WebNov 5, 2024 · My understanding now is that 8 bit 2 complement code can only represent numbers from -128 to 127, so when I have -12 I can add +12 and I will set the carry and zero flag. The other way would be to add a negative number to -12 that will be equal to a positive 8 bit number(e.g. -12-120), which means I will set my overflow and carry flags.

It is proved that the Carry-in is not equal to Carry-out hence overflow. With the help of above explanation, we can say that the overflow can be detected by the C-in and C-out at MSB (Most Significant Bit), which is described as follows: With the help of above XOR gate, we can easily detect the overflow. http://www.piclist.com/techref/method/math/c-vs-o.htm google scholar h5指標
