carrier_mixer_xs HDL Worker

HDL implementation using a numerically controlled oscillator (NCO) for the carrier generator, which uses the CORDIC algorithm to generate an approximation of sine and cosine.

Detail

Worker Properties

• extend_amplitude_range: The carrier_amplitude default value of 14060 ensures an overflow on the output is not possible. Setting extend_amplitude_range to true extends the internal bit-widths by 1 for a larger carrier_amplitude without internal overflow (at the cost of additional FPGA resource).
