This paper devises a sophisticated approach to the performance estimation of an embedded hardware-software codesign system at the architecture level, which intends to optimize the hardware-software configuration in terms of processing time, power dissipation, and hardware cost. A distinctive feature of this approach consists in constructing a performance estimation model proper to each component of an embedded system, such as CPU core, RAM/ROM, cache memory, and application-specific hardware, by taking account of not only the functional performance but also the data transfer. The proposed estimation schemes are incorporated into an existing instruction set simulator, so that the actual performance can be estimated accurately at the architecture level. The experimental results demonstrate that the performance estimation approach enables the precise design decision at the architecture level, which greatly contributes toward enhancing the design ability dedicatedly for mobile appliances.
