An Integrated Methodology for QOS Driven Reusable Component Design and Component Selection

Embedded systems complexity has been increasing drastically in recent years. This had a negative impact on the product development cycle (PDC). The increasing software and hardware concurrency, and the need for architectural optimization, have also complicated the PDC. One way of enhancing system productivity is to exploit the principle of "design-and-reuse" to its full potential. Component-based design is one effective way of implementing "design-and-reuse". However, given a library of components with varying performance parameters and quality-of-service metrics, it is often difficult to select the right components that will satisfy the system requirements. In this paper, we develop an automated process of component selection. We further demonstrate the proposed methodology by applying it for component selection for a network-on-chip (NOC) architecture.
