<p>PROBLEM TO BE SOLVED: To shorten time required for writing, on a nonvolatile memory, the entire writing data for writing on the nonvolatile memory, in an electronic control device for an automobile.SOLUTION: An ECU 100 performs, in parallel, reception processing for receiving divided data obtained by dividing writing data and copying the received divided data to one of first and second buffer areas 133 and 134 and processing for writing the divided data stored in the other buffer area to a ROM 110 by using the other buffer area. Further, the ECU 100 uses the buffer area that has been used in the reception processing for next write processing, and uses the buffer area that has been used in the write processing for the next reception processing.</p> |
