This article provides a comprehensive evaluation of recently proposed approximate arithmetic circuits mainly including adders, multipliers, and dividers; they are compared under different design constraints and applied to image processing and deep learning applications.
By J.-M. Muller
This article presents classical approaches of approximate elementary functions with the mainstream techniques of shift-and-add algorithms, polynomial or rational approximations, table-based methods, and bit manipulation.
By S. Amanollahi, M. Kamal, A. Afzali-Kusha, and M. Pedra
This article reviews the circuit-level techniques for both approximate logic and memory blocks.
By M. Traiola, A. Virazel, P. Girard, M. Barbareschi, and A. Bosio
This article examines the test procedure of approximate integrated circuits by identifying the main approximation-aware testing phases.
By I. Scarabottolo, G. Ansaloni, G. A. Constantinides, L. Pozzi, and S. Reda
This article reviews the transformation methods for functional approximation, which can achieve an approximate Boolean function from its exact designs.
By W. Liu, C. Gu, M. O’Neill, G. Qu, P. Montuschi, and F. Lombardi
This article focuses on an emerging area that links security and approximate computing.
By S. Venkataramani et al.
