Abstract: T-Engine is an open standard platform for next generation real-time embedded system of ubiquitous computing system, which consists of standard hardware architecture T-Engine and standard open-source operating system kernel T-Kernel. It has excellent performance in executing speed and porting. This paper introduces the specifications of T-Engine hardware and software. An instance for the platform’s application in the area of embedded system development is given according to the design of a portable individual information searching system based on fingerprint recognition. The results show that the T-Engine platform meets the demands in system volume, power restrict and real-time requirement.

Key words: T-Engine platform, real-time embedded system, ubiquitous computing, fingerprint recognition
