Generalised-CORDIC

A generalised CORDIC architecture which can calculate a variety of functions like sinx, arctan(x), hyperbolic fuctions and a lot more.

Some specifics about the code

• We have used synthesizable 32 bit fixed point number format out of which 16 are fraction bits(after decimal).
• There are six modes:
  • Mode 0: Circular Rotation Mode
  • Mode 1: Circular Vector Mode
  • Mode 2: Linear Rotation Mode
  • Mode 3: Linear Vector Mode
  • Mode 4: Hyperbolic Rotation Mode
  • Mode 5: Hyperbolic Vector Mode
• At one time, only one mode can be used. To use a mode, comment out the rest of the modes in testbench.
• The code uses same hardware for all the modes, making it quite efficient.
• There are two inputs. For linear mode, both inputs are used and for circular and hyperbolic modes, one input is used.
• For outputs, see either of X, Y or Z depending on the particular mode.
• Post synthesis and implementation simulations are verified in Vivado Design Suite.
