To date, its implementation is still restricted by complexity of performing addition and subtraction functions as a result of using large lookup tables. In this paper, a method is revealed to substantially reduce these tables by means of using second order co-transformation procedure. The results predominantly show that the proposed technique offers significantly better speed, area and accuracy than current state-of-the-art logarithmic number system. 2014-04-07T14:53:27Z 2014-04-07T14:53:27Z 2013 Article Procedia Engineering, vol. 53, 2013, pages 387-392 978-162748634-7 18777058 http://www.sciencedirect.com/science/article/pii/S1877705813001690 http://dspace.unimap.edu.my:80/dspace/handle/123456789/33472 en Elsevier Ltd.
