We can suppose that result of two multiplications can't be greate of 0xFFFF

i.e. is 16-bit, so we use here only PMULLW instruction and can avoid

a complex multiplication.

Full formula for multiplication of 2 integer numbers

which are represent as high:low words:

input: value1 = high1:low1

value2 = high2:low2
|
||||
output: value3 = value1*value2
|
||||
value3=high3:low3 (on overflow: modulus 2^32 wrap-around)
|
||||
this mean that for 0x123456 * 0x123456 correct result is 0x766cb0ce4
|
||||
but this algorithm will compute only 0x66cb0ce4
|

this limited by 16-bit size of operands
