What is the process of carrying out commands in the machine cycle?
During the machine cycle, the processor fetches instructions from memory, decodes them to understand the operation, executes the operation by performing the necessary calculations or data transfers, and then writes the results back to the appropriate location in memory. This process repeats for each instruction in a continuous loop to carry out the commands effectively.
How do microprocessers work?
Microprocessors are electronic chips that read and execute instructions to perform tasks in a computer or electronic device. They contain an arithmetic logic unit (ALU), control unit, and memory. The ALU performs mathematical operations, the control unit manages data flow, and memory stores instructions and data for processing. When powered on, the microprocessor fetches instructions, decodes them, executes the operation, and stores the result. This process repeats until all instructions are executed.
How does a prossesor work?
A processor is the "brain" of a computer, responsible for executing instructions. It fetches instructions from memory, decodes them into control signals, and executes them by performing arithmetic, logic, and other operations. The processor's performance is influenced by factors like clock speed, number of cores, cache size, and architecture.
Instruction cycle with indirect?
In an instruction cycle with indirect addressing, the CPU fetches the instruction, decodes it to determine the memory address of the operand stored in a register, fetches the operand from the memory location pointed to by the register, and executes the instruction using the operand. Finally, the CPU stores the result back in memory if needed. This extra step of fetching the operand based on the indirect memory address adds complexity to the instruction cycle.
WHAT IS Instruction fetch?
Instruction fetch is the process by which the CPU retrieves instructions from memory in order to execute them. The CPU fetches instructions one at a time, and these instructions are then decoded and executed as part of the program being run. Efficient instruction fetching is important for the overall performance of a computer system.
Does main memory provide the CPU with a working storage area for program instructions and data?
main memory provides buffers.buffers are the places where program execution takes place.but the CPU is provided with registers(memory units) there CPU can accomodate instructions and the data on which theses instructions are to be operated.from the main memory CPU fetches the instructions one by one and the instruction is processed in the CPU and then sends back the result to the main memory......i think so.thank u
I-time and e-time definition?
I-Time: In I time CU fetches an instruction from memory and place it in register. E-Time: In E time CU fetches an instruction from memory to register and place it in the Arithmetic Logic Unit.
Internal parts of a CPU and its function?
Arithmetic Logic Unit - performs arithmetic on numbers, logic functions, and manipulates symbols and strings of symbols.Control Unit - fetches and decodes instructions, controls operation of other units to execute the decoded instructions.Memory Unit - stores instructions, numbers, logical data, symbols, etc.Input/Output Unit(s) - moves instructions, numbers, logical data, symbols, etc. to and from the computer and devices outside it.
When you reboot your system the computer follows startup instructions stored in this type of memory?
On start up the computer fetches information from BIOS. BIOS is a ROM. After that the computer loads OS from Hard disk into the RAM.
Discuss in detail the design of control unit for basic system?
The control unit in a basic system is responsible for interpreting instructions and managing the flow of data within the system. It typically consists of registers, decoders, and control logic circuits. The control unit fetches instructions from memory, decodes them to determine the operation to be performed, and then generates control signals to execute the operation. It coordinates the activities of the CPU components, such as the ALU and registers, to ensure that instructions are executed in the correct sequence. The design of a control unit involves careful consideration of instruction set architecture, timing requirements, and the necessary control signals to facilitate efficient and accurate execution of instructions.
The computer that can move data and instructions between storage and memory in a process is called?
