This book constitutes the refereed proceedings of the 8th IFIP WG 10.2 International Workshop on Software Technologies for Embedded and Ubiquitous Systems, SEUS 2010, held in Waidhofen/Ybbs, Austria, in October 2010. The 21 revised full papers presented together with the abstracts of two invited talks were carefully reviewed and selected from 30 submissions. The papers are organized in topical sections on hardware, real-time systems, model-based design and model-checking, sensor nets, error detection and system failures, hard real-time, middleware and smart spaces, and function composition and task mapping.
