We can suppose that result of two multiplications can't be greater than 0xFFFF
181
i.e. is 16-bit, so we use here only PMULLW instruction and can avoid
182
a complex multiplication.
183
=====================================================
184
Full formula for multiplication of 2 integer numbers
185
which are represent as high:low words:
186
input: value1 = high1:low1
188
output: value3 = value1*value2
189
value3=high3:low3 (on overflow: modulus 2^32 wrap-around)
190
this mean that for 0x123456 * 0x123456 correct result is 0x766cb0ce4
191
but this algorithm will compute only 0x66cb0ce4
192
this limited by 16-bit size of operands
193
---------------------------------
196
tlow1 = tlow1 + tlow2
197
high3:low3 = low1*low2
