OR, shift Included in hardware units that do arithmetic Binary Numbers Base 2 binary numbers. Two's complement is the scheme used to represent signed numbers. This is not sign and magnitude representation, which would represent a negative number with the same bit pattern as its complement, except for the sign bit.
Subtraction operands with different signs.
OR 8 - 1 Overflow occurs when there is a carry into the sign bit or a borrow out of the sign bit. Can also be stated as when the leftmost retained bit does not equal the sign bit. Jump to routine that handles exceptions mfc0 can be used to copy EPC back to PC, so can jump back and continue execution of program. MIPS does not have a conditional branch to test overflow, but the sequence of instructions on page 223 can test for it. Negative numbers have infinite number of 1s on left.
