摘　　要：针对双核微处理器在工业控制领域的应用,探讨了基于共享内存的双核处理器软件架构的设计方法,主要分析讨论了双核之间的通信方法、数据共享策略以及双核任务分配方法。以F28M35双核处理器为例,介绍了该处理器资源结构、双核间的通信机制以及共享内存的使用方法。设计了一种以系统控制块数据结构为核心的软件架构方法,并成功运用在注塑机控制系统中。Aiming at applications of dual-core microprocessor in the field of industrial control, this paper discusses the design methods of dual-core processor＇s software architecture based on the shared memory, mainly involving dual-core, communication methods, data sha- ring strategies and the methods for dual-core task allocation. Taking F28M35 duai-core processor as an example, this paper describes the structure of the processor resources, the dual-core communication mechanisms and uses methods of shared memory. A software archi- tecture method is designed based on the data structure named system control block, and the method is successfully applied in control systems of injection machines.
