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