The Cordic algorithm is an iterative algorithm based on vector rotations over elementary angles. The algorithm normally operates in one of two modes. In rotation mode, it rotates a vector (x 0 , y 0 ) in the Cartesian plane over an input angle z 0 . MyHDL is an open source, pure Python package. Install with pip and enjoy the Python ecosystem immediately. Visit the project on Github. Release news.

Aug 28, 2013 · The Fast Fourier Transform (FFT) is one of the most important algorithms in signal processing and data analysis. I've used it for years, but having no formal computer science background, It occurred to me this week that I've never thought to ask how the FFT computes the discrete Fourier transform so quickly.

I am coding a QR decomposition algorithm in MATLAB, just to make sure I have the mechanics correct. Here is the code for the main function: function [Q,R] = QRgivens(A) n = length(A(:... DATA_WIDTH is the input/output data width of the CORDIC which has a range of 8 to 16. The input clock frequency is the sample rate of the samples. The amplitude of the complex wave is runtime con gurable via the magnitude property. An enable input is available to either enable (true) or bypass (false) the circuit.

You can use the VHDL-extras library files piecemeal with no tools other than the simulator or synthesizer you will process them with. If you wish to use the provided Modelsim build scripts you will need Modelsim, Python 2.x, sed, grep, and GNU make. To run the test suite you will need Python 2.7 and Modelsim.

Those 2 posts have now been downvoted into oblivion. This is now the top post even though it has nothing to do with the original question. Now people have to scroll through this meta conversation of complaints about how people are hostile and not helpful in order to get to the other top posts, which are now actually quite friendly and helpful. The Cordic algorithm is an iterative algorithm based on vector rotations over elementary angles. The algorithm normally operates in one of two modes. In rotation mode, it rotates a vector (x 0 , y 0 ) in the Cartesian plane over an input angle z 0 . Author: Yi-Hsiang Lai (seanlatias @ github) COordinate Rotation DIgital Computer (CORDIC) is a method for calculating a variety of functions including trigonometric and hyperbolic. The various functions are calculated through an iterative set of vector rotations. The Cordic algorithm is an iterative algorithm based on vector rotations over elementary angles. The algorithm normally operates in one of two modes. In rotation mode, it rotates a vector (x 0 , y 0 ) in the Cartesian plane over an input angle z 0 .

Impressive algorithmic technology from yesteryear. Computes cosine, sine, tangent, hypoteneuse, and arctangent using only simple scaled integer arithmetic (a few constants, bit shifts, sign flips, and integer adds in the inner loop and one scaled-multiply in the outer loop).

Projects I have worked in past on wear leveling in resistive memories (LPDDR2-NVM and DDRx), energy estimation of DDR3 DRAMs, FPGA based FIB lookups in Named Data Network and several hobby projects hosted at my GitHub profile.

Cordic is notoriously inaccurate when you get to the 7th digit or so, and unpredictable. Secondly, i heard there is a bug in their implementation, which causes even more problems. I took a look at the sin function for linux gcc, and sure enough, it uses chebyshev. the built-in stuff isn't used. GitHub Gist: star and fork alejolp's gists by creating an account on GitHub.
