    Abstract: A system and method is provided for traffic management and regulation in a packet-based communication network, the system and method facilitating proactive, discriminating congestion control on a per flow basis of packets traversing the Internet via use of a Weighted Random Early Detection (WRED) algorithm that monitors the incoming packet queue and optimizes enqueuing or discard of incoming packets to stabilize queue length and promote efficient packet processing. During optimized discard conditions, the system and method discern a relative priority among incoming packets, distribute packets with a relatively high priority and discard packets with a relatively low priority. Additionally, packet traffic are policed and discarded according to packet type, quantity or other predetermined criteria. The present invention performs in periodic mode, demand mode or both, and can be implemented as a hardware solution, a software solution, or a combination thereof.

    Abstract: The present invention provides a unique system and method for optimizing packet processing flow in a communications network by minimizing latency associated with packet-forwarding eligibility determinations. The present invention employs a speculative scheme with automatic recovery, including a two-way multithreaded implementation designed to overcome the aforementioned latency issue, including the functionality of enqueuing an incoming packet in both packet memory and a cut through buffer; determining the packet's eligibility for cutting through the buffer; and based on the determination, rolling back the unsuccessful process.

    Abstract: Techniques related to stereo image correspondence are discussed. Such techniques may include determining a filtered cost volume for stereo images using phase domain based costs and selecting disparity values for pixel locations based on the filtered cost volume. The filtered cost volume may be generated based on phase matching costs in single or multi-resolution.

    Abstract: A floating point arithmetic apparatus for converting numbers between an integer format and a floating point format, wherein a conversion operation requires a greater data path width than a conversion operation. The apparatus comprises right shift circuitry that receives a number in the floating point format, wherein the right shift circuitry includes additional register positions to accommodate a shift beyond a data path width required by an arithmetic operation.
