We can suppose that result of two multiplications can't be greate of 0xFFFF
|
| 182 |
i.e. is 16-bit, so we use here only PMULLW instruction and can avoid
|
| 183 |
a complex multiplication.
|
| 184 |
=====================================================
|
| 185 |
Full formula for multiplication of 2 integer numbers
|
| 186 |
which are represent as high:low words:
|
| 187 |
input: value1 = high1:low1
|
| 188 |
value2 = high2:low2
|
| 189 |
output: value3 = value1*value2
|
| 190 |
value3=high3:low3 (on overflow: modulus 2^32 wrap-around)
|
| 191 |
this mean that for 0x123456 * 0x123456 correct result is 0x766cb0ce4
|
| 192 |
but this algorithm will compute only 0x66cb0ce4
|
| 193 |
this limited by 16-bit size of operands
|
| 194 |
---------------------------------
|
| 195 |
tlow1 = high1*low2
|
| 196 |
tlow2 = high2*low1
|
| 197 |
tlow1 = tlow1 + tlow2
|
| 198 |
high3:low3 = low1*low2
|
| 199 |
high3 += tlow1
