Abstract
An embodiment of the present invention is a mixed length encoding unit. The mixed length may be a 12/16 bits (12/16-b) encoding algorithm within a multiply-accumulate (MAC). The mixed length encoding unit includes 16-b Booth encoder adapted to produce eight partial product vectors from sixteen bits of data. The 16-b Booth encoder is coupled to a four stage Wallace Tree. During a first cycle of the invention, a multiplex system directs the eight partial products and an accumulation vector to a four stage Wallace Tree. During subsequent cycles, the multiplex system directs six partial product vectors, an accumulation vector, one carry-feedback input vector, and one sum-feedback input vector to the four stage Wallace Tree.
