【摘要】 论文基于DSP+ARM双核异构芯片OMAPL138,提出了一种新的塞拉门车门控制方案。介绍了双核门控器的硬件构成及软件设计,详细介绍了处理器的DSP核与ARM核之间的通信机制与实现方式。DSP核用于对车门状态的采样处理及电机控制,ARM核用于存储诊断信息及与外界通信,DSP与ARM核间通信通过Syslink组件及其通信协议实现。该设计已成功替换现有的两个独立核心板的设计方式,且工作状态良好。更多还原

【Abstract】 Based on the DSP+ARM dual-core heterogeneous chip OMAPL138,this article presents a new design scheme for the sliding plug door controller. This design illustrates the hardware and the software design of the dual-core sierra gate controller,and introduces in detail about the communication mechanism and realization mode between the DSP-core and the ARM-core.DSP-core is used for sampling and motor control of the door status. The ARM-core is used for storing diagnose information and communicating with the outside equipment. The communication between DSP-core and ARM-core is realized through the communication protocol in the Syslink component. This design has successfully replaced the existing two core-broads design mode,and the working condition is good.更多还原
