Abstract
An integrated circuit for processing audio signals from a microphone assembly, combinations thereof and methods therefor, including a multi-issue processor configured to execute multiple instructions concurrently and connectable to a memory with a plurality of locations each represented by a corresponding index. Bit-reversal is performed on a sequence of audio data bits stored in memory by concurrently performing a load or store operation related to a first index and determining whether to perform a load operation for a second index.
