Radix -4/-8 Dual Encoder Block for Multiplier Architecture using GDI Technique
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2012, Vol 1, Issue 9
Abstract
A hybrid radix-4/-8 multiplier is proposed for portable multimedia applications that demand high speed and low energy operation. Depending on the input pattern, the multiplier operates in the radix-8 mode in 56% of the input cases for low power, but reverts to the radix-4 mode in 44% of the slower input cases for high speed. For this Radix 4/8 Dual encoder block is designed. Compared to a conventional CMOS radix-4/8 encoder, the proposed radix- 4/8 encoder consumes 43.6% less power, and 46.51% less area and 3.3% less delay time.
