Abstract

This paper presents high-radix CORDIC algorithms for high-speed sine and cosine computation. Since the CORDIC calculation takes O(n) steps for evaluating a function in n-bit precision, significant reduction of processing latency is required for real-time signal processing applications. In this paper, we present a unified approach to low-latency CORDIC implementation based on high-radix algorithms, and propose `radix-2-4-8 CORDIC processor', which achieves low-latency computation by changing radix during execution.
