ABSTRACT

This paper presents the technology for remote system updating that allows software updates in embedded systems such as mobile phones and car navigation systems. Software updates are carried out using binary difference, software construction, and fast compression technologies. In this paper, we focus on a fast BPE (byte pair encoding) method of encoding program codes in embedded systems and show the index of relations between the updating time and the downloaded data size.
