一种基于DSP的全局动态可重构方法OACSTPCD
Global dynamic reconfigurable method based on DSP
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 multi-core platform,DSP has few researches on its reconfiguration,which limits the ap-plication of this technology.To solve this problem,a global dynamic reconfiguration method based on DSP is proposed.Pre-partition 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 com-plete 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.
