摘　　要：可重构计算技术很好地解决了计算性能、效能,以及灵活性之间的矛盾,DSP作为异构多核平台中极为重要的组成部分,却少有面向其可重构的研究,限制了该技术的应用。针对此问题提出一种基于DSP的全局动态可重构方法。预先分区FLASH并烧写SPI参数文件以及镜像文件A、B,系统启动后先运行镜像A,当收到重构命令时修改SPI参数,将BOOT使用的镜像指向B,最后控制DSP重新BOOT以完成重构。使用TI TMS320C6678 DSP做测试,结果表明,该方法可以在320 ms内完成DSP内运行镜像的切换,具有良好的应用前景。Reconfigurable computing technology solves the contradiction between computing performance,efficiency and flexibility very well.As a very important part of heterogeneous multicore platform,DSP has few researches on its reconfiguration,which limits the application of this technology.To solve this problem,a global dynamic reconfiguration method based on DSP is proposed.Prepartition FLASH memory and burn SPI parameter files as well as image files A and B.After the system starts,it runs image A first.When receiving the reconstruction command,modify SPI parameters to point the image in BOOT to B.Finally,control the DSP to restart BOOT to complete the reconstruction.The test results of TI TMS320C6678 DSP show that this method can complete the switching of DSP running image within 320 ms,and has a good application prospect.
