摘要
实现嵌入式系统任务的并行性是改善系统性能的基本手段。通过分析影响嵌入式系统性能的主要因素,采用了基于线程概念的嵌入式系统并行设计方法,利用指令级并行来改善系统性能。主要论述了线程集成的实现方法,通过编译技术在指令级代码中融合多个线程,从而实现任务的并行性,并将该方法应用于仪器仪表显示模块的设计。
Implementation task concurrency is the basic means of improvement system performance.By analyzing factors impacting upon the embedded system performance,an embedded system design method based on thread ideas is used,performance is improved with instruction level parallelism.The implementation of thread integration is discussed,the implementation of task concurrency with compiler technology integrating multiple threads at the instruction code level is described and used at display module in the field of instrument.
