WebJun 23, 2024 · CPU is the brain of the computer. All types of data processing operations and all the important functions of a computer are performed by the CPU. It helps input and output devices to communicate with each other and perform their respective operations. It also stores data which is input, intermediate results in between processing, and instructions. The instruction cycle (also known as the fetch–decode–execute cycle, or simply the fetch-execute cycle) is the cycle that the central processing unit (CPU) follows from boot-up until the computer has shut down in order to process instructions. It is composed of three main stages: the fetch stage, the decode … See more The program counter (PC) is a special register that holds the memory address of the next instruction to be executed. During the fetch stage, the address stored in the PC is copied into the memory address register (MAR) and … See more Each computer's CPU can have different cycles based on different instruction sets, but will be similar to the following cycle: 1. Fetch stage: The next instruction is fetched from the memory address that is currently stored in the program counter and stored into the … See more The fetch step is the same for each instruction: 1. The CPU sends the contents of the PC to the MAR and sends a read command on the control bus See more The CPU sends the decoded instruction as a set of control signals to the corresponding computer components. If the instruction involves arithmetic or logic, the ALU is utilized. This is the only stage of the instruction cycle that is useful from the perspective of … See more The cycle begins as soon as power is applied to the system, with an initial PC value that is predefined by the system's architecture (for instance, in Intel IA-32 CPUs, the predefined PC value is 0xfffffff0). Typically, this address points to a set of instructions in See more The decoding process allows the CPU to determine what instruction is to be performed so that the CPU can tell how many operands it needs to fetch in order to perform the … See more • Time slice, unit of operating system scheduling • Classic RISC pipeline • Cycles per instruction See more
