Detailed explanation-1: -An accumulator is primarily used as a register in a CPU to store intermediate logical or arithmetic data in multistep calculations. For such calculations, it functions as a temporary storage location.
Detailed explanation-2: -The accumulator is an 8-bit register that is a part of arithmetic/logic unit (ALU). This register is used to store 8-bit data and to perform arithmetic and logical operations. The result of an operation is stored in the accumulator.
Detailed explanation-3: -An accumulator is a type of register included in a CPU. It acts as a temporary storage location which holds an intermediate value in mathematical and logical calculations. Intermediate results of an operation are progressively written to the accumulator, overwriting the previous value.
Detailed explanation-4: -Register A is quite often called as an Accumulator. An accumulator is a register for short-term, intermediate storage of arithmetic and logic data in a computer’s CPU (Central Processing Unit).
Detailed explanation-5: -Accumulator. 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.
