The CPU fetches data and instructions from the computer's memory, primarily the Random Access Memory (RAM). When a program is executed, its instructions and the data it requires are loaded from storage (like a hard drive or SSD) into RAM, where the CPU can quickly access them. The CPU uses the memory address provided by the program counter to retrieve the relevant instructions and data.

What is the next step of CPU instruction?
The next step of CPU instruction typically involves the execution phase, where the CPU carries out the operation defined by the instruction. This follows the instruction fetch and decode stages, where the instruction is retrieved from memory and translated into a form the CPU can understand. During execution, the CPU performs arithmetic, logic, or control operations, often interacting with registers and memory to process data. After execution, the CPU will move to the next instruction in sequence, continuing the cycle.
Explain instruction fetch and execution with a state diagram?
Instruction fetch and execution are key phases in a CPU's operation cycle. In the state diagram, the process begins in the "Fetch" state, where the CPU retrieves an instruction from memory using the Program Counter (PC) to locate it. Next, the CPU transitions to the "Decode" state to interpret the instruction, followed by the "Execute" state where the instruction is carried out. After execution, the CPU may return to the "Fetch" state to retrieve the next instruction, creating a continuous loop that forms the basis of program execution.
What do you mean by 0000H?
This is the fetch instruction that the CPU takes for executing.
What is a FDE cycle within a CPU?
The FDE cycle, which stands for Fetch-Decode-Execute cycle, is the fundamental process by which a CPU operates. During the fetch phase, the CPU retrieves an instruction from memory. In the decode phase, the CPU interprets the instruction to understand what actions are required. Finally, in the execute phase, the CPU carries out the instruction, which may involve performing calculations, moving data, or interacting with I/O devices. This cycle repeats continuously to process instructions in a program.
What is the definition of fetch cycle?
Fetch cycle is defined as a part of instruction cycle in which data is fetched from the memory pointed by Holds the address of a memory block to be read from or written to) and stores the data in MDR( a two-way register that holds data fetched from memory (and ready for the CPU to process) or data waiting to be stored in memory) for further processing. Instruction cycle= Fetch cycle+ Execute cycle
What is considered a function of the instruction set for the CPU?
The Functions of the instruction set is to instruct All CPU's with a set of instructions: Tells the CPU where to find data When to read the data What to do with the data. Hope that helps Don
What is fetch execution?
Fetch execution refers to the process in computer architecture where the instruction fetch stage retrieves an instruction from memory to be executed by the CPU. This is typically the first step in the instruction cycle, where the program counter identifies the memory address of the next instruction to be fetched. Once fetched, the instruction is decoded and then executed, enabling the CPU to perform tasks as dictated by the program. Efficient fetch execution is crucial for overall system performance, as it impacts how quickly instructions can be processed.
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.
What action is taken by CPU after reset to execute first instruction of program?
The fetch-execute cycle.
What is difference between data and instruction?
Data is what is saved inside while instructions is what u instruct to do
Describe the function of the instruction set of a CPU?
They tell the CPU where to find the data, when to read it, and what to do with it.
Temporarily holds data and instruction as the CPU processes them?
Random Access
