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 application 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 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.
