    Abstract: A method and apparatus for enabling compression of a stream of pictures according to a target bit rate are described. A first configuration parameter for a first portion is determined based at least in part on a first relative weight of the first portion with respect to a first set of N portions, where the first set of N portions includes the first portion and N-1 portions which succeed the first portion. A second configuration parameter for a second portion of a second picture is determined based at least in part on a second relative weight of the second portion with respect to a second set of M portions of pictures, where the second set of M portions includes a subset of the N-1 portions from the first set and zero or more additional portions of pictures from the stream of pictures.

    Abstract: Method and apparatus of compressing a stream of pictures in parallel in a compression device, where the compression device includes at least a first and a second component, are described. A first portion of a first picture of a stream of pictures is processed in the first component of the compression device, while a second portion of a second picture of the stream of pictures is simultaneously processed in the second component of the compression device according to partial compression statistics associated with the second picture, where the partial compression statistics result from the processing of the second picture in the compression device when compression of the second picture is not yet completed.

    Abstract: A method of memory management using a page table is provided where the method supports memory pages having a plurality of page sizes including a first page size and a second page size, where the second page size is a multiple (N) of the first page size. If the page table does not include an entry for a memory page of the first page size, the method includes reducing a size of the page table by eliminating at least one of a plurality of sections of the page table.

    Abstract: In accordance with one embodiment a graphics processing system is configured to switch from a processing of a primitive associated with a first context to a processing of a command list associated with a second context where the primitive includes a plurality of regions. The system includes a plurality of processing modules and at least one module of the plurality of processing modules is configured to receive a request to switch to the second context. In one embodiment, the plurality of processing modules includes a first module that is configured to, following a receipt of the request by the at least one module, to complete a processing of at least one region selected from among the plurality of regions before interrupting the processing of the primitive prior to completion and processing at least a part of the command list associated with the second context; and a second module configured to provide data concerning the primitive to the first module following a processing of the primitive by the second module. The graphics processing system may also include a memory configured to save a state of the second module, where the state corresponds to the state of the second module when processing the primitive associated with the first context.
