What is embedded system?
There is no one answer. An embedded system is any
software system that must be designed on a
platform different from the platform on which the
system is intended to be deployed.

• But
• Embed Micro processor or Micro controller in a
  machine
• Special purpose system
• Small and limited capacity
• Suitable for massive product
• These days evolutions of hardware are reducing a
  difference between embedded systems and general
  purpose systems

Embedded System H/W

• Microprocessors
• Are a very efficient way to implement digital
  system
• Provide new feature to keep up with rapidly
  changing market
• 8bit/16bit/32bit
• Arm, Power PC, MIPS
• Memory
• storage for program and data
• RAM/ROM/FLASH memory
• Peripheral device
• I/O with User, Devices for Microprocessor
• Key button, touch screen, LCD
• Network interface chip, Sound codec, UART

6
Embedded Computing Applications

• Complex Algorithms
• User interface
• Real time
• Multirate
• Manufacture Cost
• Power

This issue is not only for embedded system but
all of computer systems

Challenges of embedded system design

• Main Issues of embedded systems are
• How much H/W do we need?
• How do we meet deadlines?
• How do we minimize power consumption?
• How do we design for upgrade-ability?
• Does it really work?
• How much we produce massively?
• Is it fast?
• But
• Complex testing
• Limited absorbability and control ability
• Restriction development environments
