    Good Evening all.

    I am currently in the process of designing a Soft Decision 16 QAM (quadrature amplitude modulation) for a DVB-T system.

    I am looking to take two 8 bit inputs (x and y coordinates) and find out how far it is from another location (fixed point). This creates a triangle, hence my desire for Pythagoras.

    Is this possible in VHDL (realistically)?

    Regards

    Dave

    You can feed the two 8-bit values into a 16-bit look up table and get your answer out.
