Method of task management in multi-tasking operating system for computer controlling a motor vehicle

摘要

The task management uses an interrupt (SPIO) to interrupt individual tasks when a higher priority task is active. A stack region (313a) provides workspace for individual tasks (SPAO, SPBO, SPCO) and handles their interruption in a separate stack region (313b). A region is established to manage the stack pointer (313c) for each individual task and for the interruption.
