Nettet9. mar. 2015 · A binary pattern stored as a 16-bit value x in Q2.14 format represents the value x/2 14, therefore if we have A and B then. So if you directly multiply the patterns A and B, you need to divide the result by 2 14 to get it back into the form x/2 14 like this. Output = A*B >> 14; A rounding step is needed to get the nearest value.
