High-Performance Asynchronous Computer and SoC Architecture

这项研究致力于开发用于异步高性能计算机的电路和体系结构。与我们计划利用的传统全局同步方法相比，异步组织具有许多显著的优势。这些优势可以分为两大类：与异步电路的电路级属性相关的优势，以及与这种实现形式的更高级别时序属性相关的优势。电路优势主要与没有全局时钟信号直接相关，包括更低的电磁干扰(EMI)、更低的功率，以及由于异步系统部件的本地和模块化互连而更容易的系统集成。更高级别的组织优势包括异步系统能够适应系统组件中依赖数据的延迟，利用系统活动的提前完成，以及在系统操作期间更自然地调停子任务并发。

This research is focused on developing circuits and architectures for asynchronous high-performance computers. Asynchronous organization has a number of significant advantages over the traditional globally synchronous approach that we plan to exploit. These advantages can be broken down into two general categories: those that relate to the circuit-level properties of asynchronous circuits, and those that relate to the higher-level sequential properties of this form of implementation. Circuit advantages, which are mostly directly related to the absence of the global clock signal, include lower electro-magnetic interference (EMI), lower power, and easier system integration due to the local and modular interconnection of asynchronous system pieces. Higher-level organizational advantagesinclude the ability of an asynchronous system to adapt to data-dependent delays in system components, take advantage of early completion of system activities, and more naturally mediate sub-taskconcurrency during system operation.
