| We can suppose that result of two multiplications can't be greater than 0xFFFF |

| ===================================================== |
| 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 |
