Abstract
An audio decoder 100 for operating on a received compressed audio data stream compressed using an algorithm employing transform encoding and a bit allocation routine. A first processor 200 performs a first set of operations on the received compressed audio data stream including parsing the compressed audio data stream, recovering data fields within the compressed audio data stream, calculating a bit allocation, and passing frequency domain coefficients to shared memory. A second digital signal processor 100b performs a second set of operations on data passed from the first digital signal processor to shared memory including performing inverse transform operations on the data passed from the first digital signal processor.
