+  a complex multiplication.
+=====================================================
+ Full formula for multiplication of 2 integer numbers
+ which are represent as high:low words:
+ input: value1 = high1:low1
+        value2 = high2:low2
+ output: value3 = value1*value2
+ value3=high3:low3 (on overflow: modulus 2^32 wrap-around)
+ this mean that for 0x123456 * 0x123456 correct result is 0x766cb0ce4
+ but this algorithm will compute only 0x66cb0ce4
+ this limited by 16-bit size of operands
+ ---------------------------------
+ tlow1 = high1*low2
+ tlow2 = high2*low1
+ tlow1 = tlow1 + tlow2
+ high3:low3 = low1*low2
