Abstract: 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.

Abstract: Embodiments of the present invention provide a resource management mechanism to monitor the availability of resources, detect the cause of a rejection, distinguish between different types of rejections, and manage the different types accordingly. For example, a queue manager in accordance with embodiments of the invention may be able to classify rejected requests, for example, as either a “long reject” or a “short reject” based on the cause of the rejection and the amount of time the rejection conditions are expected to remain valid. A short reject request may be rescheduled in an appropriate service queue, while a long reject request may be suspended in a reject queue. Other features are described and claimed.

Abstract: Briefly, a system and a method to efficiently track changes in memory or storage areas, for example, in cache memories of computers and electronic systems. A method in accordance with an exemplary embodiment of the invention includes, for example, updating a tracking list with an address and/or a corresponding address to be updated of a changed entry in an intermediate memory. A system in accordance with an exemplary embodiment of the invention may include, for example, a tracking unit to track the locations of potential data discrepancies between a reference memory and an intermediate memory.

Abstract: A cache management logistics controls a transfer of a trace. A first cache couples to the cache management logistics to evict the trace based on a replacement mechanism. A second cache couples to the cache management logistics to receive the trace based on a number of accesses to the trace.

Abstract: In an embodiment, a method includes receiving a binary of a program code. The binary is based on a first instruction set architecture. The method also includes translating the binary, wherein the translated binary is based on a combination of the first instruction set architecture and a second instruction set architecture.

Abstract: Some embodiments of the invention provide devices, systems and methods of cache coherence. For example, an apparatus in accordance with an embodiment of the invention includes a memory to store a memory line; and a cache controller logic to assign a first cache coherence state to the memory line in relation to a first component, and to assign a second, different, cache coherence state to the memory line in relation to a second, different, component.

Abstract: Embodiments of the invention provide a method that includes partitioning a series of instructions of a trace into a plurality of dependency sets before executing the trace; and marking a first group of the dependency sets as critical and a second group of the dependency sets as non-critical Embodiments of the invention also provide a method that may identify a dependency set in the second group, which delays the execution of at least one dependency set in the first group, as a delaying dependency set; counting the number of delays caused by the delaying dependency set; and re-marking the delaying dependency set as critical when a predefined delaying event threshold is reached.

Abstract: A distributed system is provided for apportioning an instruction stream into multiple segments for processing in multiple parallel processing units, and for merging the processed segments into a single processed instruction stream having the same sequential relative order as the original instruction stream. Tags may be attached to each segment after apportioning to indicate the order in which the various segments are to be merged. In one embodiment, the end of each segment includes a tag indicating the unit to which the next instruction in the original instruction sequence is directed.

Abstract: Systems and methods of managing processors provide for detecting a command at a core of a processor having a plurality of cores, where the command requests a transition of the core to an idle state. Power consumption of the core is managed based on the command and an idle state status of each of the plurality of cores.
