CAREER: Future Values: Reshaping the Future of Instruction Level ParallelismAbstractThis research aims at providing an effective solution to the fetch problem of instruction level parallel processors. With the concept of "future values", one can represent traditional programs in a new control-flow form such that on any control flow path the data-flow aspect of the computation is either traditional (i.e., definition of a value precedes its consumers), or reversed (i.e., consumers of a value precedes its definition). The representation hence allows ordering of instructions even when the data dependencies would prohibit doing so in a control-flow graph. As a result, it is possible to seamlessly exploit control independence, use predication to eliminate any branch instruction, and design processors, which can reuse the internally generated dataflow graph as another source of instructions. This approach has the potential to significantly impact the design of processors and optimizing compilers, and positively affect every field of science and commerce that relies on processor performance. The project will also result in course materials and software tool sets that will be made publicly available. Finally, the project will contribute greatly to the development of the recently initiated Computer Science Ph.D. program at Michigan Technological University.

职业：未来价值观：本文旨在为指令级并行处理器的取指问题提供一种有效的解决方案。 利用“未来值”的概念，可以以新的控制流形式表示传统程序，使得在任何控制流路径上，计算的数据流方面要么是传统的（即，值的定义先于其消费者），或者反向（即，值的消费者先于其定义）。 因此，即使在控制流图中数据依赖性禁止这样做时，该表示也允许指令的排序。因此，可以无缝地利用控制独立性，使用预测来消除任何分支指令，并设计处理器，其可以重用内部生成的分支图作为另一个指令源。这种方法有可能对处理器和优化编译器的设计产生重大影响，并对依赖处理器性能的每个科学和商业领域产生积极影响。该项目还将产生公开提供的课程材料和成套软件工具。最后，该项目将大大有助于最近启动的计算机科学博士学位的发展。密歇根理工大学的项目。
