Analysis of power–accuracy trade‐off in digital signal processing applications using low‐power approximate adders

Low Power Digital Image Processing Using Approximate Adders

Low power is one of the emerging trend in the field of VLSI which can be used in portable multimedia devices employing various signal processing algorithms and architectures. In most multimedia applications, human beings can gather useful information from slightly erroneous outputs. Therefore, we do not need to produce exactly correct numerical outputs. So we are using different approximate add...

Transformational Design of Digital Signal Processing Applications

In the design of modern digital systems, such as image processing systems, it is, because of their complexity, of great importance that correctness is guaranteed during the design. Transformational design is a method that integrates guaranteed correctness into the design process. Correctness-by-construction is obtained by applying local behavior-preserving transformations —which have themselves...

Low-Power Digital Filtering Using Approximate Processing

We present an algorithmic approach to the design of low-power frequency-selective digital filters based on the concepts of adaptive filtering and approximate processing. The proposed approach uses a feedback mechanism in conjunction with wellknown implementation structures for finite impulse response (FIR) and infinite impulse response (IIR) digital filters. Our algorithm is designed to reduce ...

Optimization of Power and Area in Digital Signal Processing using Approximate Multiplier

To reduce power utilization and area are some of the most important criteria for the fabrication of Digital Signal Processing and high performance systems. Optimizing the speed and area of the multiplier is a major design issue. In most of the multiplication, the multiplier is an energyhungry component. To improve energy efficiency of multipliers, the choice of multiplier is very important. Her...
