PROJECT TITLE :

A Low-Power High-Speed Accuracy-Controllable Approximate Multiplier Design - 2018

ABSTRACT:

Multiplication may be a key elementary perform for several error-tolerant applications. Approximate multiplication is taken into account to be an efficient technique for trading off energy against performance and accuracy. This paper proposes an accuracy-controllable multiplier whose final product is generated by a carry-maskable adder. The proposed theme can dynamically choose the length of the carry propagation to satisfy the accuracy necessities flexibly. The partial product tree of the multiplier is approximated by the proposed tree compressor. An eight×eight multiplier design is implemented by employing the carry-maskable adder and also the compressor. Compared with a conventional Wallace tree multiplier, the proposed multiplier reduced power consumption by between 47.threep.c and fifty six.a pair of% and important path delay by between twenty nine.9percent and 60.fivep.c, depending on the specified accuracy. Its silicon area was additionally 44.half-dozen% smaller. In addition, results from a picture processing application demonstrate that the standard of the processed pictures can be controlled by the proposed multiplier design.
