Carry Flag Vs Overflow Flag at Violet Romero blog

Carry Flag Vs Overflow Flag. In computer processors the carry flag (usually indicated as the c flag) is a single bit in a system status register/flag register used to indicate. In computer processors, the overflow flag (sometimes called the v flag) is usually a single bit in a system status register used to indicate. If there is a carry out from bit 3 on addition, or a borrow into bit 3 on subtraction, af will be 1. Otherwise, af will be 0. If there is a carry out from the most significant bit (msb) on addition, or there is a borrow into the msb on subtraction, cf will be 1. The carry flag (c) the carry flag is perhaps the most versatile and frequently used flag in the 8051 arsenal. The isa says that the carry flag is set when the operation is unsigned, and overflow is set when the operation is signed. The carry bit handles overflow due to the result size exceeding the register. Otherwise, cf will be 0. While related in the context of arithmetic flags, the carry and overflow bits are fundamentally different: The ov flag represents the overflow into bit 7, while the cy flag represents the overflow into bit 8, so for a signed operation,. Let’s examine each flag in detail:
