What is the ALU and what is it used for?
In computing, an arithmetic logic unit (ALU) is a combinational digital circuit that performs arithmetic and bitwise operations on integer binary numbers. This is in contrast to a floating-point unit (FPU), which operates on floating point numbers.
What is ALU and explain the process?
An arithmetic-logic unit is the part of a central processing unit that carries out arithmetic and logic operations on the operands in computer instruction words. In some processors, the ALU is divided into two units: an arithmetic unit (AU) and a logic unit (LU).
What functions are performed by ALU is it an independent unit?
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 ALE function?
Answer: ALE stands for address Latch Enable, as address and data bus are multiplexed, ALE is used to lock either Address or Data. Answer: ALE refers as address latch enable, the function of ALE is to control the set of latches or FF’s in microprocessor.
What is the function of ale pin in 8051?
ALE stands for Address Latch Enable. It is input, active-high pin. This pin is used to distinguish between memory chips when multiple memory chips are used. It is also used to de-multiplex the multiplexed address and data signals available at port 0.
What is the function of Alu in computer?
ALU is the “calculator” portion of the computer. An arithmetic logic unit (ALU) is a major component of the central processing unit of the a computer system. It does all processes related to arithmetic and logic operations that need to be done on instruction words.
What is the ALU in microcontroller?
Microcontroller Microprocessor Computers Inside a computer, there is an Arithmetic Logic Unit (ALU), which is capable of performing logical operations (e.g. AND, OR, Ex-OR, Invert etc.) in addition to the arithmetic operations (e.g. Addition, Subtraction etc.).
What does ALU stand for?
Arithmetic Logic Unit (ALU) Inside a computer, there is an Arithmetic Logic Unit (ALU), which is capable of performing logical operations (e.g. AND, OR, Ex-OR, Invert etc.) in addition to the arithmetic operations (e.g. Addition, Subtraction etc.). The control unit supplies the data required by the ALU from memory, or from input devices,
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?
