed in parallel with an idle item does not duplicate with the hardware to be diagnosed by the abnormality diagnosis process in cores other than a core that is in an idle time in which processing units are not executed.SELECTED DRAWING: Figure 6
