In recent years, all kinds of information devices have come to handle a large amount of data, and fast processing for a large amount of data contributes directly to the performance of information and communication devices. Especially, data exchange between such information equipment has become an overhead that degrades the performance in recent years. However, rapid data production growth does not stop even if the network speed is getting improved. Focusing on data compression technology at exchanging data among the information devices in ultra-high speed, we have developed a new data compression technology that can be implemented compactly and with high performance even for implementation in small devices such as embedded systems. We have projects to address the problems to provide scalable embedded systems with fast data exchange by the data compression technology.
