NK		 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
187 value2 = high2:low2
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 ---------------------------------
194 tlow1 = high1*low2
195 tlow2 = high2*low1
196 tlow1 = tlow1 + tlow2
197 high3:low3 = low1*low2
198 high3 += tlow1
