Computer Architecture
Gbogbo ọrọ náà
Inside every computer is a single chip that does the actual thinking: the central processing unit. It does not work by magic but by repeating one tireless three-step routine billions of times a second, fetching an instruction, decoding it, then carrying it out. Understanding that cycle, and the small set of registers and units that perform it, is the key to explaining how any program runs.
In this lesson you will learn the role of the CPU and the microprocessor, walk through the fetch-decode-execute cycle component by component on a Von Neumann machine, and see how cores, cache and clock speed change performance. You will also meet the instruction set and the embedded systems that quietly run the devices around you.
Ebumnobi
- 1 (a) Understand the role of the central processing unit (CPU) in a computer (b) Understand what is meant by a microprocessor
- 2 (a) Understand the purpose of the components in a CPU, in a computer that has a Von Neumann architecture (b) Describe the process of the fetch-decode-execute (FDE) cycle, including the role of each component in the process
- 3 Understand what is meant by a core, cache and clock in a CPU and explain how they can affect the performance of a CPU
- 4 Understand the purpose and use of an instruction set for a CPU
- 5 Describe the purpose and characteristics of an embedded system and identify devices in which they are commonly used
