Abstract: Search circuitry responsive to a single instruction for undertaking a step of a search of a data array for an extreme value therein, a method of searching a data array to identify an extreme value therein and a location thereof and a single-instruction, multiple-data (SIMD) processing unit incorporating the search circuitry or the method. In one embodiment, the search circuitry includes: a comparison element configured to compare two values in the data array, (2) multiplexers coupled to the comparison element and configured to select a more extreme value of the two values and a location in the data array of the more extreme value and (3) an incrementer configured to increment a counter associated with the search.

Abstract: 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.
