Abstract
A data packer forma bit stream for forwarding values to memory. The bit stream includes the values and respective prefixes for identifying the values and the data packer is configured to insert the prefixes at predetermined boundaries in the bit stream, such that a prefix for identifying one value is inserted between bits that define a value identified by a preceding prefix. A data unpacker unpacks a bit stream that comprises values and respective prefixes for identifying those values that are located at predetermined boundaries in the bit stream, such that a prefix for identifying one value is inserted between bits that define a value identified by a preceding prefix. The data unpacker identifies a prefix at a predetermined boundary in the bit stream and determine, in dependence on that prefix and the predetermined boundaries, a location of the next prefix in the bit stream.
