ABSTRACT:
A method of processing exponent data in an audio decoder. A first block of audio data is received including encoded exponent data. The encoded exponent data is packed into packed encoded words and stored in memory. Exponents are generated from the packed encoded words in memory for processing the first block of audio data. A second block of audio data is received. A determination is made as to whether a reuse flag has been set for the second block, and if the reuse flag has been set, exponents are generated from the packed encoded words memory for processing the second block of data.
