Data is moved from the registers to the internal memory when it is not being actively used. Data from
- I read a book it says accumulator is a register for doing arithmetic. This Accumulator said. Without a register like an accumulator, it would be necessary to write the result of each calculation (addition, multiplication, shift, etc.) to main memory, perhaps only to be read right back again for use in the next operation.
- The accumulator register is used by the ALU ( arithmetic and logic unit ) to perform the arithmetic and the logical operations performed by the CPU. The ALU operates on the data stored into the accumulator register. After the ALU operation, the processed data is either sent to the main memory RAM or to the output device.

The temporary register holds the data temporarily during the arithmetic or logical operation of the processor. Accumulator stores the final result of the arithmetic or logical operations.
- Accumulator: The accumulator is an 8-bit register (can store 8-bit data) that is the part of the arithmetic and logical unit (ALU). After performing arithmetical or logical operations, the result is stored in accumulator. Accumulator is also defined as register A. Flag registers:
- In the fetch–execute cycle, three major sections of a CPU work together. These are the registers (address register, program counter, instruction register, data registers and accumulator), the ALU and the control unit. All these sections work to the drumbeat of the system clock at billions of times per second.
- The accumulator is the most important general-purpose resister having multiple functions. It is most efficient in data movement arithmetic and logical operations its functions depend on the design of the processor whether the processor is an accumulator-based processor or a general-purpose registers-based processor.

- Though it’s perfectly legal to create an accumulator without a name, e.g. sc.accumulator(0L), it won’t show up in the UI unless you give it a name. This is a constant source of confusion for end users, who don’t know to pass in a name and think that the accumulators aren’t working.
