传统单核心控制器受制于硬件结构相对封闭,可控参数有限,一定程度上影响了工艺过程控制的灵活性。设计一种开放式的控制器,实现过程控制网络化是当今物联网发展的趋势。文章基于嵌入式Linux系统平台,使用高速双端口RAM芯片CY7C024AV2,提出一种模块化的DSP与ARM的双核通信模块方案及其驱动程序的设计,实现了控制器的双核数据通信功能,为控制器的网络智能控制建立了软件基础。实验证明,该驱动程序的支持下控制器的双核数据通信性能满意。
傳統單覈心控製器受製于硬件結構相對封閉,可控參數有限,一定程度上影響瞭工藝過程控製的靈活性。設計一種開放式的控製器,實現過程控製網絡化是噹今物聯網髮展的趨勢。文章基于嵌入式Linux繫統平檯,使用高速雙耑口RAM芯片CY7C024AV2,提齣一種模塊化的DSP與ARM的雙覈通信模塊方案及其驅動程序的設計,實現瞭控製器的雙覈數據通信功能,為控製器的網絡智能控製建立瞭軟件基礎。實驗證明,該驅動程序的支持下控製器的雙覈數據通信性能滿意。

The flexibility of process control is greatly affected by the relatively closed hardware architecture and limited amount of control parameters. It is a trend to develop a smart controller with open hardware architecture which can make it possible of control process network. With the use of Dual-Port RAM CY7C024AV2,A dual-core solution with DSP and ARM is presented,as long as the driver development under embedded Linux for the dual-core controller module. The driver presented provided software basis for intelligent network control methods. Experiment result shows that the driver can achieve a good performance on inter-core communication.
