To perform multiplication using Booth's recoding, you analyze the bits of the multiplier and generate products based on pairs of bits, adjusting the multiplicand accordingly for each step. In Bit-pair recoding, you group the bits of the multiplier into pairs to simplify the multiplication process, resulting in fewer additions and subtractions. Both methods enhance efficiency in binary multiplication, particularly for signed integers. To apply these techniques, you would need to specify the multiplicand and multiplier values for precise calculations.
