Abstract

Ever growing ubiquitous environment demands security, speed, and power consciousness in processing huge amount of multimedia information. A practical solution to meet these demands is the construction and implementation of a safety aware, highly-performed, and sophisticated architecture. According to this scheme, we have exploited a secure ubiquitous system composed of a hardware cryptography-embedded multimedia mobile architecture and its software support. The architecture is a dedicated single chip processor called HCgorilla. Since one-sided hardware design approach does not always sufficient for the development of HCgorilla, we have followed an H/S co-design scheme. The software support includes a Java interface and parallelizing compilers run on servers to reduce the load and increase the performance of HCgorilla-embedded clients.
