This book introduces the concept of approximate computing for software and hardware designs and its impact on the reliability of embedded systems. It presents approximate computing methods and proposes approximate fault tolerance techniques applied to programmable hardware and embedded software to provide reliability at low computational costs. The book also presents fault tolerance techniques based on approximate computing, thus presenting how approximate computing can be applied to safety-critical systems.
Introduction.- The Approximate Computing Paradigm.- Radiation Effects on Digital Devices.- Methodologies for Testing and Assessing Approximate Computing Systems.- Embedded Systems Fault Tolerance.- Conclusion.
Gennaro Severino Rodrigues got his Ph.D. in Microelectronics from the Universidade Federal do Rio Grande do Sul (UFRGS, Porto Alegre, Brazil), in cooperation with LIRMM (Montpellier, France) and the Ecole Centrale de Lyon (France). His research is focused on Approximate Computing and Fault Tolerance, and he has been working on the development of embedded software for safety-critical applications and fault tolerance techniques. His interests are also in Machine Learning and its relation to approximate computing and fault tolerance.
