Abstract: Various embodiments of methods and systems for managing compressed data transaction sizes in a system on a chip ("SoC") in a portable computing device ("PCD") are disclosed. Based on lengths of compressed data tiles associated in a group, wherein the compressed data tiles are comprised within a compressed image file, multiple compressed data tiles may be aggregated into a single, multi-tile transaction. A metadata file may be generated in association with the single multi-tile transaction to identify the transaction as a multi-tile transaction and provide offset data to distinguish data associated with the compressed data tiles. Using the metadata, embodiments of the solution may provide for random access and modification of the compressed data stored in association with a multi-tile transaction.

Abstract: An apparatus configured to decode a block of video data in a coded bitstream includes a memory and a processor in communication with the memory. The memory is configured to store data associated with the block of video data in the coded bitstream. The processor is configured to: determine a transform partition type of the block, the block associated with transform coefficients determined via applying one or more transform functions on a plurality of pixel values associated with the block; determine, based on the transform partition type, an order in which the transform coefficients are to be inputted to an inverse transform function corresponding to the one or more transform functions; obtain output values via inputting the transform coefficients to the inverse transform function in the determined order; and decode the block of video data in the coded bitstream based on the output values.
