I guess it would be TTL what you feel?

What logic is used contained by our PC's CPU?

Common logic implementation technique used in CPU design include:



unstructured impulsive logic

finite state machines

microprogramming (common from 1965 to 1985, no longer common except for CISC CPUs)

programmable logic array (common within the 1980s, no longer common)



As for electronic design and logic, I think tis RTL.
i would envision it depends on who made it. and what the proccess is ie.. adding, subtracting, multiplication and so on. though i regard as that it's a combination of bollean, TTL.
