Using XOR to flip bits and to zero out registers was a commonly used idiom in IBM System 360 Assembly language and right through to System z. You usually learned this by reading others’ code.

[IMSAI Guy] grabbed an obsolete XOR gate and tried a classic circuit to turn it into a frequency doubler.Of course, being an old part, it won’t work at very high frequencies, but the circuit is ...

Existing integrated circuit technology requires four transistors to form a NAND circuit and 12 transistors to form a XOR circuit. By contrast, only ...

Including XOR gates in your functions offers significant benefits by reducing transistor and track counts and increasing testability. As designers, we're used to representing digital functions using ...
