Abstract
Fast scheduling mechanism of tasks to be performed in a communication system, like a modem, and the scheduler for implementing the mechanism. The communication system receives, synchronously to a rate determined by a high priority program, data to be processed by the tasks of a lower priority main program. Instead of scheduling the tasks immediately upon requests generated by an interrupt program, said tasks are scheduled with a controled delay relatively to their corresponding requests. Thus, free processing windows are created for execution of asynchronous tasks or synchronous transient overloads. Overall, more synchronous and asynchronous tasks can be performed without increasing processing power.
