摘要
为推进国产数字信号处理器(DSP)芯片的推广与应用,以基于华睿2号芯片的信号处理模块为硬件平台,介绍板级支持包(BSP)的基本设计思想和关键技术。介绍了芯片内部多核同步与模块内部多DSP同步的设计方法,有效提升嵌入式处理系统的启动性能;描述了高可靠文件系统的配置过程与设计方法。该BSP已在多个产品型号中实际应用,为基于华睿2号芯片的基础软件设计和应用程序开发提供参考。
To improve the popularization and application of domestic digital signal processor(DSP)chips,using the hardware platform of the signal processing module based on Huarui2 DSP,describring the basical design idea and the key technology of the board support package(BSP).Introducing the design method of multi-core synchronization inside the chip and multi-DSP synchronization inside the module,improving the startup performance of embedded system effectively.The configuration process of reliance file system is described.The BSP has been applied in many products,the paper provides reference for basic software design and application development based on Huarui2 chip.
