Guest editorial New trends in programming and execution models for parallel architectures, heterogeneously distributed systems and mobile computing

This paper considers the past, present and future of architectures for high performance image processing:. After reviewing a number of representative designs of image processing-specific architectures, four current approaches arc considered in more detail: standard microprocessor technology. DSP processors, parallel processing and dynamically reprogrammable hardware in the form of Field Programmable Gate Arrays (FPGAs). A final section considers which approaches are more likely to be successful in the future. © 1999 Published by Elsevier Science B. V. All rights reserved.
