Autonomous reconstruction soft configuration method for SoPC chip

The invention discloses an autonomous reconstruction soft configuration method for a SoPC chip. The autonomous reconstruction soft configuration method is obtained by researching an autonomous reconstruction soft configuration circuit technology of the SoPC chip. According to the autonomous reconstruction soft configuration method, the characteristic that configuration interfaces are controllable is fully used, the GPIO interface of a processor is connected with the configuration interface of an FPGA chip, a physical data path and a configuration link are constructed, time sequence configuration and data configuration are achieved through control over signal output and collection of the GPIO interface and level fluctuations of the interfaces, and then autonomous reconstruction is completed. Compared with a traditional reconstruction configuration method, autonomous reconstruction of a system can be achieved without additionally arranging a special configuration chip for an FPGA in the SoPC chip, the size of the SoPC chip is effectively reduced, few signals for controlling autonomous reconstruction exist in the SoPC chip, and therefore the designing complexity is lowered.
