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 |
|
--------------------------------- |
|
tlow1 = high1*low2 |
|
tlow2 = high2*low1 |
|
tlow1 = tlow1 + tlow2 |
|
high3:low3 = low1*low2 |
|
high3 += tlow1 |
