Abstract

This presentation outlines a strategy to design and implement embedded systems as aggregates of reusable components arranged in application-specific frameworks. Called Application-driven Embedded System Development (ADESD), this strategy focuses on the gap between the two most promising methodologies in the field, Model-driven Engineering and Platform-based Design, by offering concrete alternatives to translate Platform-independent Models (PIMs) into Platform-specific Models (PSMs), and also by promoting beyond-platform reuse. As it guides the development of reusable (hardware, software, or hybrid) components that encapsulate scenario-independent abstractions while isolating scenario dependencies as aspect programs, ADESD yields components that can be automatically woven for a variety of execution scenarios modeled as application-specific component frameworks. ADESD main test case, the EPOS system, has been ported to a dozen distinct architectures, including AVR, H8, MIPS, SPARC, PowerPC, and x86, and has been deployed in scenarios as distinct as scientific computing in super computers and sensor networks, thus confirming the reuse status of components developed following ADESD.

Biography
Dr. Antonio Augusto Fröhlich, currently an Associate Professor of Operating Systems, has been at the Federal University of Santa Catarina (UFSC) since 1993. As Head of UFSC's Software / Hardware Integration Lab (LISHA) since 2001, he has coordinated a number of R&D projects on embedded systems, including dedicated operating systems, hardware/software co-design, wireless communication, and power management. Major contributions from these projects materialized within the Brazilian Digital Television System (SBTVD) and Wireless Sensor Network technology for energy distribution and precision agriculture. Dr. Fröhlich received his PhD from TU-Berlin and is currently member of ACM, IEEE, SBC. Since 2009 he is leading a consortium that will develop an Open, Free, Scalable Digital TV Architecture
