Abstract

The Imagine processor is designed to address the processor-memory gap through streaming technology. Good performance of most media applications has been demonstrated on Imagine. However the research whether scientific computing applications are suited for Imagine is open. In this paper, we studied some key issues of scientific computing applications mapping to Imagine, and present the experimental results of some representative scientific computing applications on the ISIM simulation of Imagine. By evaluating the experimental results, we isolate the set of scientific computing application characteristics well suited for Imagine architecture, analyze the performance potentiality of scientific computing applications on Imagine compared with common processor and explore the optimizations of scientific stream program.
