WebBitwise Ops Computer Organization I 3 CS@VT August 2009 ©2006-09 McQuain, Feng & Ribbens Bitwise AND The MIPS andinstruction simply ANDs the bits of the two source registers and stores the resulting bits in the destination register. 1101 1010 AND 1011 0011 ---> 1001 0010 The andoperation yields 1 iff both the source bits are 1: The AND instruction is used for supporting logical expressions by performing bitwise AND operation. The bitwise AND operation returns 1, if the matching bits from both the operands are 1, otherwise it returns 0. For example − The AND operation can be used for clearing one or more bits. For example, say the BL … See more The OR instruction is used for supporting logical expression by performing bitwise OR operation. The bitwise OR operator returns 1, if the … See more The TEST instruction works same as the AND operation, but unlike AND instruction, it does not change the first operand. So, if we need to check … See more The XOR instruction implements the bitwise XOR operation. The XOR operation sets the resultant bit to 1, if and only if the bits from … See more The NOT instruction implements the bitwise NOT operation. NOT operation reverses the bits in an operand. The operand could be either in a register or in the memory. For example, See more

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: WebUses for Logical Operators " Finally, note that BICing a bit with 1 resets the bit (sets to 0) at the output while BICing a bit with 0 produces the original bit. " This can be used to force certain bits of a
