181 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
