Document Type and Number:
Japanese Patent JP7095513
Kind Code:
B2
Abstract:
To easily monitor whether or not a parallel program is processed in a determined execution order.SOLUTION: A multi-core microcomputer 21 of an on-vehicle unit 20 comprises a monitoring part 21e for acquiring information related to processing MT1-MT8 executed on a plurality of cores 21c, 21d and monitoring whether or not, data access is executed in an order regulated in an access order information table 21a2' based on access order information generated by a parallelizing tool. Therefore the invention can allow confirmation of whether or not, the parallel program 21a1' is executed in a correct order, and, a control object appliance is normally controlled. Therefore, when controlling the control object appliance by the generated parallel program 21a1', the function safety can be secured.SELECTED DRAWING: Figure 6
