Detailed explanation-1: -The ALU makes use of accumulators to store the intermediate results. Accumulators: An accumulator is a register in the CPU that stores intermediate results during arithmetic and logical operations.
Detailed explanation-2: -The accumulator can hold one of the two operands during any ALU operation. If we want to add two bytes together, this would just be an example here; one byte would go to the accumulator, and the other in memory or general purpose register. When executed the two numbers serve as the input to the ALU.
Detailed explanation-3: -It is also known as internal storage unit or the main memory or the primary storage or Random Access Memory (RAM). It stores all the data and the instructions required for processing. It stores intermediate results of processing.
Detailed explanation-4: -In a computer’s central processing unit (CPU), the accumulator (ACC in the image below) is a register in which intermediate arithmetic and logic results are stored.
