| Abstract: | This paper presents MASA stream architecture which supporting 64b operation for scientific computing,and which characteristics are stress locality,parallelism,decoupling of memory operations.It matches the capabilities of modern semiconductor technology with computer-intensive parallel applications and allows for high performance of compiler optimized code.Given a fluid computing application as a case,the authors used a cycle-accurate hardware simulator to analyze the performance of the implementation and to measure application run-time.A comparison with the code,tuned for traditional general purpose processors,confirms the stream processor's potential to deliver high performance. |
