What holds the result of most of arithmetic and logic operation?

What holds the result of most of arithmetic and logic operation?

accumulator
The arithmetic logic unit (ALU) performs the arithmetic and logical functions that are the work of the computer. There are other general purpose registers that hold the input data, and the accumulator receives the result of the operation. The instruction register contains the instruction that the ALU is to perform.

What is the name of a register that stores the intermediate results of arithmetic and logic calculations?

the accumulator
Typically, the ALU includes a register that it uses to store intermediate results of calculations. This register is known as the accumulator .

Which register is used to store the results of any operations?

accumulator register
The accumulator register is used to store the system result. All the results will be stored in the accumulator register when the CPU produces some results after processing.

Which holds the result of an operation?

Explanation: The flag register is known as status register it means it holds the information about the results of arithmetic and logical operations the flag register Incorporates the present processor state. The flag register set the 0 and 1 value according to the result of the arithmetic and logic operation.

What is the main function of arithmetic logic unit?

function in digital computer …of a control unit, an arithmetic logic unit (ALU), a memory unit, and input/output (I/O) controllers. The ALU performs simple addition, subtraction, multiplication, division, and logic operations, such as OR and AND. The memory stores the program’s instructions and data.

How many ALU does a CPU have?

The central processor (CPU) consists of two arithmetic logic units (ALU), a parallel logic unit (PLU) and registers.

Is cache a register?

1. Cache is a smaller and fastest memory component in the computer. Registers is a small amount of fast storage element into the processor. Cache memory is exactly a memory unit.

Is accumulator a 16 bit register?

All microprocessors make use of an accumulator register that can supply one number for an action, and where the result of an action will also be stored. The size of the accumulator in terms of bits is used as a measure of the data unit capability of the microprocessor (as 8-bit, 16-bit, 32-bit, 64-bit, and so on).

Which register is a part of ALU?

The W register is a fundamental component of the ALU as it is used in most arithmetic or logic instructions. The W register, shown as an output of the ALU, also forms a feedback loop, as an input into the ALU.

Why is it important to know the function of a register?

It provides faster access to data, instruction, and addresses stored in it for CPU. It handles the storing/retrieving variables accessed repeatedly. It helps in enhancing program performance significantly. Optimized utilization of memory while executing the program.

What is the size of an accumulator register?

Its size is 16 bits and stores an integer, floating-point values, Characters and array of elements small in size. Accumulator Registers (AC): It holds the results of any operation until it is consumed in the next operation by CPU.

Where are the registers located in a computer?

It is typically a tiny memory unit, not part of the main memory of the computer (Random Access Memory (RAM) or Read-only Memory (ROM)) resides in the CPU. They are positioned in the computer hierarchy a level above main memory.

Where does the final result of the statement end up?

It is clear that the final result must end up in A, because the statement says so. But most CPU’s can’t do this calculation without first calculating ( 3 * B ). So where should that value end up? That depends on the type of CPU architecture. In an accumulator architecture the statement would be translated to something like
