摘要
实时和海量任务强处理能力是提高控制系统运行效率的有效方式。因而很多控制系统采用多处理器和多计算机处理方式。但是在处理器和计算机之间的通信能力却是影响其效果的瓶颈。提出了一种解决方法:利用双端口RAM实现全局共享和弱冲突访问。并讨论其结构与工作原理,分析其效果。理论和实验结果证实了此存储器可以极大地增强处理器和计算机之间的通信能力。
Real-time and huge tasks proeessing is effeetive method to improve eontrol system operating effieieney.So multi-processor and muhi-eomputer is adopted in eontrol system.But the eommunication ability among proeessors and computers is the bottleneek of effeeting performanee.The paper presents a solution with global share and feebleness eon- filet aecess using dual-port RAM.And its strueture and work prineiple are diseussed and its performanee is analyzed. The theory and results of experiment show the memorizer ean improve the eommunieation ability among proeessors and eomputers greatly.
