摘要： Quality of Service (QoS) mechanisms and facilities are introduced into USB-based wireless Local Area Networking (LAN) communication systems. Techniques are provided for managing multiple priority queues in USB-based wireless communications systems, and for ensuring that lower priority traffic is not precluded from accessing the medium during sustained periods of use by high(er) priority traffic. A method is provided to resolve Quality of Service issues in emerging high-speed USB-based communications systems by offering support for multiple queue management within the system. A further embodiment provides an escalation mechanism for the purposes of mitigating low priority class data starvation in these communications systems, when it becomes an issue. QoS initiatives escalate a lower priority traffic class for the purposes of mitigating low priority class data starvation of the present invention, and/or use a single data buffer with management techniques to temporarily block or flow control data on a lower priority channel.

摘要： In one embodiment, a Universal Serial Bus (USB) system assigns a first priority level to a first USB endpoint and a second priority level that is lower than the first priority level to a second USB endpoint. The USB system has memory that stores first USB data packets corresponding to the first priority level and second USB data packets corresponding to the second priority level. The USB system also has a controller that manages transfers of (i) the first USB data packets to the first USB endpoint and (ii) the second USB data packets to the second USB endpoint. If the memory concurrently stores first and second USB data packets, then the controller determines an order for transferring the first and second USB data packets based on the second priority level being lower than the first priority level and/or detection of a starvation condition for the second endpoint.

摘要： In described embodiments, a transceiver includes a clock and data recovery module (CDR) with an eye monitor and a cycle slip monitor. The cycle slip detector monitors a CDR lock condition, which might be through detection of slips in sampling and/or transition timing detection. The cycle slip detector provides a check point to sense system divergence, allowing for a mechanism to recover CDR lock. In addition, when the CDR is out-of-lock, the various parameters that are adaptively set (e.g., equalizer parameters) might be invalid during system divergence. Consequently, these parameters might be declared invalid by the system and not used.

摘要： Methods and apparatus are provided for clock skew calibration in a clock and data recovery system. One aspect of the invention compensates for skew among a plurality of clocks in a clock and data recovery system. The clocks are applied to a plurality of latches to sample an incoming signal. A reference signal, such as a Nyquist signal, is applied to a data input of each of the latches. Statistics of “early” and “late” corrections applied to at least one of the clocks by a bang-bang phase detector in the clock and data recovery system are evaluated and a delay of a clock buffer associated with the at least one clock is adjusted to obtain approximately a 50% early-to-late ratio for the at least one clock. The clock and data recovery system ensures that the early-to-late ratio for the sum of the plurality of clocks is approximately 50%.
