Abstract
A multiplier for least significant bit first multiplication of a multiplicand coded on n bits by a multiplier coefficient includes a processor which, for each bit of the decimal part of the multiplier coefficient between the least significant bit and the most significant bit, calculates the sum of rank n+1 obtained from partial products of the bit in question with the n bits of the multiplicand and from corresponding sums calculated for the preceding bit or bits of the multiplier coefficient. This prevents internal overflow of the multiplier.
