Design and Realization of Realtime Performance of Embedded Linux
LA Information · Computer and Digital Engineering · 2009
The linux kernel is modified as designing scheme using realtime performance of Embedded Linux in celerity self-healing router-protocol and experiment system.The low-latency scheme is adopted and preemption scheme to improve the preemptive ability of linux kernel,and one of the running queue in Linus system is modified by replacing with mulitiple running queues.we give each running queue a sign to show whether it is vacant or not,and there is a variable to indicate the highest priority queue,linux will take a task from the highest priority running queue when process schedule it.
