一种基于CPU占用率的嵌入式系统网络处理调度算法

One Scheduling Algorithm of Network Processing Based on CPU Occupancy Percentage in Embedded System

物联网、云计算飞速发展,众多嵌入式设备需要接入网络,但是嵌入式设备性能和资源有限,过多的注意网络数据的处理,往往占用处理器过多,降低系统整体性能。为了实现终端IP通信和合理调度网络处理对系统中CPU的占用,采用Xilinx公司的FPGA系统平台,移植了瑞士计算机科学院发布的μIPv6协议栈,并提出了基于CPU占用率的嵌入式系统网络处理调度算法,进行验证,可以优化实验平台的嵌入式系统性能。

The Internet of Things and Cloud Computing are in rapid development, and many embedded equipments need to access network, but the performance and resources of embedded equipments are limited. In order to realize the terminal IP communications and to schedule reasonably the occupancy of network processing on CPU, we made use of Xilinx embedded system and ported the protocol stackpμIPv6 issued by Switzerland Institute of Computer Science （SICS）, and put forward one scheduling algorithm of network processing based on occupancy percentage in embedded system and was verified that it can optimize embedded system performance of experiment platform of.
