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
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
---------------------------------
197
tlow1 = tlow1 + tlow2
198
high3:low3 = low1*low2
