Embedded Systems

• Hardware is driven and controlled by software

• Software runs in a computer system (usually a micro-controller)

• Preprogrammed to do specific functionLET US LOOK INTO SOME EXAMPLES……


Embedded System ???......

• Microcontroller based lock

• Thermostat controller

guidance systems• Industrial applications• Robotics


Applications


System organization

• Computer design requirement

• System-level requirement


Embedded system design requirement

• Real time/reactive operation• Small size, low weight• Safe and reliable• Harsh environment• Cost sensitivity


Computer design requirement

• End product utility• System safety and reliability• Controlling physical systems• Power management


System-level requirement

• Round robin scheme LOOP:AWAIT TICK;READ S1;TAKE ACTION(S1);READ S2;TAKE ACTION(S2);READ S3;TAKE ACTION(S3);FOREVER


Software design issues


Concurrent Programming

FEATURES:

• Micro kernel architecture

• Message based interprocess communication


QNX-RTOS

WAITING


PROCESS

RUNNING READY

BLOCKED

EVENT

3 LEVEL ARCHITECTURE:

• Interactive I/O interface• Reactive kernel• Data management


Synchronous Programming

• More and more produced processors are used in embedded devices

• New applications like pervasive computing are emerging


Future Possibilities
