ABSTRACT:
An Integrated Circuit (IC) having a single-instruction-multiple-data (SIMD) is disclosed. The SIMD circuit includes: a plurality of multiplexers controlled by a first opcode; and an arithmetic logic unit (ALU) coupled to the plurality of multiplexers and controlled by a second opcode; and wherein the ALU has a plurality of adders, where the plurality of adders are controlled by some bits of the second opcode, and where a first adder of the plurality of adders adds a plurality of input bits to produce first summation bits and a first carry bit; the first adder operating concurrently with the other adders of the plurality of adders.
