This project will investigate the architecture and design of a single-chipparallel computer system. As technology continues to improve and transistorsizes decrease, the latency of on-chip interconnect wires will have agreater impact on the performance of computer systems. In the future,computer designers will need to develop architectures that avoid the use oflong interconnect wires in order to reduce the effect of this latency. Onesuch approach would be to include a number of small, simple processorstogether on a single chip, forming a single-chip parallel computer. Thiswould reduce the effect of the latency because the length of theinterconnect wires would depend on the size and complexity of theindividual processors, not the size of the entire system. By keeping theprocessors simple, long interconnect wires will not be necessary. Thechallenge to designing such a system is determining the features that thearchitecture must include. This research project will investigatearchitectural features that provide low-overhead support for parallelprograms, applying them to the design of the SCMP (Single-ChipMessage-Passing) parallel computer. Through the extensive use ofsimulation, the design and performance of the SCMP system will be analyzedand compared to other computer architectures.

该项目将调查单芯片处理的计算机系统的体系结构和设计。随着技术的不断改善和跨性降低，芯片互连电线的延迟将对计算机系统的性能产生影响。将来，计算机设计人员将需要开发避免使用长互连线的体系结构，以减少该延迟的效果。 OneSuch方法是在单个芯片上包括许多小型，简单的处理，形成单芯片并行计算机。这将减少延迟的效果，因为接口电线的长度取决于个体处理器的大小和复杂性，而不是整个系统的大小。通过使处理器简单，长互连线将不需要。设计这样的系统正在确定Thearchitecture必须包含的功能。该研究项目将调查对平行程序提供低离子支持的搜索特征，并将其应用于SCMP（单chipmessage-passage）并行计算机的设计。通过大量仿真，将分析SCMP系统的设计和性能与其他计算机架构相比。
