In this paper, 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.application/pdf398552 bytesapplication/pdfen-USAngle quantization; Coordinate rotational digital computer; Extended elmentary angle set; Vector rotation; Algorithms; Approximation theory; Computational complexity; Computer aided design; Computer architecture; Integrated circuit layout; Vectors; VLSI circuits; Digital signal processingjournal article10.1109/ICASSP.2001.9411472-s2.0-0034856256http://ntur.lib.ntu.edu.tw/bitstream/246246/2007041910021231/1/00941147.pdf
