[Clock tick trigger by user]

Hello ,

One question about clock tick that is triggered by user in sys/bios.

If the user triggers the clock tick then the scheduling between task is handled by user?

If we have the following scenario:

Task A is waiting in a semaphore and task B post this semaphore.

Task A will wake up when the clock tick is increased by user ?

Best regards

George,

I don't think the user has to handle scheduling.

Yes, if Task A has higher priority than Task B.

Hello,

Thank you for the prompt reply.

Yes means that the Task A will be waken up by Task by only when the user increases the clock tick or when the Task A is waken up is independent on clock_tick that the user increases

Best regards

George,

TI-RTOS Kernel is event driven not time sliced. When the semaphore is posted, scheduler determines if there a Task of higher priority to run.

Please refer to SYS/BIOS page for detailed information and technical documents.
