Agile Development Methodology for Embedded Systems: A Platform-Based Design Approach

This paper describes an agile development methodology which combines agile principles with organizational patterns and adapts them to build embedded real-time systems focusing on the system´s constraints. The hardware/software partitioning and platform-based design are used in the proposed methodology to support the embedded system designer meet the system´s constraints in an iterative and incremental way and to reduce substantially the design time and cost of the product. To discuss the strengths and weakness of this methodology, a case study involving a pulse oximeter is also presented
