MULTITASKING PROCESSOR AND TASK SWITCHING METHOD THEREOF

Abstract

A multitasking processor and a task switching method thereof are provided. The task switching method includes following steps. A first task is executed by the multitasking processor, wherein the first task contains a plurality of switching-point instructions. An interrupt event occurs. Accordingly, the multitasking processor temporarily stops executing the first task and starts to execute a second task. The multitasking processor executes a handling process of the interrupt event and sets a switching flag. After finishing the handling process of the interrupt event, the multitasking processor does not perform task switching but continues to execute the first task, and the multitasking processor only performs task switching to execute the second task when it reaches a switching-point instruction in the first task.
