VxWorks下龙芯3A中断控制技术的研究
Research on interrupt control technology of Loongson 3A based on VxWorks
摘要
Abstract
Interrupt control is the base of normal running of the embedded operating system VxWorks and is a safeguard of high real-time performance.A drive hierarchical model of interrupt control on VxWorks is proposed aiming at the characteristics that the drive development of interrupt control on the embedded operating system VxWorks has great difficulty and its wide application.According to this model,a design method of interrupt control drive software based on VxWorks is put forward.The interrupt control drive software of Loongson 3A have was developed successfully with the method.A method to optimize the Loongson 3A interrupt control performance is presented.It greatly shortens the interrupt response time,and improves the performance of the system.关键词
