Abstract: An apparatus for decoding a current block in a scan order identifies a current entropy coded transform coefficient from the current block; determines, based on the scan order and using a scan order distance table, a first scan order distance that is a difference between a first scan order location corresponding to the current entropy coded transform coefficient and a second scan order location corresponding to a first context coefficient; identifies, using the first scan order distance, a first location into a context coefficient register; identifies, at the first location of the context coefficient register, a first context coefficient value; identifies a probability distribution using at least the first context coefficient value; entropy decodes the current entropy coded transform coefficient using the probability distribution to obtain an entropy decoded current transform coefficient; and includes the entropy decoded current transform coefficient in an output video stream.

Abstract: Systems, methods, and apparatuses for coding using efficient context handling in arithmetic coding. Efficient context handling in arithmetic coding may include identifying a scan order for a current block and entropy decoding a current entropy coded transform coefficient from the current block, which may include determining, based on the scan order, a first scan order distance between a scan order location corresponding to the current entropy coded transform coefficient and a scan order location corresponding to a first context coefficient, identifying a first context coefficient value from a first location in a context coefficient register, the first location corresponding to the first scan order distance, wherein the context coefficient register is a reduced size context coefficient register, and entropy decoding the current entropy coded transform coefficient based on the first context coefficient value.

Abstract: A non-transitory computer-readable storage medium having stored thereon computer executable program code which, when executed on a computer system, causes the computer system to perform steps is disclosed. The steps include receiving a portion of a source code including a first program model defining an element of an integrated circuit, generating a first register-transfer level (RTL) description based on the portion of the source code, defining a library component based on the first RTL description, receiving the source code including a second program model defining the integrated circuit, replacing the portion of the source code corresponding to the first program model with the library component, and generating a second RTL description based on the source code.

Abstract: Systems and methods are provided herein relating to decoding and encoding. A decoder component concurrently decodes coefficient blocks from separate data streams received. A stream decoder initiates the decoding process and provides coefficient data downstream to a single decoding pipeline. The stream decoder includes a plurality of sub stream decoders with associated buffers that enable decoding coefficients of a macroblock concurrently in a single processing pipeline. The sub stream decoders receive different sub-partitions of the macroblock from different data streams of encoded video data. The decoder component is thus operable to concurrently decode the sub-partitions, which are received from separate data streams, within a single decoding pipeline.
