Title
Enhanced scaling-free CORDIC
Abstract
Coordinate Rotation DIgital Computer (CORDIC) rotator is a well known and widely used algorithm within computers due to its way of carrying out some calculations such as trigonometric functions, among others. A scale factor compensation inherent to the CORDIC algorithm becomes an important drawback when trying to improve its benefits, although some authors have come up with a new scaling-free version, which has been successfully implemented within wireless applications. However, this new CORDIC can still be significantly improved by modifying some of its parts, therefore, this paper shows an enhanced version of the scaling-free CORDIC. These new enhancements have been implemented and tested, obtaining some new architectures which are able to reach a 35% lower latency and a 36% reduction in area and power consumption compared to the original scaling-free architecture.
