Abstract: A method and apparatus to perform a multi-field matching search. A search unit groups single fields of a multiple-field source into a search target having multiple-field keys (MFKs) whose single fields correspond to the single fields in multiple-field vectors (MFVs) of entries in a data structure. The search unit generates a set of queries based, at least in part, on the MFKs, where each query has a different MFK as a lead MFK. The search unit determines, based, at least in part, on a query, whether the non-wildcard values in the MFVs of an entry match the non-wildcard values in corresponding MFKs of the search target.

Abstract: A method and apparatus for hardware-base edge handling in video post-processing. In one embodiment, the method includes the identification of at least one unstored input pixel required to compute an output pixel during output pixel computation. Once identified, a pixel value is generated for the at least one unstored input pixel according to a detected edge handling mode.

Other implementations are also disclosed.

Abstract: According to some embodiments, a resource is allocated in accordance with a masked request vector. For example, a masking unit may receive a request vector and provide a masked request vector, wherein each bit in the request vector represents a requestor and indicates if that requestor is requesting a resource. A first priority encoder may receive the masked request vector from the masking unit and output a signal indicating a selected requestor. According to some embodiments, a second priority encoder may receive the un-masked request vector and output a signal indicating an alternate selected requestor.
