- We can suppose that result of two multiplications can't be greater than 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
- ---------------------------------
- tlow1 = high1*low2
- tlow2 = high2*low1
- tlow1 = tlow1 + tlow2
- high3:low3 = low1*low2
- high3 += tlow1
