摘要： Techniques for utilizing processor cores include sequestering processor cores for use independently from an operating system. In at least one embodiment of the invention, a method includes executing an operating system on a first subset of cores including one or more cores of a plurality of cores of a computer system. The operating system executes as a guest under control of a virtual machine monitor. The method includes executing work for an application on a second subset of cores including one or more cores of the plurality of cores. The first and second subsets of cores are mutually exclusive and the second subset of cores is not visible to the operating system. In at least one embodiment, the method includes sequestering the second subset of cores from the operating system.

摘要： Systems and methods are provided that utilize either non-shared page tables (270) or shared page tables (340) to allow an accelerator device (290, 390) to share physical memory (250, 350) of a computer system (210, 310) that is managed by and operates under control of an operating system (220, 320). The computer system (210, 310) can include a multi-core central processor unit (230, 330). The accelerator device (290, 390) can be, for example, an isolated core processor device (230, 330) of the multi-core central processor unit (230, 330) that is sequestered for use independently of the operating system (220, 320), or an external device that is communicatively coupled to the computer system (210, 310).
摘要翻译：提供了利用非共享页表（270）或共享页表（340）来允许加速器设备（290,390）共享计算机系统（210,310）的物理存储器（250,350）的系统和方法，），其由操作系统（220,320）的控制下操作和操作。计算机系统（210,310）可以包括多核心中央处理器单元（230,330）。加速器装置（290,390）可以是例如多核中央处理器单元（230,330）的隔离的核心处理器设备（230,330），其被隔离用于独立于操作系统（220,390） 320）或通信地耦合到计算机系统（210,310）的外部设备。

摘要： Embodiments allow a smaller, simpler hardware implementation of an input/output memory management unit (IOMMU) having improved translation behavior that is independent of page table structures and formats. Embodiments also provide device-independent structures and methods of implementation, allowing greater generality of software (fewer specific software versions, in turn reducing development costs).
摘要翻译：实施例允许具有独立于页表结构和格式的改进的翻译行为的输入/输出存储器管理单元（IOMMU）的更小，更简单的硬件实现。实施例还提供了与设备无关的结构和实现方法，允许更大程度的软件通用性（较少的特定软件版本，从而降低开发成本）。
