In a computer 's central processing unit (CPU), an accumulator is a register in which intermediate arithmetic and logic results are stored.ccess to main memory is slower than access to a register like the accumulator because the technology used for the large main memory is slower (but cheaper) than that used for a register. Early electronic computer systems were often split into two groups, those with accumulators and those without.
Accumulators can also operate as energy sources during normal operation of the system (i.e. cushioning). Accumulators that are weight-or spring-loaded can also be used in industrial applications. For example, a gas-pressurised hydro-pneumatic accumulator, which has a gas-tight separating element, is most commonly used.
