Developments of Approximate Computing: From Algorithm Level to System Level

Low power is one of the critical parameters in the Very Large Scale Integration (VLSI) circuits design. In recent years, approximate computing techniques have improved the design metrics delay, area, and power or energy with a tradeoff inaccuracy. Computational intensive and error-tolerant applications are more suitable to adopt approximation Methods. Approximate computing is an emerging computing paradigm in low power VLSI design. It provides low power consumption at the cost of accuracy. This paper presents an introduction, applications, and developments in approximate computing.
