When does the overflow flag in 8086 set?
In the 8086/8088, the overflow flag is set when the result of an arithmetic instruction exceeds the bounds of the signed representation of a number. This is not the same as the carry flag, which is used for the unsigned representation. Both flags get set as needed. You decide which one to pay attention to.
What is overflow bit in register?
In Computerprocessors, the overflow flag (sometimes called Vflag) is usually a single Bitin a system Status_registerused to indicate when an Arithmetic_overflowhas occurred in an operation.
Difference between carry flag and overflow flag in 8086?
The carry flag indicates that an arithmetic operation between two numbers resulted in an unsigned carry or borrow. The overflow flag indicates that an arithmetic operation between two numbers resulted in an unexpected change in sign, i.e. an overflow. Carry is also like overflow. The difference is in interpretation. Do you consider the numbers signed or unsigned? Its all in interpretation because the hardware logic needed to add two numbers works the same, no matter if they are considered signed or unsigned. Both flags are set or cleared together, so you can use whichever you wish.
What is meant by flag is set or not set in 8085 processor?
The flags are testable conditions that are set after many arithmetic or logical instructions to indicate something about the result of the result. For instance, the Z flag means the result is zero, the N flag means it is negative, the O flag means a signed overflow occurred, the C flag means an unsigned overflow occurred, and the P flag means an even number of bits is set in the result. You can use the various flag testable jump instructions, such as JZ or JNZ to test the flag after performing an operation that sets or resets the flag.
How do you stop stack overflow line 160?
restart your computer, it will clear the overcommitted stack
The different types of FLAGS register?
There are a huge number of different FLAG registers. The most common are zero flag (Z), carry flag (C), sign flag/ negative flag (S/N), and overflow flag (V/O/W). Each flag contains different information about the state of the processor.

Explain 8086 flag register?
FLAGS REGISTER="h2headingh3"style="color:rgb(0,0,0);"name="flags_register">Flags Register - determines the current state of the processor. They are modified automatically by CPU after mathematical operations and allow one to determine the type of the result as well as determine conditions to transfer control to other parts of the program. Generally you cannot access these registers directly.Carry Flag (CF) - this flag is set to 1 when there is an unsigned overflow. For example when you add bytes 255 + 1 (result is not in range 0...255). When there is no overflow this flag is set to 0.Parity Flag (PF) - this flag is set to 1 when there is even number of one bits in result, and to 0 when there is odd number of one bits.Auxiliary Flag (AF) - set to 1 when there is an unsigned overflow for low nibble (4 bits).Zero Flag (ZF) - set to 1 when result is zero. For non-zero result this flag is set to 0.Sign Flag (SF) - set to 1 when result is negative. When result is positive it is set to 0. (This flag takes the value of the most significant bit.)Trap Flag (TF) - Used for on-chip debugging.Interrupt enable Flag (IF) - when this flag is set to 1 CPU reacts to interrupts from external devices.Direction Flag (DF) - this flag is used by some instructions to process data chains, when this flag is set to 0 - the processing is done forward, when this flag is set to 1 the processing is done backward.Overflow Flag (OF) - set to 1 when there is a signed overflow. For example, when you add bytes 100 + 50 (result is not in range -128...127).
How do you clear the marked for improvement flag on Answers.com?
To clear the marked for improvement banner, that appears above answers that have been voted as not answering the question, you will need to make a change to the answer (not a minor edit) and then the flag will automatically clear and the votes will reset. The flag can take a while to go away, sometimes up to 2 days.

Carry flag and over flow flag in 8051?
Carry flag is the the bit 7 of the 8 bit PSW register, whenever there is an addition or subtraction process that has a carry on its 7th bit, the carry flag (C/CY) will be set to 1. OV is set to 1 when there is an arithmetic overflow. this applies to signed and unsigned operations.
