A DSP on-
orbit reconfiguration and configuration loading method and
system, the steps are as follows: the
control circuit receives the data to be reconfigured and carries out analysis
processing; the data to be reconfigured after analysis
processing is written into the program data
storage area of the continuous address of Flash in sequence according to the
programming timing requirement of FLASH; the
control circuit carries out logical reset to the reconfigured loading DSP; after reset is completed, the reconfigured loading DSP device sends the
continuous data address to the on-
orbit reconfiguration and loading
control circuit in sequence; the on-
orbit reconfiguration and loading control circuit carries out address decoding to the received data address, and maps out the program data
storage area address in the corresponding Flash, reads the program data from the corresponding program data
storage area of the Flash in sequence, and places the continuous address data on the configuration interface according to the configuration interface timing requirement of the reconfigured loading DSP, until all the continuous address data required by the reconfigured loading DSP is read completely, and the loading is successful.
