Abstract: A method of data compression includes obtaining a data set comprising a sequence of data blocks comprising a predetermined number of data items, partitioning said data set into one or more groups each comprising a predetermined number of data blocks, and performing data compression on one or more groups of data blocks. Data compression is performed by associating a control data item with each of said blocks, generating a control vector comprising the control data items assigned to each of said blocks within a group, removing data blocks comprising entirely data items having said specified value, compressing data blocks comprising at least one data item having a value different from said specified value using a fixed-rate compression scheme, providing a compressed data stream comprising said compressed data blocks, and providing an associated control vector stream to enable control of said compressed data stream.
