What else can I help you with?
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 are the phases of instruction cycle?
There are four phase of an instruction cycle namely: fetch; indirect; execute; write.
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.
How do you explain the model of destination life cycle?
explain the destination life cycle explain the destination life cycle
What is the name of the cycle in which an instruction is taken from memory and loaded into the instruction register?
Fetch
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.
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
Define t-state in machine cycle and instruction cycle?
acknowledges
Demonstrate a correct understanding of the fetch execute cycle of microprocessor?
The fetch-execute cycle of a typical microprocessor involves fetching an instruction from memory, determining what actions the instruction requires it to do, and performing those actions. It is also simply called the Instruction Cycle.
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 fetches and decodes instructions in a computer?
An instruction cycle.
