Vehicle-mounted microcomputer comprises a core holding element that determines whether preset stop condition of each virtual core of single core is fulfilled and stops a virtual core, when stop condition is fulfilled

摘要

The microcomputer (1) has a single core (11) of resource used on time-shared manner such that virtual cores (21-24) including core activation element and core holding element are provided in the single core. The activation element determines whether preset condition of each activation element is satisfied. The activation element is executed to activate one of the virtual cores when preset condition is satisfied. The holding element determines whether preset stop condition of each virtual core is fulfilled and stops a virtual core when stop condition is fulfilled.
