Multiply (-13)×(-20) using Booths Algorithm.

Welcome to our channel! In today's video, we'll dive into Booth's Algorithm, a powerful technique for binary multiplication, especially useful for two's complement numbers. Let's break it down step by step! Introduction: Brief overview of binary multiplication. Introduction to Booth's Algorithm and its advantages, especially in handling signed numbers. Step-by-Step Explanation: Initialize Variables: Multiplicand (M) Multiplier (Q) Accumulator (A): Start with 0. Q-1: An additional bit initialized to 0. Count: Number of bits in the multiplier. Main Loop: Repeat for the number of bits in the multiplier: Check Last Two Bits (Q₀ and Q-1): If the pair is 10: Subtract M from A. If the pair is 01: Add M to A. Arithmetic Shift Right (ASR): Shift the combined AQ and Q-1 right by one bit. Maintain the sign bit of A. End Condition: After all bits are processed, A and Q together form the final product. Example Walkthrough: Demonstrate the algorithm with a simple example: Multiplicand (M) = 3 (0011) Multiplier (Q) = -4 (1100 in two's complement) Walk through each iteration showing the changes in A, Q, and Q-1. Benefits of Booth's Algorithm: Efficient handling of positive and negative multipliers. Reduces the number of required addition/subtraction operations. Conclusion: Recap the process. Highlight practical applications in computer arithmetic and digital signal processing.
