What is the main function of the ALU?
The function of the Arithmetic Logic Unit is to perform the arithmetic operations and boolean logic operations needed during instruction execution.Some Arithmetic Logic Units also provide temporary storage for operands and/or results of these operations in registers or accumulators, others do not provide any temporary storage (depending on the computer's architecture and/or implementation).
What is the function of the Logic unit?
The arithmetic-logic unit (ALU) performs allarithmetic operations (addition, subtraction,multiplication, and division) and logic operations.Logic operations test various conditions encounteredduring processing and allow for different actions to betaken based on the results. The data required to performthe arithmetic and logical functions are inputs from thedesignated CPU registers and operands
What is 'microperation' in computer terminology?
they are very basic operations performed on registers in the form of add,sub ,shift,increment,logic operations like OR,NOR,AND etc(processing at the level of bits) ------bhavya joshi INDIA
What are the functions of execution unit in 8086 Intel?
Basically the function of execution unit in 8086 is to perform all arithmetic and logic operations.It tells the Bus Interface unit(BIU) where to fetch instructions and data from.It has 4 components:Control circuitry,ALU,Flag registers and general purpose registers. 1.control circuits-it directs all the internal operations. 2.ALU-performs all logic operations. 3.general purpose registers-used to store data during execution. 4.flag registers-it has a 16bit flag register containing 9 flags that are set for certain conditions during any operation.Ex.carry flag(whenever there is a carry). It also has a decoder to decode the fetched instructions.
What are the registers ALU and CU?
alu is arithematic logic unit. it is a part of computer system. it performs arithematic operations like +,-,*,/etc.alu is arithematic logic unit. it is a part of computer system. it performs arithematic operations like +,-,*,/etc.
Ability to perform certain logic operation?
The Logical operator has the ability to perform certain logic operations on its input. This is used in Boolean algebra.
What does boolean logic do?
boolean logic is a system for logical operations. These operations uses terms who can only have two states : TRUE or FALSE this logic as often used in computer and electronic sciences. You can answer closed questions with this logic (YES or NO) but you can't solve open questions.
What is a register in microcontroller?
Registers are small memory elements of size in few byte or word. Registers can be accessed quickly by the ALU (Arithmetic and Logic Unit) of micro controllers.
What are the function of the central processing unit?
There are 3 different types of registers: 1. Those involved in program sequencing, e.g. the "PC" register. 2. Those involved in address calculation of variable - "SP" and "B". 3. Those involved in arithmetic and logic operations, like "A" and "X" Then there are some special registers and "flags". The (1) is used by the instruction unit to identify and request the next instruction to load. The next instruction can be calculated based on a comparison "IF A > B JMP to End otherwise execute next." The registers that is used in arithmetic and logical operations are kept in the CPU to make this run faster. There is no memory access needed to add the content of 2 register, making this a much faster operation than adding memory. So, other computers than the Intel designed, use more registers and can benefit from this. The CPU will require 2 registers to be able to feed the two arguments to the ALU for evaluation, and obtain the result in one of the registers.
The component of the processor that performs arithmetic comparsion and logical operations?
The arithmetic logic unit is a digital circuit that is part of the CPU. Its main functions are to do arithmetic and logic operations.
What is the full meaning ALU in computer?
Arithmetic Logic Unit - the place where all operations happen in a computer.Other units are:Memory - data and instructions kept here.Control - coordinates all units according to instructions.Input/Output - moves data and instructions in and out of the computer.
Which group of instruction do not effect the flag?
(a) Arithmetic operations (b) Logic operations (c) Data transfer operations (d) Branch operations
