Pre-Lesson1: Part 1: Introduction to Embedded System

Embedded system consists of hardware and software design in order to perform a specific function. For example, a radio, aeroplane navigation system or even an missile.

The diagram below shown and LCD Monitor, which consists of:
 - input for various video source (Digital Input - HDMI/DVI, analog RGB, or Video).
- Scaling Engine to resize the video source to fit into the panel size
- SDRAM for video buffering or application buffering
- LVDS Tx : digital signal that contain video signal to be display on LCD panel

In current embedded system design, it is commonly to have microcontroller or microprocessor. The microcontroller can be seen as a center processing engine that control the system operation. And the control is base on a dedicated firmware that loaded into the microcontroller. This firmware allow a flexible design in embedded system whereby a same microcontroller is allow to perform different task. A same microcontroller can be use in a burglar system as well as water heater system.
