NGS: Software Innovations for Liquid Architectures

标题：液体体系结构的软件创新我们建议通过半自动生成部署在可重新配置逻辑中的定制逻辑，将定制逻辑的优势带到低容量但高性能的应用程序中。通过将(硬核或软核)商用处理器与可重构逻辑相结合，应用程序实质上被提供了一种流畅的体系结构，其中计算机指令集的定义和实现、协处理器的功能及其支持结构可以很容易地改变。这些架构更改可以通过为频繁发生的操作提供指令和高效实现、通过更改高速缓存和其他支持结构的大小或策略以及通过在需要时动态地以速度换取节能来提高性能。在适当的软件支持下，Liquid架构可以提高许多应用程序的性能，从高性能的科学计算到低功耗的嵌入式系统。我们的研究旨在开发促进在液态体系结构上执行应用程序所需的软件基础设施和方法，解决以下问题：

TITLE: Software Innovations for Liquid Architectures We propose to bring the advantages of custom logic to low-volume but high-performance applications by semiautomatically generating custom logic, deployed in reconfigurable logic. By coupling (hard-or soft-core) commodity processors with reconfigurable logic, an application is essentially offered a liquid architecture, where the definition and implementation of the computer's instruction set, its coprocessors' functionality, and its supporting structures can be easily changed. These architectural changes can improve performance by supplying instructions and efficient implementations for frequently occurring operations, by changing the size or policies of caches and other supporting structures, and by dynamically exchanging speed for power-savings where required. With proper software support, liquid architectures can improve the performance of many kinds of applications, ranging from high-performance, scientific calculations to low-power, embedded systems. Our research aims to develop the software infrastructure and methodologies needed to facilitate execution of applications on liquid architectures, addressing the following issues:
