摘要：
A digital signal processing circuit having a pre-adder circuit includes; a first register block and a pre-adder circuit coupled to a multiplier circuit and to a set of multiplexers, where the set of multiplexers are controlled by an opcode, and where the pre-adder circuit has a first adder circuit; and an arithmetic logic unit (ALU) having a second adder circuit and coupled to the set of multiplexers.
