Good day. I know this has been discussed a lot, but each situation seems different. I want to implement trigonometry functions on a Fixed Point FPGA. Can you please assist me with...

Look up tables are the way to go if you have few input/output bit.

In case 8 bit input and 8 bit input you get 256 byte of memory that is more than reasonable.

With 16/16 you get 128Kb of memory, that starts to be difficult in a low cost FPGA.
