Hi,
I read an article on division using LUT. It says:
"Since b is a 16-bit number (used in 1.15 format), there are (2^15 −1) = 32767 different values of 1/b. "
That is, it uses 16-bit data, but has 32767 different values. I cannot make it through, as it only needs 15-bit is enough. Can you give me an explanation about it?
Thanks,
