Flag in microprocessor
WebRegisters receive binary data as input, checks the data available with them and process the input and deliver the output to the system as binary output. Now, a copy of the output is stored in the register. This helps the system to fetch the data for faster processing. Registers are classified based on their functionality and behavior.

WebOverflow flag. In computer processors, the overflow flag (sometimes called the V flag) is usually a single bit in a system status register used to indicate when an arithmetic overflow has occurred in an operation, indicating that the signed two's-complement result would not fit in the number of bits used for the result. WebIn signed arithmetic, the carry flag tells you nothing interesting. Overflow Flag. The rules for turning on the overflow flag in binary/integer math are two: If the sum of two numbers with the sign bits off yields a result number with the sign bit on, the "overflow" flag is turned on. 0100 + 0100 = 1000 (overflow flag is turned on)
