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.
