  1. accumulator

    An accumulator is a storage device or register in a computer or calculator where intermediate arithmetic and logic results are stored. It plays a crucial role in improving the processing speed by reducing the need to access main memory for frequently used data. Also, in the energy industry, an accumulator refers to a device that stores energy or fluid power for conversion into controlled motion.

  2. accumulator

    An accumulator is a type of register, storage or location in a computer or digital system that collects and holds data or values, often for the purpose of arithmetic or logical operations. This process typically involves accumulating, or adding up, consecutive numbers or values to achieve a total sum. The term can also be used in various other fields, like hydraulics or mechanics, to refer to a device that accumulates energy or fluid.

  3. accumulator

    An accumulator is a type of register in a computer's CPU that collects and stores data temporarily during processing. It gathers and holds intermediate results before these are moved to the computer's memory storage. Alternatively, in the context of machinery or engineering, an accumulator can refer to an apparatus that collects energy or fluid and stores it for gradual release when needed.

Webster Dictionary

  1. Accumulatornoun

    one who, or that which, accumulates, collects, or amasses

  2. Accumulatornoun

    an apparatus by means of which energy or power can be stored, such as the cylinder or tank for storing water for hydraulic elevators, the secondary or storage battery used for accumulating the energy of electrical charges, etc

  3. Accumulatornoun

    a system of elastic springs for relieving the strain upon a rope, as in deep-sea dredging

  4. Etymology: [L.]


  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 Nuttall Encyclopedia

  1. Accumulator

    a hydraulic press for storing up water at a high pressure; also a device for storing up electric energy.

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.)
