Abstract: A general input/output communication port implements a communication stack that includes a physical layer, a data link layer and a transaction layer. The transaction layer includes assembling a packet header for a message request transaction to one or more logical devices. The packet header includes a format field to indicate the length of the packet header and to further specify whether the packet header includes a data payload, a subset of a type field to indicate the packet header relates to the message request transaction and a message field. The message field includes a message to implement the message request transaction. The message includes at least one message that is selected from a group of messages.

Abstract: Systems and methods for long-term non-volatile non-rotating optical storage of digital information rely on storage elements that include optical storage media, an access subsystem configured to access bits of information from one of the storage elements, and a support structure configured to support multiple storage elements. A laser used to retrieve and/or record bits of digital information may be moved along two orthogonal dimensions while the storage element is non-rotating.

Abstract: A storage device is provided to maintain a value of flow control credits allocated for a device on a channel and flow control logic is provided to receive a flow control signal over a link of an interconnect, the flow control signal indicating flow control credits allocated for the device on the channel. The flow control logic is further to update the value of flow control credits based on activity of the device on the channel.

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.
