Zusammenfassung:PROBLEM TO BE SOLVED: To provide a firmware rewriting device capable of rewriting firmware of a signal processing means by simple work. SOLUTION: An interface 13 reads out firmware data from a USB device 2 connected to a USB terminal 16, and converts the firmware data into I2S data to be transmitted to a DSP 12 via an I2S line. The DSP 12 receives the firmware data of I2S specification via the I2S line, converted into the original firmware data, and rewrites the firmware in a flash ROM 14. COPYRIGHT: (C)2009,JPO&INPIT
