Abstract
An n-bit fixed-width multiplier keeps the input-width and output-width the same by truncating the n least significant output bits. In order to reduce the complexity, direct-truncation multipliers omit the half of the partial products corresponding to the truncated part. However, a large truncation error will be introduced. Thus, error compensation, which equals to estimating the carry bits, is required. In this paper, three carry estimation schemes based on the dependency among the partial products and the inputs are proposed. Not only this dependency is investigated, statistical analysis for these estimation approaches is provided. Applying the proposed schemes, at least 84% the truncation error can be reduced
