- 4. INTRODUCTION • A collection of components that work together to realize some objec- tives forms a system. Basically there are three major components in every system, namely input, processing and output. • An embedded system is a combination of computer hardware and software designed for a specific function. Embedded systems may also function within a larger system. • While embedded systems are computing systems, they can range from having no user interface (UI). • For example, on devices designed to perform a single task to complex graphical user interfaces (GUIs), such as in mobile devices.
- 5. EMBEDDED SYSTEMS • An embedded system is a microprocessor-based computer hardware system with software that is designed to perform a dedicated function, either as an independent system or as a part of a large system. • Embedded systems are commonly found in consumer, industrial, automotive, home appliances, medical, telecommunication, commercial, aerospace and military applications. • Learning about embedded systems will introduce you to various hardware components that are used in non-computer devices.
- 6. STRUCTURE IN EMBEDDED SYSTEMS
- 7. ABOUT MICROCHIP TECHNOLOGY • Microchip Technology makes one of the most widely used 8-bit controllers. Called PIC processors, they are extremely simple and cheap. • There are hundreds of versions with different memory sizes and configurations and various mixes of interfaces. One of the simpler versions is the 16C54. It has a single working register, W, that is the accumulator. It uses a bank of 24–73 registers for RAM. • ROM for program storage ranges from 512 bytes to 2 KB. I/O occurs via 4- or 8-bit parallel ports. Larger versions have more RAM and more ROM, higher clock speeds, a built-in ADC, and special network interfaces like CAN. Several 16-bit versions are also available.
- 8. DIFFERENCES EMBEDDED SYSTEMS • These are designed to do some specific set of tasks. • It uses semiconductor memories,but does not require secondary memories like hard disk,CD.lt sometime has special memory called flash memory. • It is designed using a microcontroller as the main processing unit. GENERAL PURPOSE SYSTEMS • It can perform multiple tasks. • It contains a large memory semiconductor memories like cache and RAM. It also contains secondary storage like hard disks etc. • It is designed using microprocessor as the main processing unit.
- 9. CHARACTERISTICS OF EMBEDDED SYSTEMS • Unlike general computer systems, embedded systems work only for a particular function in a time-bound manner. For instance, a washing machine can not multitask like a laptop. In this regard, here are some unique characteristics of an embedded system. Sophisticated Functionality • The functionality of no two embedded system applications is bound to be the same. The functionality of a washing machine is different from that of a microwave. However, the functionality of a laptop and a desktop are almost the same. Real-Time Operation • It doesn’t mean live operation. It means the software programs hardware to operate in a time-bound fashion. It could also have two modes: Hard and Soft. The former mode indicates the task has to be completed within the allotted time (ex: clock), but in the soft mode, the system could use additional time over the allotted time (ex: microwave).
- 10. APPLICATIONS Embedded sytems control many of common devices in use today,like • Digital watches • Traffic lights • Printers • Mobile phones • Mp3 players • Robotics • Climate control in automation etc…,.
- 11. FUTURE EMBEDDED SYSTEMS • The future of embedded systems includes robust security measures, such as hardware-based security modules and advanced encryption techniques, to protect data and privacy. the future of embeddedsystems and how they are shaping the world around us: 1. The Rise of Intelligent Embedded Systems 2. The Internet of Things (IoT) Integration 3. Security • The future of embedded systems is bright with several key predictionsshaping the industry. One of the primary predictions is an increased demand for low-power, high-performance embeddedsystems. As devices become more connected and intelligent, they will require more processing power while consuming less energy.
- 12. CONCLUSION • Embedded systems is unique and hardware is highly specialized to application domain. As a result,embedded sytems programming can be widely varying experience. • It seems inevitable that the number of embedded systems will continue to increase rapidly. THANK YOU
