Sensors and actuators : 

Sensors and actuators A sensor is a device that responds to a physical stimulus (as heat, light, sound, pressure, magnetism, or a particular motion) and transmits a resulting impulse (as for measurement or operating a control). An actuator is a mechanical device for moving or controlling something

Embedded programming languages……Many : 

Embedded programming languages……Many C has become the language of embedded programmers Advantages of C Small Easy to learn Wide compiler support Large body of experience Processor independent Low level programming language

Embedded programming languages : 

Embedded programming languages C gives embedded programmers large degree of direct hardware control without sacrificing the benefits of a HLL Produces relatively compact efficient code for a wide variety of processors C++ and Ada are also good No more assembly required (mostly)

Trends in embedded systems : 

Trends in embedded systems Increasing code size average code size for embedded systems has been increasing dramatically 1992; avg code size - range of 16-64K bytes 1996; the average size had grown to 64K-512K This trend is continuing Migration to higher level language from sssembly As applications become more and more complex, programmers are transitioning to higher level languages for productivity reasons

Trends in embedded systems : 

Trends in embedded systems Increasing reuse of pre-designed components these include DSP chips as well as other microprocessors and microcontrollers Migration to a core-based design Systems becoming more complex and heterogeneous There are more ASIC-based designs with high speed as well as high integration Larger microprocessors are used with 32-bit processors becoming the norm

Some Thoughts-Essential in troubled Times : 

Some Thoughts-Essential in troubled Times Why do a country which can send satellites to moon still need to purchase a tape recorder /USB Drive/Cell phone made in China/Japan/US…? Whats lacking in us…?,why are we paying 16000crores for importing Embedded systems????
