This paper presents a technology for Over the Air(OTA) updating that allows software updates in consumer devices such as mobile phones and car-navigation systems that are connected to networks, and it adopts NAND flash memories and demand paging technologies. Software updates for these kinds of consumer devices are carried out using the binary difference that minimizes the amount of update data, software construction technologies that minimize the rewriting of flash memories, and fast compression technologies that enables rapid rewriting. This paper focuses on Byte Pair Encoding (BPE), which is one of the most efficient methods of compressing program code in consumer devices that adopts NAND flash memories and demand paging technologies. We describe a fast method of compressing BPE and evaluating it.
