Free registration required

Executive Summary

Embedded application is a hotspot at present and Linux gradually becomes the most important operating system for embedded applications. Aiming at the real-time problems of Linux and from five performance parameters of real-time operating system, this paper analyzes and concludes that scheduling latency and interrupt latency are the fundamental constraints for improving real-time performance of Linux 2.6 kernel, then designs and implements a new task model and new interrupt operations to solve the above problem.
