Instruction Cycle Explained: Fetch, Decode, & Execute | Computer Organization (COA)

In this video, we explain the Instruction Cycle — the fundamental sequence of steps a CPU performs to execute each instruction in a program. You’ll learn about how the CPU fetches, decodes, and executes instructions and how the registers and control signals work during each stage. 📌 Topics Covered: ✔ What is the Instruction Cycle ✔ Fetch, Decode, and Execute Stages ✔ CPU Registers (PC, IR, MAR, MDR) ✔ Flow of Instruction Cycle ✔ Examples for better understanding [00:00] - Introduction: Definition of the Instruction Cycle and its importance in Computer Organization. [02:30] - Basic Phases: Overview of the Fetch, Decode, and Execute stages. [05:15] - Fetch Phase: How the CPU retrieves instructions from memory using registers like the Program Counter (PC) and Memory Address Register (MAR). [09:45] - Decode Phase: How the Control Unit interprets the instruction stored in the Instruction Register (IR). [13:20] - Execute Phase: The actual processing of the data, often involving the ALU (Arithmetic Logic Unit). [18:10] - Register Summary: A review of the specific roles of PC, MAR, MDR, and IR throughout the cycle. [21:00] - Conclusion: Summary of the complete cycle and its repetition.
