    摘要: A system includes a bus shared by a plurality of devices and a logic circuit adapted to segment the bus into a plurality of portions. In one embodiment of the present invention, the system may include a plurality of devices and a first multiplexer logic circuit adapted to select signals from the plurality of devices. A second multiplexer circuit may receive the selected signals from the first multiplexer circuit and transmit the selected signals to chosen ones of the plurality of devices.

    摘要: An processor includes first and second execution cores that operate in an FRC mode, an FRC check unit to compare results from the first and second execution cores, and an error check unit to detect recoverable errors in the first and second cores. The FRC check unit temporarily stores results from the first or second core, and a timer is activated if a mismatch is detected. If the error detector detects a recoverable error before the timer interval expires, a recovery routine is activated. If the timer interval expires first, a reset routine is activated.

    摘要: A method and apparatus for supporting heterogeneous agents in on-chip busses. In one embodiment, the method includes the detection of a bus arbitration event between at least a first bus agent and a second bus agent. In one embodiment, a bus arbitration event is detected when at least the first bus agent and the second bus agent assert their respective bus request signals in a single clock cycle. Once a bus arbitration event is detected, bus ownership may be granted to both the first bus agent and the second bus agent, when the first bus agent and the second bus agent have different grant-to-valid latencies. In the embodiment, heterogeneous bus agents may coexist on a bus without requiring wasted or unused bus cycles following establishment of bus ownership. Other embodiments are described and claimed.

    摘要: In one embodiment, the present invention includes canisters to control storage of data in a storage system including a plurality of disks. Each of multiple canisters may have a processor configured for uniprocessor mode and having an internal node identifier to identify the processor and an external node identifier to identify another processor with which it is to mirror cached data. The mirroring of cached data may be performed by communication of non-coherent transactions via the PtP interconnect, wherein the PtP interconnect is according to a cache coherent protocol. Other embodiments are described and claimed.
