Fixed point multiply: a*m times b*m yields (a*b)*m = a*m * b*m / m
In the above, m is the fixed point 1. For example, 65536 for a 16.16 fixed point.
The instruction allows you to multiply a*m by b*m and then divide by m, renormalizing your fixed point result.
Chuck Moore thinks nobody needs floating point because fixed point is sufficient!
