CORDIC, What is it? - Signal Processing Stack Exchange
2021年3月1日 · Below is an intuitive explanation to the CORDIC. The CORDIC algorithm, published by Jack Volder in 1959 (Coordinate Rotation Digital Computer), allows rotating a phasor with only shifts and adds and can be used for phasor rotation, trigonometric calculation and computing the magnitude of of a complex phasor without the use of multipliers.

2024年12月24日 · $\begingroup$ Acutually, I am exploring if the CORDIC algorithm (maybe phase detection method) can work well in low SNR conditions compared with frequency divider (applied in the phase-locked loop). More details are comparsion between two …
Fastest way to compute Arctan2 on an FPGA
2022年2月1日 · The CORDIC as depicted below has a range of +/-90°. Extending this to +/-180° is done by a +/-j rotation (which means simply swap I and Q and change the sign). The CORDIC is the algorithm of choice when successive iteration time is available and there are no multipliers.

CORDIC-Taylor-DDS algorithms - Signal Processing Stack Exchange
2021年6月30日 · CORDIC uses LUT and numerical methods. But I don't get high resolution signals. Taylor is fully numerical methods. However if you don't use 48 or 64 bits, you don't get high resolution signals. However DDS works wonder with 64 LUT. However I don't understand that why we use CORDIC or Taylor algorithm for creating sinus signal?
Efficient Magnitude Comparison for Complex Numbers
2019年12月28日 · Figure 9. output from a binary trick to determine the needed CORDIC pseudo-rotation (see source code at the end) for a complex number. For a pair of complex numbers, the larger rotation would need to be chosen. C++ listing: floating point CORDIC magnitude comparison algorithm and testing
CORDIC arctan function with fixed point (i`m using Q15 format)
2007年2月7日 · i`m doing my thesis comparing CORDIC with polynomial in counting arctan with fixed point. I`m using Q15 format now.
methods of computing fixed point atan2 on FPGA
This led to a pretty large amount of LUTs being devoted to this one task. I tried changing the flow to use partially unrolled CORDIC kernels, but then I needed a multiplied clock frequency to execute repeated loops while still maintaining a continuous input/output flow. With this, I …
CORDIC algorithm - Post.Byes
2005年11月14日 · CORDIC is an iterative algorithm for calculating trig functions including sine, cosine, magnitude and phase. It is particularly suited to hardware implementations because it does not require any multiplies.
