Abstract
The invention relates to a method of executing a real-time task by a digital signal processor using a cache memory, an overall duration being allocated for executing said task and any interrupts coming from peripherals associated with the processor, wherein the overall duration is subdivided into a plurality of time intervals comprising at least one masked period during which said task is executed and interrupts are made to wait and are grouped together, and at least one non-masked period during which said task is suspended and the group of interrupts is executed. The masked periods and the non-masked periods are defined by a hardware mechanism including a timer.
