1. A signal processing method comprising the steps of: receiving a first signal representing information in compressed form to a processor, the processor having a plurality of registers, the information being compressed using a discrete transform technique; processing whole words of the first signal according to bit length; partitioning at least one of the whole words into a plurality of subwords; inverse discrete transforming each of the plurality of subwords in accordance with decomposition control of the processor for determination of all discrete values associated with the plurality of subwords for the one of the whole words prior to passing another of the whole words to the processor for processing; and concatenating the plurality of subwords using the discrete values for forming the one of the whole words for providing a second signal representing the information in decompressed form.
