一种总线系统实时数据嵌入式存储方法

摘要

This paper presents a method for real-time data embedded memory of a bus system.This method uses Freescale's main processing chip 9S12X series dual-core microcontroller,the storage medium for the IDE interface SSD,the main processing core 9S12X controller chips to perform online data is written to or read from SSD tasks,monitor the implementation of co-processing of nuclear data bus and receiving tasks.Usage requirements set forth a complete hardware and software design solutions this paper,to better realize the amount of embedded memory bus Shanghai real-time data.%提出了一种总线系统实时数据嵌入式存储的方法。该方法中主处理芯片采用Freescale公司9S12X系列双核单片机，存储介质为IDE接口固态盘，9S12X主控芯片的主处理核执行在线数据写入或读出固态盘任务，协处理核执行总线数据的监听和接收任务。结合使用需求阐述了完整的硬件和软件设计方案，较好地实现了总线上海量实时数据的嵌入式存储。
