Abstract:
A processor includes a plurality of subfunctional units provided corresponding to respective slots of one or more pieces of operation result data including a plurality of slots for an SIMD operation; and an enable generating unit configured to, in each of the one or more pieces of the operation result data, compare a value of a predetermined slot with a value of a slot other than the predetermined slot, and disable one or more subfunctional units to which the value equal to the value of the predetermined slot is inputted, and the processor outputs the value of the predetermined slot as the value of the one or more subfunctional units which have been disabled.
