摘要： A method and apparatus for enhancing/extending a serial point-to-point interconnect architecture, such as Peripheral Component Interconnect Express (PCIe) is herein described. Temporal and locality caching hints and prefetching hints are provided to improve system wide caching and prefetching. Message codes for atomic operations to arbitrate ownership between system devices/resources are included to allow efficient access/ownership of shared data. Loose transaction ordering provided for while maintaining corresponding transaction priority to memory locations to ensure data integrity and efficient memory access. Active power sub-states and setting thereof is included to allow for more efficient power management. And, caching of device local memory in a host address space, as well as caching of system memory in a device local memory address space is provided for to improve bandwidth and latency for memory accesses.

摘要： Method, apparatus, and systems employing dictionary-based high-bandwidth lossless compression. A pair of dictionaries having entries that are synchronized and encoded to support compression and decompression operations are implemented via logic at a compressor and decompressor. The compressor/decompressor logic operatives in a cooperative manner, including implementing the same dictionary update schemes, resulting in the data in the respective dictionaries being synchronized. The dictionaries are also configured with replaceable entries, and replacement policies are implemented based on matching bytes of data within sets of data being transferred over the link. Various schemes are disclosed for entry replacement, as well as a delayed dictionary update technique. The techniques support line-speed compression and decompression using parallel operations resulting in substantially no latency overhead.

摘要： A method, system, and apparatus may route an interrupt to a first core of a plurality of cores of a multi-core system. If the first core is in an idle or low power state, or operating in a power state at or below a threshold power state, a core in a least idle state may be found. The interrupt may be rerouted to and processed by the core in the least idle state. Cores in a multi-core system may be rated based on for example, power states or other characteristics, and interrupts may be assigned based on these ratings. Other embodiments are described and claimed.

摘要翻译： 方法，系统和装置可以将中断路由到多核系统的多个核心的第一核心。 如果第一核心处于空闲或低功率状态，或处于等于或低于阈值功率状态的功率状态，则可以找到处于最小空闲状态的核心。 中断可以在最不空闲状态下由核心重新路由到并处理。 可以基于例如功率状态或其他特性对多核系统中的核进行额定，并且可以基于这些额定值分配中断。 描述和要求保护其他实施例。
