Hardware/Software Co-design of a Secure Ubiquitous System

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 a safety aware, high-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 achieve the overall demands for the secure ubiquitous system, we have followed H/S co-design. 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
