Abstract: Systems and methods for decoding are described. A decoder system is configured to retrieve, from the grain array stored within the on-chip memory, noise pixel data associated with at least one reconstructed video pixel. The decoder system is configured to apply noise data to the at least one reconstructed video pixel to generate at least one output video pixel. The noise data is determined based on the noise pixel data.

Abstract: A method includes determining a picture type of a current picture, determining, based on the picture type of the current picture, whether to write the current picture in a dedicated chip memory or whether to write the current picture a non-dedicated system memory, and writing the current picture in the dedicated chip memory or the non-dedicated system memory based on the determining of whether to write the current picture in the dedicated chip memory or whether to write the current picture in the non-dedicated system memory.

Abstract: A method includes generating a plurality of future reference picture lists associated with a plurality of future pictures of a set of pictures, wherein the set of pictures includes a current picture and the plurality of future pictures, and the plurality of future pictures follow the current picture in coding order, determining, based on information derived from the plurality of future reference picture lists associated with the plurality of future pictures, whether to write the current picture in a dedicated chip memory or whether to write the current picture in a non-dedicated system memory, and writing the current picture in the dedicated chip memory or the non-dedicated system memory based on the determination of whether to write the current picture in the dedicated chip memory or whether to write the current picture the non-dedicated system memory.

Abstract: A video coder includes a plurality of processing elements configured to code video data in parallel. The video coder may receive video data, determine a frequency at which the plurality of processing elements are to code the video data based on a largest coding unit (LCU) size, and a tile size, indicate the frequency to the plurality of processing elements, and code the video data at the frequency.
