Overview
The Xilinx LogiCORE™ CORDIC IP implements a generalized coordinate rotational digital computer (CORDIC) algorithm, initially developed by Volder to iteratively solve trigonometric equations, and later generalized by Walther to solve a broader range of equations, including the hyperbolic and square root equations. The CORDIC IP implements the following equation types:
* Rectangular <-> Polar Conversion
* Trigonometric
* Hyperbolic
* Square Root
* Rectangular <-> Polar Conversion
* Trigonometric
* Hyperbolic
* Square Root
Key features
- Rectangular <-> Polar Conversion
- Trigonometric
- Hyperbolic
- Square Root

Implementing matrix inversions in fixed-point hardware
We implement fixed-point matrix inversion on a Virtex-4 FPGA using a synthesizable QR-decomposition MATLAB model and the AccelDSP Synthesis tool. The resulting function occupies 12% of a XC4VSX55 device and has a 1.7 MSPS data rate.
