Abstract: The present disclosure discloses a communication method for a slave device connected to a master device via an I2C bus. The method includes detecting the condition of a byte end flag when the slave device is in a transmission mode, and clearing the byte end flag to stop transmitting data to the master device as the slave device is in the transmission mode when the byte end flag is detected to be in a first condition. The first condition indicates all data requested by the master device has been transmitted by the slave device. The present disclosure further discloses a slave device using the above-mentioned communication method. When the slave device is in the transmission mode, it is unnecessary to switch the operation mode of the slave device to stop the slave device from continuing transmitting data when the last byte of data has been transmitted.

Abstract: Improvements over existing data collection interfaces disclosed herein include, among other things, additional logic blocks (and associated timers, state machines, and registers) to off-load data collection and data processing prior to waking a microprocessor from a sleep mode. For example, an improved data collection interface collects a predetermined number of sensor values from a sensor while maintaining active a single communication session with the sensor over a pin of the interface. The microprocessor remains in the sleep mode for an entire duration of the single communication session. The data collection interface can reduce the likelihood of false starts of the microprocessor by using the logic blocks to verify that data meet preconditions prior to interrupting the microprocessor. The data collection interface can reduce the overall power consumption of a chip in which the microprocessor is integrated by a factor of at least about 2× (i.e., 50% reduction in power consumption).

Abstract: Methods and systems for a networked computing system are provided. One method includes generating, based on a first topology, a first proxy endpoint by a first device of a first pluggable compute module; establishing a communication tunnel between the first proxy endpoint and a non-volatile memory express (NVMe) storage device for peer-to-peer communication between the first proxy endpoint of the first device and a controller of the NVMe storage device. An NVMe translation module receives a request for the NVMe storage device from the first proxy endpoint and the NVMe translation module translates the request to an NVMe request for the NVMe storage device for accessing storage space at the NVMe storage device. The method further includes de-allocating the first proxy endpoint, when the first topology is deactivated making the first pluggable compute module and the NVMe storage device available for a second topology.

Abstract: Some examples can enable virtual bridges to be hot plugged into a virtual Peripheral Component Interconnect (vPCI) system. For example, a number of subordinate buses that are connected to a vPCI bridge in the vPCI system can be determined. The vPCI system can be for a virtual machine. A parameter value can then be generated by adding an integer to the number of subordinate buses that are connected to the vPCI bridge. The integer can be a predefined number of additional subordinate buses to enable to be connected to the vPCI bridge. The parameter value can then be assigned to the vPCI bridge. This may enable additional virtual bridges to be hot plugged into the vPCI system at a later time. For example, a new virtual bridge can be added to the vPCI system using the parameter value for the vPCI bridge.

Abstract: A multilayer butterfly network is shown that is operable to transform and align a plurality of fields from an input to an output data stream. Many transformations are possible with such a network which may include separate control of each multiplexer. This invention supports a limited set of multiplexer control signals, which enables a similarly limited set of data transformations. This limited capability is offset by the reduced complexity of the multiplexor control circuits. This invention used precalculated inputs and simple combinatorial logic to generate control signals for the butterfly network. Controls are independent for each layer and therefore are dependent only on the input and output patterns. Controls for the layers can be calculated in parallel.
