  1. Accumulator

    In a computer's central processing unit, an accumulator is a register in which intermediate arithmetic and logic results are stored. Without a register like an accumulator, it would be necessary to write the result of each calculation to main memory, perhaps only to be read right back again for use in the next operation. Access to main memory is slower than access to a register like the accumulator because the technology used for the large main memory is slower than that used for a register. The canonical example for accumulator use is summing a list of numbers. The accumulator is initially set to zero, then each number in turn is read and added to the value in the accumulator. Only when all numbers have been added is the result held in the accumulator written to main memory or to another, non-accumulator, CPU register. An accumulator machine, also called a 1-operand machine, or a CPU with accumulator-based architecture, is a kind of CPU where, although it may have several registers, the CPU mostly stores the results of calculations in one special register, typically called "the accumulator". Historically almost all early computers were accumulator machines; and many microcontrollers still popular as of 2010 are basically accumulator machines.

The New Hacker's Dictionary

  1. accumulator

    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’). Confusingly, though, an ‘A’ register name prefix may also stand for address, as for example on the Motorola 680x0 family. 2. A register being used for arithmetic or logic (as opposed to addressing or a loop index), especially one being used to accumulate a sum or count of many items. This use is in context of a particular routine or stretch of code. “The FOOBAZ routine uses A3 as an accumulator.” 3. One's in-basket (esp. among old-timers who might use sense 1). “You want this reviewed? Sure, just put it in the accumulator.” (See stack.)

The Standard Electrical Dictionary

  1. Accumulator
