What is ALU result?
The ALU Result is the address to access memory and is placed in the ALUOut internal register. The next state depends on whether the opcode indicates if the instruction was a load or a store. State 3. This state is used for load instructions.
Where are the results of a calculation by the ALU placed into?
Components of the CPU The Arithmetic and Logic Unit (ALU) is where the CPU performs the arithmetic and logic operations. Data is passed to the ALU to allow the required calculations to be carried out. The results of any calculations are then sent to be stored in a register.
Which register stores the result of ALU operations?
destination register
When the next clock arrives, the destination register stores the ALU result and, since the ALU operation has completed, the ALU inputs may be set up for the next ALU operation.
What function is performed by ALU is it an independent unit if not which unit does ALU work in coordination with?
Answer: ALU is stands for arithmetic and logical unit which perform all arithmetic operation like addition subtraction division and multiplication and logical operation of the computer system. ALU is an independent unit because it performs the function independently.
What is the function of ALU in microprocessor?
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.
Which register will temporarily store the results of calculations performed by the ALU?
RAM (Random Access Memory) When a program is running, the data that will be processed by the processor is temporarily stored in RAM. RAM will hold data until it is needed by the processor.
Which register stores the results of arithmetic and logical operations?
Accumulator
Option 2 is the correct answer: Accumulator (ACC) stores the results of arithmetic and logical operations. It contains the instructions being decoded or executed.
What is an example of an ALU?
How an ALU Works. An ALU performs basic arithmetic and logic operations. Examples of arithmetic operations are addition, subtraction, multiplication, and division. Examples of logic operations are comparisons of values such as NOT, AND, and OR.
How does the ALU affect the CPU’s performance?
When the operations become more and more complex, then the ALU will also become more and more expensive and also takes up more space in the CPU and dissipates more heat.
What are the basic operations performed by an ALU?
An ALU performs basic arithmetic and logic operations. Examples of arithmetic operations are addition, subtraction, multiplication, and division. Examples of logic operations are comparisons of values such as NOT, AND, and OR.
What is an arithmetic logic unit (ALU)?
An arithmetic logic unit (ALU) represents the fundamental building block of the central processing unit of a computer. An ALU is a digital circuit used to perform arithmetic and logic operations. What Is an ALU?
