Abstract	Vector rotation is the key operation employed extensively in many digital signal processing applications. We introduce a new design concept called angle quantization (AQ). It can be used as a design index for vector rotational operation, where the rotational angle is known in advance. Based on the AQ process, we establish a unified design framework for cost-effective low-latency rotational algorithms and architectures. Several existing works, such as conventional CORDIC, AR-CORDIC, MVR-CORDIC, and EEAS-based CORDIC, can be fitted into the design framework, forming a vector rotational CORDIC family. Based on the new design framework, we can realize high-speed/low complexity rotational VLSI circuits, whereas without degrading the precision performance in fixed-point implementations.
