摘要
A multiply-accumulate unit (MAU) configurable to perform both real and complex multiplication operations, a method of performing a mac operation and a processing unit incorporating the MAU or the method. In one embodiment, the MAU includes: (1) a first multiplier having a first vector input and a first scalar input and configured to multiply a first vector by a first scalar to yield a first product, (2) a second multiplier having a second vector input and a second scalar input and configured to multiply a second vector by a second scalar to yield a second product and (3) an accumulator coupled to the first multiplier and the second multiplier and configured to receive the first and second products.
