Are there any document discribes how long the function of  TSK_sleep(1) delays the task?

Thank you for your replying!

Best regards,

    Hi GangLing,

    Take a look in the BIOS API reference doc (CCS->Help->Help Contents->DSP/BIOS->API Reference.

    Please note the following

    "The actual time delayed can be up to 1 system clock tick less than timeout due to granularity in system timekeeping"

    For example, let's assume the system tick is 1ms. If you call TSK_sleep(1) and the system tick occurs 5 microseconds later, your sleeping task will start to run (assuming there are no other tasks of equal or higher priority running).
