This CAREER proposal addresses new paradigms for exploiting and teaching instruction-level parallelism (ILP). Statically-scheduled microarchitectures achieve high performance by relegating to the compiler the responsibility for detecting and scheduling ILP. Drawbacks to this approach include a lack of object code compatibility between generations, the reliance on program profiles, and the erosion of the individual compilation model. This research will develop new paradigms for ILP that remove the draw-backs by enlisting the OS, the linker, the assembler, the instruction encoding and the microarchitecture. The educational plan will introduce the compiler's role in the undergraduate curriculum as the sophomore and senior levels by developing two courses: "Introduction to Machine Language Programming" will be modified to include an awareness of performance issues and the role of the compiler; and a senior level course will be developed to teach back-end ILP compiler optimization. An important feature of this proposal is the training of graduate students in a fundamentally and technologically significant area of ILP. The research and educational activities will use the TINKER Instruction Set Architecture that has been constructed by the principal investigator and his students.

该职业提案提出了利用和教授指令级并行性 (ILP) 的新范例。 静态调度的微体系结构通过将检测和调度 ILP 的责任委托给编译器来实现高性能。 这种方法的缺点包括各代之间缺乏目标代码兼容性、对程序配置文件的依赖以及单个编译模型的侵蚀。 这项研究将为 ILP 开发新的范例，通过使用操作系统、链接器、汇编器、指令编码和微架构来消除其缺点。 该教育计划将通过开发两门课程，在本科二年级和高年级课程中介绍编译器的作用：“机器语言编程入门”将被修改，以包括对性能问题和编译器作用的认识；将开发高级课程来教授后端 ILP 编译器优化。 该提案的一个重要特点是在 ILP 的基础和技术重要领域对研究生进行培训。 研究和教育活动将使用由首席研究员和他的学生构建的 TINKER 指令集架构。
