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. WebSep 9, 2024 · 3. I am designing a 16 bit ALU in verilog based on an existing RISC ISA. The ISA says that the carry flag is set when the operation is unsigned, and overflow is set when the operation is signed. The interesting thing is that the ISA implements ADD and SUB instructions that operate on both signed and unsigned numbers.
