scripts default iconFixed-Point ATAN2 using CORDIC (Scripts) Publisher's description

This demo consists of a m-file script (fixed_point_atan2_using_cordic.m) and a m-file function (atan2_fixpt.m).

This demo consists of a m-file script (fixed_point_atan2_using_cordic.m) and a m-file function (atan2_fixpt.m). The script contains a step-by-step explanation of how a four quadrant arctan can be calculated using a CORDIC (COordinate Rotation DIgital Computer) algorithm. The first part shows the CORDIC algorithm in floating-point double precision, whereas the second part of the m-file explains how to implement the CORDIC in 16-bit fixed-point with bit shifts. The third part shows how to generate C code for the m-file function to speed-up the algorithm.

The m-file function contains an implementation of the CORDIC in Embedded MATLABв„ў compliant m-code. This function can be used to generate C-code or HDL (VHDL or Verilog) in MATLABВ® of SimulinkВ®.

System Requirements:

MATLAB 7.5 (R2007b)
Program Release Status: New Release
Program Install Support: Install and Uninstall
