ABSTRACT:
A distributed arithmetic multiply/accumulate (MAC) unit for computing inverse discrete cosine transformations (IDCTs). In one embodiment, the distributed arithmetic MAC unit includes: (1) a first pipeline stage configured to perform dot products on received sequential input data and (2) a second pipeline stage coupled to the first pipeline stage and configured to compute additions and subtractions of the dot products to yield sequential output data.
