The design of system-on-a-chip (SoC) circuits requires the integration of complex hardware/software components that are customized to efficiently execute a specific application. Nowadays, these components include many different embedded processors executing concurrent software tasks. In this paper, we present an object-based component interconnection model to represent both hardware and software components within a system architecture in a very high level of abstraction. This model is used in a design flow for automatic generation of hardware/software interfaces for SoC circuits. Design tools for automatic generation of embedded operating systems, hardware interfaces and associated device drivers are presented and evaluated using the results obtained with a VDSL application.
