Accumulator (computing) - Wikipedia
In a computer's central processing unit (CPU), the accumulator is a register in which intermediate arithmetic logic unit results are stored. 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. Access to main memory is slower than acc…

Accumulator Register - an overview | ScienceDirect Topics
However, most processors have an accumulator register into which the ALU will automatically load the resultand of a processing operation. Many modern microprocessors have a larger number of CPU data registers which can operate as accumulators in complex arithmetic and logic operations.

What is an accumulator in a microprocessor? - Quora
Answer (1 of 5): It's a register which holds one of the operand and mostly stores the result after operation.. Now let's see why such a register is required,. Let's take a binary operation , I.e. one with two operands , say a =b+c. For a cpu to perform this operation, it needs to fetch the opera...

What is the difference between accumulator based cpu …
It's is used to store information which is immediately needed by the processor. Processors are very fast & only register memory can match their speeds. Therefore all the information to & from the processor goes via registers. Accumulator is a register which stores the intermediate results for large computations.

What is an accumulator-based CPU machine?
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".

What is the function of accumulator register in computer?
Main function of Accumulator Register is to store the output which is generated by your system . When CPU (Center Processing Unit) will execute some instruction then it will produce the result, now AC register is needed to store those produced data.
