Fetch cycle in microprocessor pdf
The microprocessor (also known as Central Processing Unit (CPU)) can be defined simply as a calculation machine. It executes predefined operations called instructions. The steps the CPU performs in order to execute an instruction is called an instruction cycle (also known as fetch-execute cycle or fetch-decode-execute cycle). Instruction Cycle - The Steps required by CPU to fetch and execute an Instruction is called a Instruction Cycle. It consist of fetch and Execute Cycle. It consist of fetch and Execute Cycle. Machine Cycle - It is a time Required by microprocessor to complete the operation of accessing memory or I/O devices is called machine cycle. Fetch, Decode, and Execute One chip is central to a personal computer. It is called a microprocessor. Sometimes a microprocessor is called "a computer on a chip." Many microprocessors are smaller than a dime, yet they play an essential role in making the computer work. A microprocessor .
