    Abstract: A device for implementing a rate-distortion optimization (RDO)-based small transform coefficients suppression algorithm includes a processing module, a control block, and a switch. The processing module may be configured to process a prediction residual associated with a transform unit (TU) of a video frame and to generate a number of coefficients and a processed output. The control block may be configured to receive the coefficients and to generate a control signal based on the plurality of coefficients. The switch may be configured to select, as an output of the device, one of the processed output or an output of a zero-out block based on the control signal. The zero-out block may be configured to assign a zero value to each of the plurality of coefficients of the TU to suppress small transform coefficients.

    Abstract: A transmitter's operation is characterized using components having relatively low cost and low complexity. A device includes comparator(s) that compare a transmitter's analog output to predetermined level(s) to generate count(s) associated with analog output range bin(s). Each of the predetermined levels is associated with a corresponding one of the analog output range bins. A transfer function of the transmitter is generated using the comparison count values associated with the analog output range bin(s). A histogram may be generated from the comparison count values associated with the various analog output range bins. An equalizer is implemented to process data that will be transmitted by the transmitter. The equalizer uses equalizer parameter(s) that are selected based on the characterization of the transmitter (e.g., its transfer function, its histogram, etc.). The equalizer may use default or start up parameters until the transmitter's operation is characterized.

    Abstract: Embodiments provide systems and methods for a probabilistic reporting mode, where an Optical Network Unit (ONU) sends a REPORT message only when it has data to transmit. The absence of a REPORT message from an ONU is treated by the Optical Line Terminal (OLT) as indicating absence of data to transmit at the ONU. In another aspect, embodiments include systems and methods for an unsolicited burst mode, where an ONU can be configured to transmit data in the upstream in an unsolicited manner. The unsolicited burst mode includes mechanisms to ensure that no data is lost due to potential collisions between ONUs.

    Abstract: A system includes a pre-trigger buffer and a post-trigger buffer for recording entries related to specific network element. Buffer management monitoring circuitry captures entries leading up to a trigger criterion being met in the pre-trigger buffer and entries following the trigger criterion being met in the post-trigger buffer. The trigger criterion may include network element status, such as a threshold queue level; or an event, such as a dropped packet. The pre-trigger buffer may include a circular buffer in which older entries are overwritten by newer entries. Once the trigger condition is met, the pre-trigger buffer contents are held while the post-trigger buffer fills. Once the post-trigger buffer fills, the contents of the buffers may be read.
