WebA bitwise XOR is a binary operation that takes two bit patterns of equal length and performs the logical exclusive OR operation on each pair of corresponding bits. The result in each position is 1 if only one of the bits is 1, but will be 0 if both are 0 or both are 1. ... Assembly language programmers and optimizing compilers sometimes use XOR ... WebBitwise Addition & Multiplication. Bitwise Operations, is the logical operations between two binary digits or change the value of individual bit based on the bitwise logic of the operator. For example, the bitwise AND & OR operations represents multiplication (logical AND) & addition (logical OR) operation between the binary digits respectively.

WebTo multiply a sixteen bit number by two, we first LSL the lower byte, then ROL the high byte, this has the net effect of "rolling" the high bit of the lower byte into the first bit of the 2nd byte. This technique can be expanded to multiply even larger numbers. Multiplying a 32-bit number by two:
