Embodiment 1

[0029] This embodiment assumes that the system has N tasks, the nth task is represented by TASKn, the nth timer is represented by TMRn, the nth event is represented by EVENTn (the nth semaphore is represented by SEMn, the nth mutual exclusion signal The amount is represented by MUTEXn, the nth semaphore set is represented by SEMFn, the nth message mailbox is represented by MBn, and the nth message queue is represented by MQn).

[0030] The core modules of the hardware real-time operating system HRTOS involved in this embodiment include a system timer manager 1 , an event manager 2 , a task manager 3 and a bus interface manager 4 . Wherein, the timing manager 1 includes a timing timer array, a timing waiting table and a timing ready logic. The timer array includes N timers, and each task is fixedly assigned a timer to realize the delay and periodic execution of the task. When the timer TMRn of n tasks TASKn arrives regularly, then according to whether the nth bit of the timing ...
