摘　　要：对于多核DSP应用来说,Boot Load技术以及动态部署是核心关键点,针对实现多核DSP快速的、多级加载的以及可在线动态部署的目的,该文设计了一种基于EMIF(External Memory Interface)的多级加载与基于以太网接口的在线动态重构方案。从内核一级启动开始,对传统的EMIF二级启动进行修改,并将存储区进行分区管理,实现动态重构。通过研发的测试板进行试验,结果表明,基于EMIF的多级加载是成功的,并且能够实现在线动态部署,验证了该设计的正确性与有效性。For multi-core DSP applications,Boat Load technology and dynamic deployment are the key points. For the purpose of realizing fast,multi-stage loading and online dynamic deployment of multi-core DSP,thispaper designs a multi-stage loading scheme based on EMIF(External Memory Interface)interface and an online dynamic reconfiguration scheme based on Ethernet interface. Starting from the kernel one stage boot,the scheme modifies the traditional two stage boot of EMIF,and the storagearea is partitioned to achieve dynamic reconfiguration. Through the test board developed by ourselves,the results show that the multi-stage loading based on EMIF interface is successful,and the online dynamic deployment can be realized,which verifies the correctness and effectiveness of the design.
