A common hardware engine that performs the frequency to time domain transform for both MPEG and Dolby AC3 audio standards is presented. An integral part of the dual mode audio decoder, the cost-effective approach taken here requires minimal computation steps with due consideration on control, address generation, data pipelining, and the overall hardware structure.
