High-performance microprocessors are the computational horsepower behind all of society's infrastructure. The seemingly unending march of their progress, known to the public as "Moore's Law," has all but slowed owing to semiconductor technology and manufacturing limits. Continued progress requires breakthroughs in microarchitecture: the way the microprocessor executes applications, in particular, the way it unlocks hidden parallelism within them. Researchers have proposed many exotic microarchitecture enhancements in recent decades, but their commercialization has been stymied because they are too specialized. Strategies that speed-up any application were exhausted long ago. All that remains are strategies that pinpoint specific application behaviors, leading to complex microarchitecture enhancements that perform exceedingly well on some, but not all, tasks. This project fundamentally changes the value proposition of any microarchitecture enhancement. The impacts of this project are: scalable microprocessor performance in the post-Moore era, working closely with industry partners to ensure meaningful results and speed technology transfer, and training students of diverse backgrounds for the workforce.The key idea of the project is to tightly couple the fixed hardware components of a state-of-art microprocessor with reconfigurable (not fixed) hardware components. The fixed hardware still fetches and executes instructions in basically the same way. Enhancements programmed into the reconfigurable hardware intervene to unlock more parallelism in the instruction stream. Different enhancements can be synthesized into the reconfigurable hardware as the task at hand changes. Thus, microarchitecture enhancements are instantly commercializable/deployable. Moreover, taken altogether, the suite of available and future microarchitecture enhancements covers a wide range of application behaviors for acceleration.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

高性能微处理器是所有社会基础设施背后的计算能力。由于半导体技术和制造的限制，他们似乎永无止境的进步，被公众称为“摩尔定律”，已经放缓。 持续的进步需要微架构的突破：微处理器执行应用程序的方式，特别是它解锁其中隐藏的并行性的方式。近几十年来，研究人员提出了许多奇异的微架构增强，但由于过于专业化，它们的商业化一直受到阻碍。加速任何应用程序的策略在很久以前就已经用尽了。剩下的就是精确定位特定应用程序行为的策略，从而导致复杂的微架构增强，这些增强在某些（但不是所有）任务上执行得非常好。这个项目从根本上改变了任何微架构增强的价值主张。该项目的影响是：在后摩尔时代可扩展的微处理器性能，与行业合作伙伴密切合作，以确保有意义的结果和速度的技术转移，并为劳动力培训不同背景的学生。该项目的关键思想是紧密耦合的最先进的微处理器的固定硬件组件与可重新配置（不固定）的硬件组件。固定硬件仍然以基本相同的方式获取和执行指令。编程到可重配置硬件中的增强介入以解锁指令流中的更多并行性。不同的增强可以合成到可重构的硬件作为手头的任务的变化。因此，微体系结构增强是立即可商业化/可部署的。此外，总体而言，现有的和未来的微体系结构增强套件涵盖了广泛的应用程序加速行为。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
