What is the function of ALU in a microprocesser system?

Answer 1

There is a few functions that the AlU in the CPU have. The top functions thay have are memory address, I/O address and program counter.

Answer 2

ALU

Abbreviation of arithmetic logic unit, the part of a computer that performs all arithmetic computations, such as addition and multiplication, and all comparison operations. "Logical" operations - such as AND, OR and XOR is the fundamental ones, that all the others are derived from. However, the ALU functions on a computer "Word" being one or many bytes. It is given an instruction that can involve 0, 1 or 2 arguments. So the ALU is associated with the capability to access the memory - RAM and will wait until it "Memory Access Registers" are ready, will then execute the instruction. Another "ALU" will calculate the next instruction and request this. A third circuit will update the memory with any result from this operation.

The ALU is the main component of the CPU (central processing unit).

-----------In a way, the ALU is where you have at least one argument: the last answer, and can make an operation to this: A + B -> C.

The operation "+" can be arithmetic, like addition or it is logical like AND or to compare two numbers.

The ALU is made up by "gates" that takes one bit at a time.

Answer 3

To perform arithmetic or logic on bytes of data

Answer 4

Performs arithmetic and logic operations

example: addition, multiplication

Answer 5

The ALU (arithmetic and logic unit) handles all the mathematical operations of the computer, whereas the CU (control unit) manages the systems resources.

Answer 6

There is a few functions that the AlU in the CPU have. The top functions thay have are memory address, I/O address and program counter.

Answer 7

The ALU consists of a series of electronic circuits which processes arithmetic (+, -, =) and logical (and, or, not) functions. It helps the system to make decisions by computing numbers.
