Designing an 8-Bit Multiplier in Verilog: From Logic to Implementation

Multiplication is a fundamental arithmetic operation in digital signal processing (DSP), microprocessors, and embedded systems. While software programmers take multiplication for granted, hardware engineers must carefully consider the trade-offs between speed (latency) and area (resource usage) when designing a multiplier.

module multiplier #(parameter WIDTH = 8) (
    input [WIDTH-1:0] a, b,
    output [2*WIDTH-1:0] product
);
    assign product = a * b;
endmodule

module multiplier_8bit ( input [7:0] a, input [7:0] b, output [15:0] product ); // Continuous assignment using the '*' operator assign product = a * b; endmodule Use code with caution. Copied to clipboard

Why use Booth?

Dadda Multiplier: Similar to Wallace, but it optimizes the reduction stages slightly differently to save on hardware area while maintaining high speed.
