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.

该项目的目的是研究一个全系统，循环精确的计算机模拟器，该模拟器的运行速度比具有相似精度的最快的当前模拟器快三个数量级。 通过对模拟器进行仔细的分区来实现此类性能，该模拟器允许在可重新配置的硬件中有效地实现最计算的密集型组件。 这种分区还简化并抽象了模拟器，使它们更易于使其更完整和准确。例如，早期的原型靴未修改的Linux。 该项目的目标是（i）构建和评估此类模拟器的实例，（ii）优化构建和使用此类模拟器的工具，以至于可以在高级本科班级中使用它们，并（iii）通过改善分区界面和实施策略来进一步优化此类模拟器的性能。 由于由此产生的模拟器是同时准确，快速和全系统的，因此我们预计，所有自行车精确的计算机模拟器的用户，从学生设计计算机到工程师到工程师到工程师到高级最终用户，希望将其应用于特定的计算机的应用程序，最终会在同一组中使用这些模拟者的形式。 全面的。 我们希望主要通过Web界面传播模拟器和工具的版本，该版本将允许用户指定模拟器并在我们的网站上的Web上运行它。
