Computer hardware with native support for large-bitwidth operations can be used for the concurrent calculation of multiple independent linear image processing operations when these operations map integers to integers. This is achieved by packing multiple input samples in one large-bitwidth number, performing a single operation with that number and unpacking the results. We propose an operational framework for tight packing, i.e., achieve the maximum packing possible by a certain implementation. We validate our framework on floating-point units natively supported in mainstream programmable processors. For image processing tasks where operational tight packing leads to increased packing in comparison to previously-known operational packing, the processing throughput is increased by up to 25%. © 2010 IEEE.
