The document discusses various multiplier architectures, including array, tree-based, and 6-bit Wallace multipliers. It highlights the use of Booth encoding for signed binary multiplication, emphasizing its efficiency, particularly in handling consecutive binary digits. A 6-bit Wallace tree multiplier is presented, alongside comparisons with journal references.

Booth encoding • Usedfor multiplication of signed binary numbers • Product is represented in 2’s complement notation • Handles both positive and negative multipliers uniformly • Number of Addition operations greatly reduce when there are consecutive 1’s or 0’s in the multiplier • Worst case is when there are pairs of alternate 0’s and 1’s either 01 or 10 in the multipliers so that maximum of additions and subtractions are required.
