Embedded system integrated application, operating system and computer hardware. Currently rely solely on improving processor performance, to improve the system of real time has been unable to meet the needs of data processing of embedded system. Present a new architecture, the use of heterogeneous multi-processor to ensure real-time, parallel processing technology to improve the system, the use of redundancy to improve reliability. System used in the design of domestic processors, dual redundant hot backup and dynamic technologies, some of the requirements of high reliability, fast areas of real-time control is important.%嵌入式系统是将应用程序和操作系统与计算机硬件集成在一起的系统,目前对嵌入式系统数据处理需求在不断提高,单纯依靠提高处理器的性能,来提高系统的实时性已经无法满足.提出了一种新的架构,在系统中使异构多处理器来保证实时性,采用并行技术,同样有助于提高系统的处理能力,再加上系统采用冗余备份,有助于提高可靠性,在设计中采用国产处理器,双机冗余备份及存储系统,动态热备份技术,对要求可靠性高、速度快的实时控制领域具有重要意义.
