Methods, systems, and apparatus for implementing low latency interconnect switches between CPU's and associated protocols. CPU's are configured to be installed on a main board including multiple CPU sockets linked in communication via CPU socket-to-socket interconnect links forming a CPU socket-to-socket ring interconnect. The CPU's are also configured to transfer data between one another by sending data via the CPU socket-to-socket interconnects. Data may be transferred using a packetized protocol, such as QPI, and the CPU's may also be configured to support coherent memory transactions across CPU's.

An apparatus and method are described for detecting and correcting data fetch errors within a processor core. For example, one embodiment of an instruction processing apparatus for detecting and recovering from data fetch errors comprises: at least one processor core having a plurality of instruction processing stages including a data fetch stage and a retirement stage; and error processing logic in communication with the processing stages to perform the operations of: detecting an error associated with data in response to a data fetch operation performed by the data fetch stage; and responsively performing one or more operations to ensure that the error does not corrupt an architectural state of the processor core within the retirement stage.
摘要:
A particular message is received at a first ring stop connected to a first ring of a mesh interconnect including a plurality of rings oriented in a first direction and a plurality of rings oriented in a second direction substantially orthogonal to the first direction. The particular message is injected on a second ring of the mesh interconnect. The first ring is oriented in the first direction, the second ring is oriented in the second direction, and the particular message is to be forwarded on the second ring to another ring stop of a destination component connected to the second ring.

A heterogeneous processor architecture and a method of booting a heterogeneous processor is described. A processor according to one embodiment comprises: a set of large physical processor cores; a set of small physical processor cores having relatively lower performance processing capabilities and relatively lower power usage relative to the large physical processor cores; and a package unit, to enable a bootstrap processor. The bootstrap processor initializes the homogeneous physical processor cores, while the heterogeneous processor presents the appearance of a homogeneous processor to a system firmware interface.

A heterogeneous processor architecture is described. For example, a processor according to one embodiment of the invention comprises: a first set of one or more physical processor cores having first processing characteristics; a second set of one or more physical processor cores having second processing characteristics different from the first processing characteristics; virtual-to-physical (V-P) mapping logic to expose a plurality of virtual processors to software, the plurality of virtual processors to appear to the software as a plurality of homogeneous processor cores, the software to allocate threads to the virtual processors as if the virtual processors were homogeneous processor cores; wherein the V-P mapping logic is to map each virtual processor to a physical processor within the first set of physical processor cores or the second set of physical processor cores such that a thread allocated to a first virtual processor by software is executed by a physical processor mapped to the first virtual processor from the first set or the second set of physical processors.

Methods and apparatus for implementing the Intel QuickPath Interconnect® (QPI) protocol over a PCIe interface. The upper layers of the QPI protocol are implemented over a physical layer of the PCIe interface via use of QPI data bit mappings onto corresponding PCIe x16, x8, and x4 lane configurations. A QPI link layer to PCIe physical layer interface is employed to abstract the QPI link, routing, and protocol layers from the underlying PCIe physical layer (and corresponding PCIe interface circuitry), enabling QPI protocol messages to be employed over PCIe hardware. Thus, QPI functionality, such as support for coherent memory transactions, may be implemented over PCIe interface circuitry.
