METHOD AND SYSTEM FOR DEDICATING PROCESSORS FOR DESIRED TASKS

摘要

Improving the performance of multitasking processors are provided. For example, a subset of M processors within a system with N processors is dedicated for a desired task. The M (where M>0) of the N processors are dedicate to a task, thus, leaving N−M (N minus M) processors for running normal operating system (OS). The processors dedicated to the task may have their interrupt mechanism disabled to avoid interrupt handler switching overhead. Therefore, these processors run in an independent context and can communicate with the normal OS and cooperation with the normal OS to achieve higher performance.

1. A method for improving the performance of a multi-processor system, the method comprising:
providing M processors from N processors to perform a desired task, wherein N is greater than M; and modifying the M processors, wherein the modification of the M processors prevents the M processors to perform tasks other than the desired task and the N−M (N minus M) processors continue to perform operating system operations.
