I need to multiply 2 vectors (dot product) v1*v2 of real numbers
using asm in ATMega8535.
The first one is chosen based on a external variable value x (real number varying between 0 and 100), that is:

if 1<x<2 then v1=[a b c]
if 2<x<3 then v1=[d e f]
.
.
.
v1's values a,b,c,d...are known.

Can anyone help me plz?

TY
