Class: SHS 1 / Grade 10 Period: [Period number, e.g., 1 & 2] Lesson Topic: Memory Architectures in Embedded Systems (RAM & ROM)
(35 minutes)
This is the main content delivery phase. Use analogies and draw diagrams on the board to illustrate concepts. A. What is an Embedded System? (Recap)
An embedded system is a combination of computer hardware and software designed for a specific function. It is "embedded" as part of a complete device. Examples: Traffic lights, digital watches, washing machines, mobile money POS terminals, digital TV decoders. Core Components: It always has a microcontroller or microprocessor (the "brain") and memory (the "memory"). B. The Role of Memory: Why is it Needed?
The "brain" (microcontroller) needs a place to store two things: Instructions: The program or set of steps it must follow. (e.g., for a traffic light: "1. Turn Red light on for 60 seconds. 2. Turn Yellow light on for 5 seconds. 3. Turn Green light on for 60 seconds. 4. Repeat."). Working Data: Temporary information it is working with right now. (e.g., for a traffic light with a sensor: "How many cars are currently waiting? The count is 12.").
