Embedded System(ES): Any device that includes a computer but is not itself a general purpose computer
-> Hardware & Software part of some larger system are expected to function without human intervention.
->Respond , monitor , control external environment using sensors and actuators .
Eg: PDA,printer,Cell phones etc
Characteristic of an ES:
1) Sophisticated features (functionality)
2)Real time Operation (Not always)
3)Low Manufacturing Cost
4)Application dependent processor (Not General purpose)
5)Restricted memory
6)Low power
Power consumption is critical in battery powered devices. Excessive power consumption increases system cost even in wall powered devices.
Manufacturing Cost:
1)Manufacturing...
