CAREER: Architectures and Compilers for Tiger Machines

CCR-9876248 CAREER：Tiger机器的体系结构和编译器Seth Copen Goldstein本提案研究了一类新的处理器及其相关的编译器-Tiger处理器，它将通用通用处理器与可重构功能单元(RFU)紧密结合在一起。RFU可以在运行时配置为实现硬件电路的功能。TIGER处理器提供通用微处理器的灵活性和定制电路的性能。TIGER处理器提供高性能和高效率，因为它们包含一个RFU，当需要时，可以配置该RFU来实现与任何单独应用匹配的硬件。TIGER处理器可以在MIMD、SIMD、指令级、流水线和位级上实现应用程序的并行性。实现这些处理器的潜力的两个要求是：(1)开发健壮的编译器，快速地从任何高级编程语言产生高效的可执行文件；(2)研究RFU和通用处理器之间的适当接口。本研究的目的是使程序能够从通用设备上获得接近定制硬件的性能。Tiger处理器将既提高性能又降低系统成本，因为将不需要使用定制硬件及其相关设计开销来增强系统。

CCR-9876248CAREER: Architectures and Compilers for Tiger MachinesSeth Copen GoldsteinThis proposal investigates a new class of processors and theirassociated compilers, Tiger processors, which TIghtly couple aGEneral-purpose processor with a Reconfigurable function unit (RFU).The RFU can be configured, at run-time, to implement a function as ahardware circuit. Tiger processors offer the flexibility of ageneral-purpose microprocessor with the performance of a customcircuit.Tiger processors offer high performance and efficiency because theycontain an RFU, which, when needed, can be configured to implementhardware matched to any individual application. Tiger processors canrealize an application's parallelism on all levels: MIMD, SIMD,instruction-level, pipeline, and bit-level.The two requirements to realizing the potential of these processors,investigated in this proposal, are (1) developing robust compilerswhich quickly produce efficient executables from any high-levelprogramming language, and (2) investigating the proper interfacebetween the RFU and the general-purpose processor.The objective of this research is to allow programs to obtainperformance approaching that of custom hardware from a general-purposedevice. Tiger processors will both increase performance and reducethe cost of systems because there will be no need to augment systemswith custom hardware and its associated design overhead.
