Abstract:

High-performance computing techniques have had a continuous development during the past decade. However, problems like off-chip storage and communicat ion delay remain not truly resolved. Line delay and power consumption problems are more and more obvious. The high-performance computing area is seekingfor a new processor system structure to cope with such problems. Stream processor is a newcomer which is developing rapidly among many newly emerging p  rocessor system structures and has won wide concerns in both research and industry worlds. It has already had good effects in digital processing, multim edia and image processing areas. This paper analyzes several current popular stream processors and points out the application prospects as well as the challenges of the stream architecture in the scientific computing field.
