<p>A multiplier array is modified to perform interpolations. The interpolations use a normalized first operand A between 0 and 1. The interpolation is the function B*A+C*(1-A). Standard multipliers accept two operands as inputs, but interpolations require 3 operands (A, B, C). The AND gates in Booth encoders (30) in a standard multiplier array are replaced by multiplexers. Each multiplexer selects a bit from one of the two operands (B or C) based on a bit of the first operand A. The interpolate operation multiplies the first operand A by the second operand B while simultaneously multiplying the bit-wise inverse of the first operand A' by the third operand C.</p> |
