/əˈkyo͞om(y)əˌlādər/
n. 1. Archaic term for a register. On-line use of it as a synonym for register is a fairly reliable indication that the user has been around for quite a while and/or that the architecture under discussion is quite old. The term in full is almost never used of microprocessor registers, for example, though symbolic names for arithmetic registers beginning in A derive from historical use of the term accumulator (and not, actually, from arithmetic).
