It is clear that mobile phone is a complex device housing a number of functions. The variation of these functionalities can only be achieved by a very flexible device. This flexible device is known as EMBEDDED PROCESSOR and the MOBILE PHONE housing the functions is known as EMBEDDED SYSTEM. www.ppttopics.com
What is an EMBEDDED SYSTEM? A combination of hardware and software which together form a component of a larger machine. An embedded system performs pre-defined tasks, usually with very specific requirements. Since the system is dedicated to a specific task, design engineers can optimize it, reducing the size and cost of the product. www.ppttopics.com
Hence, both the software and the hardware components are co-designed. A Software programmer writes code that utilize hardware and Hardware engineer design hardware to assist programmer . Hence, both the software and the hardware components are co-designed. SOFTWARE PROGRAM www.ppttopics.com
Not all embedded systems work on this concept. REAL TIME SYSTEMS An operation within a larger dynamic system is called a real-time operation if the combined reaction- and operation-time of a task is no longer than the maximum delay allowed. Embedded systems working on this concept are called REAL TIME EMBEDDED SYSTEMS. Not all embedded systems work on this concept. www.ppttopics.com

PROCESSORS IN EMBEDDED SYSTEMS Processor is the heart of an embedded system. CLASSIFICATION MICROPROCESSOR (μP) They use separate integrated circuits for memory and peripherals of the system. MICROCONTROLLER (μC) They have many more peripherals on chip, reducing power consumption, size and cost. www.ppttopics.com
Numerous microcontrollers have been developed for embedded systems use Numerous microcontrollers have been developed for embedded systems use. General-purpose microprocessors are also used in embedded systems, but generally require more support circuitry than microcontrollers. The first microprocessor INTEL 4004, was designed for calculators and other small systems but still required many external memory and support chips. By the mid-1980s, most of the common previously external system components had been integrated into the same chip as the processor which formed the microcontroller and it allowed even more widespread use of embedded systems in various fields. www.ppttopics.com
The embedded systems application took a wide increase in the many fields and also added to the economical growth of the nations www.ppttopics.com
