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
How many types of accumulated register?
Accumulated registers typically come in two main types: accumulator registers and data registers. Accumulator registers are used to store intermediate results of arithmetic and logic operations, while data registers hold data temporarily during processing. Additionally, some systems may feature specialized accumulated registers for specific functions, but the primary distinction remains between accumulators and data registers.
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 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
Memory cells built right into the CPU that contain specific data needed particularly the Arithmetic and Logic Unit.?
Memory cells built into the CPU that specifically support the Arithmetic and Logic Unit (ALU) are known as registers. Registers provide high-speed storage for data and instructions that the ALU uses during computations, allowing for faster processing compared to accessing data from main memory. They play a critical role in executing arithmetic operations and logical comparisons efficiently. Each register typically has a specific purpose, such as holding operands or storing intermediate results.
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 the function of execution unit?
The execution unit (EU) is a component of a computer's central processing unit (CPU) responsible for carrying out instructions from the program being executed. It performs various operations, such as arithmetic, logic, and control operations, by processing data and executing the commands specified by the instruction set architecture. Essentially, the execution unit takes the processed data and executes the necessary computations to produce results, which are then sent to the appropriate registers or memory locations.
What are the registers ALU and CU?

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.
