GENERATING DELTA UPDATES FOR A PROCESSING DEVICE

摘要

A method of generating a delta update for updating memory content of a storage medium of a processing device from a current version to an updated version of the memory content, the storage medium being arranged to have stored the memory content organised as memory sectors, the processing device being arranged to address the stored memory content as pages of memory content, each page being mapped to a respective location in the storage medium. The method comprises: determining a change of content in a first sector from the current version to the updated version; determining at least a first page including said change, the first page being mapped to the first sector; generating update instructions for causing the processing device to store updated memory content fo the first page in a second sector; generating update instructions for causing the processing device to remap the first page to the second sector.
