Sub Strand: 1.5 Central Processing Unit (CPU)

STRAND 1.0: FOUNDATION OF COMPUTER STUDIES

Sub Strand: 1.5 Central Processing Unit (CPU)

Specific Learning Outcomes

By the end of the sub strand, the learner should be able to:

a) describe the structural elements of the CPU of a computer system,

b) relate structural elements of the CPU to their functions,

c) examine the types of CPUs in computing devices,

d) appreciate the role of the CPU in a computer.

Suggested Learning Experiences

The learner is guided to:

• brainstorm the structural elements of the CPU,
• watch a video simulation of the structural elements of the CPU,
• discuss the functions of the structural elements of the CPU (arithmetic and logic unit, control unit, registers, buses),
• draw a diagram to show the fetch-decode-execute cycle and the interaction between CPU, registers and memory,
• compare types of CPU in computing devices according to instruction set (RISC vs CISC); word length (16-bit, 32-bit, 64-bit); core design (single-core, dual-core, quad-core, hexa-core, octa-core, deca-core),
• discuss factors to be considered when selecting a CPU,
• develop print or digital content and use it to educate peers on the role of a CPU in a computer.

Suggested Key Inquiry Question(s)

1. What are the technological advancements in the development of CPUs?
2. How does the CPU relate to the human brain?

Core Competencies to be Developed

Critical Thinking and Problem Solving: The learner demonstrates the fetch-decode-execute cycle interaction with the CPU.

Creativity and Imagination: The learner gains new knowledge as they discuss the functions of the structural elements of the CPU.

Values

Unity: The learner appreciates the efforts of others as they draw diagrams to show the fetch-decode-execute cycle and the interaction between CPU, registers and memory.

Respect: The learner understands and appreciates others’ opinions as they brainstorm the structural elements of the CPU.

Pertinent and Contemporary Issues (PCIs)

Social Awareness Skills: The learner develops effective communication skills while discussing the factors to consider when selecting a CPU.
