Abstract:
In a signal processor including storage sections, a start address for starting output of data from an external memory, is input from an external controller to the start address input section. The signal output section outputs a start signal based on a download start instruction from the external controller, and outputs an end signal when download is completed. The output instruction section outputs, based on the start signal, to the external memory a data output instruction of download data for a designated storage section, starting from the start address, and stops output of the data output instruction based on the end signal. The write instruction section outputs a write instruction to the storage sections that allows data writing only to the designated storage section, and the download data is written to the designated storage section when the start signal is input to the output instruction section.
