What is the mechanism inside a computer that actually does the arithmetic and logical operations
What are arithmetic and logical operations in computers?
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. … Operations can be accomplished by connecting multiple transistors.
Which part of the computer does arithmetic operations?
ALU
An arithmetic unit, or ALU, enables computers to perform mathematical operations on binary numbers. They can be found at the heart of every digital computer and are one of the most important parts of a CPU (Central Processing Unit).
What in computers are capable of performing arithmetic and logical operations?
An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs.
What is the arithmetic logic unit of a computer?
The arithmetic-logic unit (ALU) is that functional part of the digital computer that carries out arithmetic and logic operations on machine words that represent operands. It is usually a part of the central processing unit (CPU–q.v.).
What is the difference between arithmetic and logical operations?
Arithmetic operators perform their actions on numbers. … Logical operators compare two values and, based on whether the comparison is true (or false), return either a “true” or “false.”
What is the function of arithmetic and logic unit?
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.
What is Alu explain its components briefly?
Stands for “Arithmetic Logic Unit.” An ALU is an integrated circuit within a CPU or GPU that performs arithmetic and logic operations. Arithmetic instructions include addition, subtraction, and shifting operations, while logic instructions include boolean comparisons, such as AND, OR, XOR, and NOT operations.
What is the location of the outcome of an arithmetic and logical operation?
The correct answer is In Accumulator.
How does the control unit work?
A control unit or CU is circuitry that directs operations within a computer’s processor. … A control unit works by receiving input information that it converts into control signals, which are then sent to the central processor. The computer’s processor then tells the attached hardware what operations to carry out.
How does the ALU affect the performance of a microprocessor?
Using its ALU (Arithmetic/Logic Unit), a microprocessor can perform mathematical operations like addition, subtraction, multiplication and division. … A microprocessor can move data from one memory location to another. A microprocessor can make decisions and jump to a new set of instructions based on those decisions.
What are the basic arithmetic and logic operations for a 1 bit ALU?
So with the above building blocks, lets construct a simple ALU that performs a arithmetic operation (1 bit addition)and does 3 logical operations namely AND, NOR and XOR as shown below. The multiplexer selects only one operation at a time.
…
The basic Unit: 1 bit ALU.
| Inputs | Outputs | |
|---|---|---|
| M1 | M0 | Operation |
| 1 | 0 | AND |
| 0 | 1 | OR |
| 1 | 1 | XOR |
What are the control unit and arithmetic logic unit components of a processor?
The central processing unit (CPU) consists of six main components: control unit (CU)arithmetic logic unit (ALU)registers.
…
Control unit
- it fetches , decodes and executes instructions.
- it issues control signals that control hardware.
- it moves data around the system.
What functions are performed by the control unit can we call it the control Centre of computer system Why?
Answer: The Control Unit (CU) controls and guides the interpretation, flow and manipulation of all data and information. The CU sends control signals until the required operations are done properly by ALU and memory.
How does a 1 bit adder work?

How many arithmetic and logic operations are possible in a 4 bit ALU?
16 logical operations
The 4-bit wide ALU can perform all the traditional add / subtract / decrement operations with or without carry, as well as AND / NAND, OR / NOR, XOR, and shift. Many variations of these basic functions are available, for a total of 16 arithmetic and 16 logical operations on two four-bit words.
What is NAND logic gate?
In digital electronics, a NAND gate (NOT-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus its output is complement to that of an AND gate. A LOW (0) output results only if all the inputs to the gate are HIGH (1); if any input is LOW (0), a HIGH (1) output results.
What is Binary Adder explain?
Binary Adders are arithmetic circuits in the form of half-adders and full-addersb used to add. together two binary digits. Another common and very useful combinational logic circuit which can be constructed using just a few basic logic gates allowing it to add together two or more binary numbers is the Binary Adder.
How does a ripple carry adder work?
Ripple Carry Adder works in different stages. Each full adder takes the carry-in as input and produces carry-out and sum bit as output. The carry-out produced by a full adder serves as carry-in for its adjacent most significant full adder. When carry-in becomes available to the full adder, it activates the full adder.
What is bubbled AND gate?
Bubbled AND gate: The AND gate with inverted inputs is called as Bubbled AND gate which is also called as negative AND gate. NOR gate is also called as an active low AND gate since its output becomes high only when all its inputs are equal to 0.
What is latch circuit?
