Embedded Systems theory Flashcards
What is an embedded system?
combination ->software +hardware -> performs specific task rather than a general purpose computer ->designed to carry out multiple tasks
What can they deigned to be?
Small+low cost
What saves large amounts of money?
Mass production- embedded systems
What is the software written known as?
Firmware
What do they run on?
ROM or Flashdrive
Type of embedded system: Electronics
What are the uses?
Smart phone, game console, printer,
television, digital camera
Type of embedded system: Home
What are the uses?
Washing machines, microwave ovens, fridge, dishwasher, air conditioning unit
Type of embedded system: Medical
What are the uses?
CT Scans, electrocardiogram, MRI scanners, blood pressure monitors, heartbeat monitors
Type of embedded system: Car
What are the uses?
Electronic fuel injection system, anti-lock braking system, air-conditioning units
What are most known as?
What conditions do they react to and how do they react?
Reactive
Temperature, weight, vibration and air quality. They detect external conditions and react by recording data, turning motors on/off, sounding an alarm or sending a message
What do embedded systems often control?
Real-time events, so must be completely reliable, for example an anti-lock braking system on a car
When most reliable?
When - perform -> high speed.
What is the size of embedded system and power consumption if it can be easily changed for diff situation?
size of the embedded system = small
power consumption = low,
- easily adapted for different situations
