The two-phase process for executing instructions on a typical CPU involves a fetch step and an execute step. Fetch is where the instruction is loaded from memory and execute is where the actions detailed in the instruction are carried out.

Does an interrupt actually interrupt the execution of an instruction at any time during the instruction execution cycle?

Yes , an interrupt actually interrupt the execution of an instruction at any time during the instruction execution cycle.AS there the execution takes in 4 t cycles and t3 to take up the data and the 4th cycle for execution,if there is an interruption then there will be an interruption any time in any instruction execution cycle.


What is instruction cycle with interrupts?

The instruction cycle is the basic operation cycle in a computer. This is what will take in data, process it and execute as required.


What is an instruction phase together with the execution phase called?

The instruction phase together with the execution phase is called a "Machine Cycle".


How would you explain processing cycle?

The processing cycle is the execution start date and the next execution start date of a jobnet.


What is the difference between bus cycle and instruction cycle?

Bus cycle refers to the process of transferring data between the CPU and memory or peripherals, while instruction cycle refers to the series of steps that the CPU goes through to fetch, decode, and execute instructions. In other words, bus cycle involves the movement of data, while instruction cycle involves the actual execution of instructions.


Explain instruction cycle?

An instruction cycle is the rudimentary operation cycle of any computer. It involves the CPU fetching a program from memory and executing it fully.


What refers to the amount of time it takes a CPU to execute an instruction and store the result?

The execution cycle.


How an instruction is executed in sap-1?

In SAP-1 (Simple Asynchronous Processor), instruction execution involves a series of steps. First, the instruction is fetched from memory using the Program Counter (PC), which points to the address of the next instruction. The fetched instruction is then decoded to determine the operation and the operands involved. Finally, the execution phase carries out the operation, which may involve reading from or writing to memory, updating registers, or performing arithmetic operations. This cycle is repeated for each instruction until the program completes.


What is a cycling machine?

Each time the CPU executes an instruction, it takes a series of steps. The complete series of steps is called a machine cycle. A machine cycle can be divided into two smaller cycles. These are instruction cycle and execution cycle. Instruction cycle: In instruction cycle CPU takes two steps-- 1. Fetching: Before the CPU can execute an instruction, the control unit must retrieve or fetch a command or data from the computer's memory. 2. Decoding: Before a command can be executed, the control unit must decode the command into instruction set. Execution cycle: In execution cycle CPU also takes two steps-- 1. Executing: When the command is executed, the CPU carried out the instructions in order by converting them into macrocode. 2. Storing: The CPU may be required to store the result of an instruction in memory.


How many t states are required for opcode fetch machine cycle at the execution of sequential instruction?

three


What is execute cycle in microprocessor?

The sequence of operations that the cpu has to carry out while execution is called instruction cycle. 1:- Read an Instruction 2:- Decode the instruction 3:- Find the address of operand 4:- retrieve an operand 5:- perform desired operation 6:- find the address of destination 7:- store the result into the destination


What are the 4-step machine cycle and describe what occurs at each step?

The 4-step machine cycle consists of Fetch, Decode, Execute, and Store. Fetch: The CPU retrieves an instruction from memory, using the program counter to determine the address. Decode: The fetched instruction is interpreted to understand what action is required, identifying the operation and the operands involved. Execute: The CPU performs the operation specified by the instruction, which may involve arithmetic calculations or data manipulation. Store: Finally, the result of the execution is written back to memory or a register, completing the cycle before moving on to the next instruction.
