  • Rotational/Vector mode CORDIC
    • Performs either complex vector rotation using rotating angle, or polar-to-cartesian transformation
    • The input angle, complex vector ports, and the number of iterations are parametrized.
    • MATLAB model is parametrized accodingly
    • Fully pipelined with an initial latency of #of iterations+3
  • CORDIC
    • Functions supported:
    • Input data widths from 8 to 32 bits
    • Configurable number of iterations used to derive output from 4 to 32
    • Optional pre-rotation module

    • Rectangular <-> Polar Conversion
    • Trigonometric
    • Hyperbolic
    • Square Root
  • NCO Intel® FPGA IP Core
    • A numerically controlled oscillator (NCO) is a digital signal generator, which synthesizes a discrete-time, discrete-valued representation of a sinusoidal waveform
    • You can typically use NCOs in communication systems
    • In such systems, they are used as quadrature carrier generators in I-Q mixers, in which baseband data is modulated onto the orthogonal carriers in one of a variety of ways.
