The goal of this project is to research a full-system, cycle-accurate computer simulator that runs approximately three orders of magnitude faster than the fastest current simulators of similar accuracy. Such performance is achieved by a careful partitioning of the simulator that permits the most computationally intensive component to be efficiently implemented in reconfigurable hardware. This partitioning also simplifies and abstracts the simulators, making them easier to make more complete and accurate. For example, an early prototype boots unmodified Linux. The goals of this project are to (i) build and evaluate instances of such simulators, (ii) refine tools to build and use such simulators to the point that they could be used in an advanced undergraduate class and (iii) to further optimize the performance of such simulators by improving the partition interface and implementation strategies. Since the resulting simulators are simultaneously accurate, fast and full-system, we anticipate that all users of cycle-accurate computer simulators, ranging from students to architects designing computers to engineers developing the computers to advanced end-users who wish to tune their applications for a particular computer, will eventually use a form of such a simulator.Sharing the same infrastructure will likely lead to better communication between these groups, resulting in better computer systems overall. We expect to disseminate versions of the simulators and tools primarily through a web interface that will allow users to specify a simulator and run it over the web at our site.

该项目的目标是研究一个全系统，周期精确的计算机模拟器，运行速度比类似精度的最快电流模拟器快约三个数量级。 这样的性能是通过仔细划分的模拟器，允许最计算密集的组件，以有效地实现可重构硬件。 这种划分还简化和抽象了模拟器，使它们更容易更完整和准确。例如，早期的原型引导未修改的Linux。 这个项目的目标是（一）建立和评估这种模拟器的实例，（二）完善工具，建立和使用这种模拟器的点，他们可以在一个先进的本科类和（iii），以进一步优化这种模拟器的性能，通过改进分区接口和实现策略。 由于生成的模拟器同时准确、快速且全系统，我们预计周期准确计算机模拟器的所有用户，从学生到设计计算机的建筑师，再到开发计算机的工程师，再到希望调整其应用程序的高级最终用户针对特定计算机，最终将使用这种模拟器的形式。共享相同的基础设施可能会导致这些团体之间更好的沟通，从而导致整体上更好的计算机系统。 我们希望主要通过网络界面传播模拟器和工具的版本，该界面允许用户指定模拟器并在我们的网站上运行它。
