Product Description
The 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
Key Features and Benefits
- Functional configurations
- Optional coarse rotation module to extend the range of CORDIC from the first quadrant (+Pi/4 to - Pi/4 Radians) to the full circle
- Optional amplitude compensation scaling module to compensate for the output amplitude scale factor of the CORDIC algorithm
- Output rounding modes: Truncation, Round to Pos Infinity, Round to Pos/Neg Infinity, and Round to Nearest Even
- Word serial architectural configuration for small area
- Parallel architectural configuration for high throughput
- Control of the internal add-sub precision
- Control of the number of add-sub iterations
- X and Y data formats: Signed Fraction, Unsigned Fraction, and Unsigned Integer
- Phase data formats: Radian, Pi Radian
- Fully synchronous design using a single clock
