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 the difference between instruction cycle and machine cycle?
an instruction cycle may consist of a number of machine cycles.
What is two main phases of the cell cycle?
The two main phases of a cell cycle are interphase and mitosis.
What are the different phases of instruction cycle?
Play drive: The impulse or need within a child or young person that starts the play cycle. Play cue when a child signals that they want to play, facial expressions, body language or when a child shows that they want to play with another. Play return: The response to a play cue, which can come from another person, the environment or from the child playing. Play frame: The process or space that is created by cues and returns. It's a boundary that keeps the play intact. It begins with the child's play drive and includes all that allows play to continue. It may be as big as a football pitch or as small as a chessboard and the two people playing. As a playworker you can be inside or outside of the frame depending on the level of the playworkers involvement.
What are the different phases in instruction execution explain?
Instruction execution can be divided into five phases. These are Phase-I: INSTRUCTION FETCH (IF) II: INSTRUCTION DECODE & OPERAND FETCH (ID) III: EXECUTION (EX) V: MEMORY OPERATION (MEM) V: WRITE BACK (WB) - Regards, Subhradip Das
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.
How does the CPU keep track of which instruction to execute next?
The instruction register holds a pointer to the current instruction (in working memory) while the next instruction register points to the next instruction (the first instruction immediately after the current instruction's operands). If the current instruction is a jump instruction, it can change the next instruction register, allowing the program to branch to a new instruction once the jump instruction is processed. The next instruction pointer is automatically moved into the current instruction register once the current instruction has been processed. The entire process of executing an instruction is known as the fetch-decode-execute cycle.
The instruction cycle is also known as the .?
The instruction cycle is also known as the fetch-decode-execute cycle. It refers to the process by which a computer retrieves an instruction from memory, interprets it, and then executes it. This cycle is fundamental to the operation of a CPU, enabling it to perform tasks and run programs efficiently.
How would you describe the fetch execute cycle?
Fetch Execute Cycle A more complete form of the Instruction Fetch Execute Cycle can be broken down into the following steps: 1. Fetch Cycle 2. Decode Cycle 3. Execute Cycle 4. Interrupt Cycle 1. Fetch Cycle The fetch cycle begins with retrieving the address stored in the Program Counter (PC). The address stored in the PC is some valid address in the memory holding the instruction to be executed. (In case this address does not exist we would end up causing an interrupt or exception).The Central Processing Unit completes this step by fetching the instruction stored at this address from the memory and transferring this instruction to a special register - Instruction Register (IR) to hold the instruction to be executed. The program counter is incremented to point to the next address from which the new instruction is to be fetched. 2. Decode Cycle The decode cycle is used for interpreting the instruction that was fetched in the Fetch Cycle. The operands are retrieved from the addresses if the need be. 3. Execute Cycle This cycle as the name suggests, simply executes the instruction that was fetched and decoded
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.
