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该提案研究了一类新的处理器及其相关的编译器，Tiger处理器，它将通用处理器与可配置功能单元（RFU）紧密耦合。 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RFU，在需要时，可以配置RFU来实现与任何单独应用相匹配的硬件。 Tiger处理器可以在所有级别上实现应用程序的并行性：MIMD、SIMD、指令级、流水线和位级。实现这些处理器的潜力的两个要求，在本建议中进行了研究，是（1）开发健壮的编译器，从任何高级编程语言快速产生有效的可执行程序，（2）研究RFU与通用处理器之间的接口问题，目的是使程序在通用设备上获得接近定制硬件的性能。 Tiger处理器将提高系统性能并降低系统成本，因为不需要用定制硬件及其相关的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.
