A Hardware/Software Co-design Method Using Real Time Evaluation of Re-use Components and its Verification

The trade-off between hardware and software is an important matter in hardware/software co-design. In embedded systems which develop immense software, the implement ability of software re-use serves as a key of development success. In this paper, we propose a co-design method using real-time evaluation of re-use parts. The co-design method uses processing time, memory, and number of gates as trade-off conditions. System level language SpecC is used for realizing the proposed method. We applied the method to ITS (Intelligent Transport Systems) safe driving support system and evaluated the effectiveness of the method.
