Error Compensation Techniques for Fixed-Width Array Multiplier Design - A Technical Survey

摘要

This paper provides a comprehensive review of various error compensation techniques for fixed width multiplier design along with its applications. In this paper, we have studied different error compensation circuits and their complexities in the fixed-width multipliers. Further, we present the experimental results of error metrics, including normalized maximum absolute error (epsilon(max)), normalized mean error (epsilon(mean)) and normalized mean-square error (epsilon(mse)) to evaluate the accuracy of fixed-width multipliers. This survey is intended to serve as a suitable guideline and reference for future work in fixed-width multiplier design and its related research.
