A New Fast and, Area-efficient Dual-Quality 4:2 Compressors for Dynamic Accuracy Configurable Multipliers
The main objective of our project is to design dynamic accuracy configurable multipliers using 4:2 compressors.
Here 4:2 compressors are mainly used in order to have the flexibility of switching between exact and approximate modes. In
approximate mode we find the most advantage of having high speed and low power consumption. Using these compressors
we can obtain the parallel multiplication with respective accuracies in their parameters. The efficiencies of these
compressors in a 32-bit dadda multiplier are evaluated by comparing their parameters with approximate multipliers.
Compared to existing model our proposed model is very advantageous in speed, power and area.
