A New Approach for Distributed Computing in Embedded Systems
Historically, a typical embedded system has been designed as a control-dominated system using only a state-oriented model, such as FSMs. However, the trend in embedded systems design in recent years has been towards highly distributed architectures with support for concurrency, data and control flow, and scalable distributed computations. This implies that a different approach is necessary. We propose to use some dataflow computational model views to specify embedded systems, because it is a notation that covers the most relevant aspects of distributed computing. In this paper, we introduce a new computational model, known as OAA (Object-Attribute Architecture) and present the general characteristics of an OA-methodology to support the design and simulation of distributed computing systems. The matrix multiplication algorithm in the object-attribute distributed computing environment has been used to validate our methodology. The preliminary evaluation results show the feasibility of the OA approach.
