How does a CPU Execute Instructions: Understanding Instruction Cycles
On October 15, 2022 In Computer Architecture
In this post, we will understand how a CPU executes instructions on a high level by illustrating the instruction cycle using a step-by-step example. We also cover interrupts and how they affect the instruction cycle. A CPU executes instructions using a cycle of steps known as the instruction cycle. What is an Instruction Cycle?
What is the Von Neumann Architecture
On October 4, 2022 In Computer Architecture
The von Neumann architecture is a foundational computer hardware architecture that most modern computer systems are built upon. It consists of the control unit, the arithmetic, and logic unit, the memory unit, registers, and input and output devices. The key features of the von Neumann architecture are: Data as well as the program operating
