Abstract: RISC-V (Reduced Instruction Set Computing) is a high-performance Instruction Set Architecture (ISA) capable of performing CISC level functions. ALUs form the fundamental execution unit of any processor. The conventional ALU’s are designed using the combinational circuits like the adders, subtractors, multipliers, decoders etc.... Also, they are designed in such a way that it calculates the result each time for the selected operation and then assigns it to the output signal. This leads to more delay (because the operands are calculated only at that instant) and the increased computational complexity. The proposed multiplexer based ALU focuses on power optimization and reduces the delay in the execution of the processor which results in improved performance of the processor. Multiplexers are used instead of other combinational circuits where it uses the registers to store the intermediate results and for selecting the corresponding output signal based on the selected operation on the same data. Hence the ALU designed using these multiplexers will have less delay when compared to the conventional ALU’s.
