How to determine overflow from an adder/subtractor?

WebIn 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 … WebAug 25, 2014 · The ALU can use full carry-lookahead (like the 8008) or can even be half-sized (like the Z-80). The incrementer can be a performance problem because it is typically 16 bits in an 8-bit processor, resulting in twice the ripple delay. The incrementer can have ripple carry (8085), one carry lookahead (6502) or several carry lookahead stages (Z-80). man with unlimited airline ticket
