The Modelling of Embedded Systems Using HASoC

Abstract

We present a design method (HASoC) for the lifecycle modelling of embedded systems that are targeted primarily, but not necessarily, at SoC implementations. The object-oriented development technique is based on our experiences of using an existing modelling technique (MOOSE) and supports a lifecycle that explicitly separates the behaviour of a system from its hardware and software implementation technologies. The design process, which uses a UML-RT-based notation, begins with the incremental development and validation of an executable model of a system. This model is then partitioned into hardware and software to create a committed model, which is mapped onto a system platform. The methodology emphasises the reuse of preexisting hardware and software platforms to ease the development process. An example application is presented in order to illustrate the main concepts in HASoC.
