Optimization of memory organization and hierarchy for decreased size and power in video and image processing systems

Video and image processing applications deal with large amounts of data which have to be stored and transferred. As the initial system specification describing these data manipulations heavily influences the final memory organization and hierarchy, there is a clear need for exploration support. We believe that the emphasis should lie on fast but accurate estimation and on the high-level steering of the involved system transformations. In this paper, a system exploration environment called ATOMIUM, is presented that supports these requirements. To illustrate the effectiveness of our approach, two realistic demonstrators are worked out and design results are described
