摘要： A deserializer circuit and method convert a serial bit stream into a parallel bit stream according to a parallel grouping. The deserializer and method include alternatingly demultiplexing a serial data stream into first and second bit streams. The first and second bit streams are respectively serially shifted along a first plurality of shift registers and a second plurality of shift registers. A first portion of the first bit stream in the first plurality of shift registers is selected and a second portion of the second bit stream in the second plurality of shift registers is also selected. A parallel group of data in a parallel data stream is formed from the first and second portions.

摘要： A mobile electronic device (102) includes an earphone/microphone port (104), an I/O circuit to receive a modulated data signal from data input devices via the earphone/microphone port (104), and a processor unit (204) programmed to extract data from the modulated data signal. The processor unit (or the I/O circuit) detects connection of a device to an earphone/microphone connector of the mobile electronic device (102) and determines whether the connected device is a data input device. If the connected device is a data input device (106), the processor unit (204) is programmed to extract data from modulated data signals generated by data input device (106).

摘要： A packet structure for a Mobile Display Digital Interface (MDDI) includes a flexible sub-frame length to efficiently transmit large packets. A windowless video stream packet avoids repetitive transmissions of video packets when some parameters are unchanged, saving bandwidth. An enhanced reverse encapsulation packet combines the feature of a separate round trip delay packet with a separate reverse encapsulation packet. A link freeze is used to halt a transmission of a data stream at any point in the transmission and resume the transmission by a host.

摘要： A data Interface for transferring digital data between a host and a client over a communication path using packet structures linked together to form a communication protocol for communicating a pre-selected set of digital control and presentation data. The signal protocol is used by link controllers configured to generate, transmit, and receive packets forming the communications protocol, and to form digital data into one or more types of data packets, with at least one residing in the host device and being coupled to the client through the communications path. The interface provides a cost-effective, low power, bi-directional, high-speed data transfer mechanism over a short-range "serial" type data link, which lends itself to implementation with miniature connectors and thin flexible cables which are especially useful in connecting display elements such as wearable micro-displays to portable computers and wireless communication devices.

摘要： Aspects of adjusting application parameters for interference mitigation are disclosed. In one aspect, a computing device is provided that employs a control system configured to detect and mitigate electromagnetic interference (EMI) generated within the computing device. More specifically, the control system is configured to detect possible EMI conditions and adjust parameters within the computing device to mitigate such EMI. In this manner, the computing device includes an aggressor application and a victim receiver. The control system is configured to analyze performance tradeoffs based on an acceptable performance level of the aggressor application and the performance degradation experienced by the victim receiver. Based on such analysis, the control system is configured to adjust parameters associated with the aggressor application to mitigate the EMI. Thus, the control system provides designers with an additional tool that may reduce the performance degradation of the victim receiver attributable to the EMI.

摘要： System, methods, and apparatuses are described that facilitate a first device to transmit/retransmit a message to a second device. The first device transmits a first message to the second device. The first device then receives a second message and identifies a bit of the second message indicating an originator of the second message. If the bit indicates the first device as the originator of the second message, then the second message is an echo of the first message. Reception of the echo indicates that the second device is in a sleep state. Accordingly, the first device waits for the second device to wake and retransmits the first message to the second device to ensure that any packets lost during the original transmission of the first message (when the second device was asleep) are now retransmitted while the second device is known to be awake.

摘要： In a multi-wire channel that includes at least three wires, each unique wire pair of the multi-wire channel has approximately the same signal propagation time. In this way, jitter can be mitigated in the multi-wire channel for signaling where, for a given data transfer, a differential signal is transmitting on a particular pair of the wires and every other wire is floating. In some implementations, matching of the signal propagation times involves providing additional delay for at least one of the wires. The additional delay is provided using passive signal delay techniques and/or active signal delay techniques.

摘要： Systems, methods, and apparatus for line multiplexed serial interfaces are disclosed. A method performed by a transmitting device includes asserting a stop condition on a wire of a serial data link by driving the wire to a first voltage level for a first period of time that is less than a duration of the stop condition, monitoring the wire after the first period of time, determining that flow-control has been asserted when the wire remains at a second voltage level for a second period of time that exceeds a minimum period of time defined for flow-control pulses and after the first period of time has elapsed, refraining from transmitting data on the wire while flow-control is asserted, and transmitting data on the wire when flow-control is de-asserted.
