Abstract

We propose a novel hybrid logarithmic approximate multiplier HYLO, which combines Radix-4 Booth encoding and logarithm product approximation for partial product generation. With this, HYLO brings the advantages of two major strategies: truncated multipliers and logarithm product approximation. Due to the smaller number of partial products, the described multiplier is power-efficient and can be employed in a wide area of error-resilient applications without the decrease in performance or quality.
