Optimization of Embedded Operating System RTEMS Based on Multiprocessor
Xuejun Yang · Jisuanji gongcheng · 2007
With the popularity of multiprocessor embedded system,like many other embedded operating systems,RTEMS,as a great open source embedded operating system,also supports parallelization.However,RTEMS's multiprocessor support may cause deadlock on multiprocessor system.And it may cause severe performance damage to the hardware when distributing data in data processing system.Based on an onboard computer research,this article improves RTEMS's multiprocessor support and will work out an optimization for RTEMS's performance bottleneck that may occur in data distribution.
