Thanks very much Ian, this makes very true sense now you explained well in
short summary.
Now if we change the same algo to find the Cartesian to polar
conversion.The theory says,
check the Yi for the trig equation selection as we do previously with Zi in
rotation mode,
but what would be the
In brief, (since the CORDIC algorithm is a simple and fun one to simulate
standalone and look at the functions generated as analog waveforms)
The zi input (fed from the DDC/DUC phase accumulator) represents an angle as a
fraction of 2*Pi.
The symmetry of the sin/cos functions is exploited so
Hi Immi. This paper is one of the better overviews of the CORDIC
algorithm in FPGAs: http://www.andraka.com/files/crdcsrvy.pdf
Also, if you search the archives of this list, there are threads regarding
the specific application of the CORDIC algorithm in the USRP FPGA designs.
For example:
