Generally, this disclosure provides systems, devices, methods and computer readable media for dynamic configuration and enforcement of access lanes to I/O controllers. The System may include a plurality of Input/Output (I/O) controllers and a plurality of lanes. The system may also include a lane mapping module configured to multiplex at least one of the I/O controllers to at least one of the lanes based on a configuration. The system may further include a first processor configured to detect a change request, the change request to modify the configuration from an existing configuration to a new configuration; and a second processor configured to: verify that the new configuration is valid based on a stock keeping unit (SKU) associated with the system; and, if the verification is successful, store the new configuration in non-volatile memory and reset the system.

Dynamic configuration of input/output controller access lanes

The present disclosure is directed to hardware-based inter-device resource sharing. For example, a remote orchestrator (RO) may provide instructions to cause a device to make at least one hardware resource available to other devices. An RO module in the device may interact with the RO and may configure a configuration module in the device based on instructions received from the RO. The configuration module may set a device configuration when the device transitions from a power off state to a power on state. The device may also comprise a processing module to process data based on the device configuration, interface technology (IT) and at least one hardware resource. The interface technology may allow the processing module and the at least one hardware resource to interact. The RO module may configure the IT to allow the at least one hardware resource to operate locally or remotely based on the instructions.

Hardware-based inter-device resource sharing

A transaction processing method is disclosed to solve the issue of multiple producers (software and hardware) and one or more consumers operating in a peer or hierarchical system. The transaction processing method is a deterministic method operable in a system having any number of producers. The producers themselves may be any combination of hardware and software and may be part of peer or hierarchical systems.

Deterministic method to support multiple producers with multiple consumers in peer or hierarchical systems

A method and apparatus for balancing memory access latency and bandwidth is generally described. In accordance with one example embodiment of the invention, a method comprising determining at least one characteristic of a memory request, and selectively leaving an accessed memory page open after a memory access based, at least in part, on the at least one characteristic for the memory request, to balance memory access latency and bandwidth of a subsequent memory request(s).

Methods and apparatus for balancing memory access latency and bandwidth

A host system is provided with one or more host-fabric adapters installed therein for connecting to a switched fabric of a data network. The host-fabric adapter may comprise at least one Micro-Engine (ME) arranged to establish connections and support data transfers, via a switched fabric, in response to work requests from a host system for data transfers; interface blocks arranged to interface the switched fabric and the host system, and send/receive work requests and/or data messages for data transfers, via the switched fabric, and configured to provide context information needed for said Micro-Engine (ME) to process work requests for data transfers, via the switched fabric, wherein the Micro-Engine (ME) is implemented with a pipelined instruction execution architecture to handle one or more ME instructions and/or one or more tasks in parallel in order to process data messages.

Host-fabric adapter having an efficient multi-tasking pipelined instruction execution micro-controller subsystem

A host system is provided with one or more host-fabric adapters installed therein for connecting to a switched fabric of a data network. The host-fabric adapter may comprise at least one Micro-Engine (ME) arranged to establish connections and support data transfer operations via a switched fabric; a serial interface arranged to receive and transmit data packets from the switched fabric for data transfer operations; a host interface arranged to receive and transmit host data transfer work requests from the host system for data transfer operations; a context memory arranged to provide context information necessary for data transfer operations; a doorbell manager arranged to update the context information needed for the Micro-Engine (ME) to process host data transfer requests for data transfer operations; and, a remote key manager arranged to manage remote keys and check the validity of the remote keys which correspond to outstanding data transfer operations.

Methodology and mechanism for remote key validation for NGIO/InfiniBand&#x2122; applications

A host system is provided with one or more host-fabric adapters installed therein for connecting to a switched fabric of a data network. The host-fabric adapter comprises a micro-controller subsystem configured to establish connections and support data transfers via the switched fabric, and a serial interface which provides an interface with the switched fabric. The micro-controller subsystem includes a Micro-Engine (ME) which executes a ME instruction to send source and destination addresses during a control cycle, and interface logic blocks which supply addressed data from designated sources to the Micro-Engine (ME) at the same time for execution of the ME instruction during a data cycle subsequent to the control cycle.

Video data is received from multiple video receptors. This multidimensional video data is converted from the video receptors into a multidimensional audio representation of the multidimensional video data and are the multidimensional audio representation is output using multiple audio output devices. The conversion of the multidimensional video data includes generating a three-dimensional representation of the multidimensional video data, and generating an audio landscape representation with three-dimensional features based on the three-dimensional representation.
