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

Explain about alu with block diagram?

An ALU (Arithmetic Logic Unit) is a digital circuit that performs arithmetic and logical operations on binary numbers. Its block diagram consists of input registers, a control unit, arithmetic logic circuits, and output registers. Input operands are fetched from the registers, processed by the ALU based on the control signals, and the result is stored back in the output registers. It is a critical component of a CPU responsible for executing arithmetic calculations and logical operations.


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 Advantage of using general purpose registers in 8086?

The advantages of using general-purpose registers in the 8086 microprocessor include increased flexibility for data manipulation, as they can be used for various operations such as arithmetic, logic, and data transfer. They help simplify instruction encoding by allowing the use of a uniform set of operations across different registers. Additionally, general-purpose registers facilitate efficient programming by enabling quick access to frequently used data, thereby improving overall execution speed. Lastly, the use of these registers can reduce memory access, which enhances performance by minimizing delays associated with fetching data from RAM.


What categories of data are commonly supported by user-visible register?

User-visible registers commonly support several categories of data, including general-purpose data for arithmetic and logic operations, control and status information, and memory addresses for data manipulation. They may also include special-purpose registers for specific functions like instruction pointers or stack pointers. Additionally, some architectures provide registers for floating-point operations and SIMD (Single Instruction, Multiple Data) processing. Overall, user-visible registers facilitate efficient data handling and processing within the CPU.

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.


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 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.
