Abstract
This work presents a Field Programmable Gate Array (FPGA) prototyping of a new low latency pipelined COordinate Rotation DIgital Computer (CORDIC)-like rotator. The proposed rotator predicts the directions for all rotations in parallel and determines the final coordinates using the architecture with logarithmic relation between the number stages and precision of the target angle. The functionality of the pipelined CORDIC-like rotator is verified by implementing on the Xilinx Virtex-4 pro device (XC4vlx40, 90 nm technology). Based on detailed comparisons with the available pipelined rotators for the resolution of 8–12 bits, it is observed that the proposed rotator requires less hardware and improves latency by 45–85%. © 2016 Informa UK Limited, trading as Taylor & Francis Group.
