A New Schedule Strategy of Embedded Multi-core SoC

摘要

In this paper, we propose the weighted least-connection (WLC) task schedule strategy for isomerism architecture SoC. Each core communicates with other cores through mailbox. The master core has two main threads: communication thread and task allocation thread. The slave core has two threads: communication thread and data deal thread. The dynamic weighted least-connection task schedule strategy takes each core's computing performance and each core's real-time processing information into consideration to make each core's load balanced and to reduce the congestion. We do the experiment on Xi-linx V5 platform and compare dynamic weighted least-connection task schedule strategy with round-robin task schedule strategy.
