Let the multiplicand be ( A = A_7A_6...A_0 ) and multiplier be ( B = B_7B_6...B_0 ). The product ( P = A \times B ) is computed as: 8 bit array multiplier verilog code

The top-level module instantiates rows of adders. For example, the first product bit

// Final product generation assign P[15:8] = pp7[7:1], pp6[7:1], pp5[7:1], pp4[7:1], pp3[7:1], pp2[7:1], pp1[7:1], pp0[7:1]; module half_adder(input a, b, output s, c); assign

// Assign product bits assign P[1] = sum[0][0]; assign P[2] = sum[1][1]; assign P[3] = sum[2][2]; assign P[4] = sum[3][3]; assign P[5] = sum[4][4]; assign P[6] = sum[5][5]; assign P[7] = sum[6][6]; assign P[8] = final_sum[0]; assign P[9] = final_sum[1]; assign P[10] = final_sum[2]; assign P[11] = final_sum[3]; assign P[12] = final_sum[4]; assign P[13] = final_sum[5]; assign P[14] = final_sum[6]; assign P[15] = final_sum[7];

High regularity makes it easy to layout in VLSI, but it uses more area than serial multipliers. Speed/Delay Higher latency compared to Baugh-Wooley For example, the first product bit // Final

Example parameterizable header:

// full_adder.v module full_adder ( input a, b, cin, output sum, cout ); assign sum = a ^ b ^ cin; assign cout = (a & b) | (b & cin) | (cin & a); endmodule
