Abstract :

This Paper Presents An Accuracy-controllable Multiplier That Generates Its Final Product Using A Carry-maskable Adder. The Scheme Can Dynamically Adjust The Carry Propagation Length To Meet Accuracy Requirements. The Approximate Multiplier Consists Of An Approximate Tree Compressor (ATC) And A Carry-maskable Adder (CMA), Which Compress Partial Products Powerefficiently And Provide Accuracy Scalability Using A Simple Carry-masking Technique. The 8x8 Approximate Multiplier Is Implemented In Verilog HDL, Dividing The Design Into Four Stages: Partial Product Generation, Hierarchical Tree Compression, OR-based Summation Of Compensation Vectors, And A Final Addition Using A Hybrid Adder. The Implementation Balances Accuracy, Speed, And Power, Making It Suitable For Energy-efficient Approximate Computing In Image Processing, Machine Learning, And Embedded Signal Processing Applications. Index Terms: - Approximate Multiplier, Accuracy-controllable Multiplier, Carry-maskable Adder (CMA), Approximate Tree Compressor (ATC), Verilog HDL, Hybrid Adder, Truncated OR Logic, Ripple-carry Adder.
