Summer training embedded system and its scope
- 1. Embedded System and Its SCOPE by CETPA INFOTECH PVT. LTD.
- 2. What is a system? A system is a way of working, organizing or doing one or many tasks according to a fixed plan, program or set of rules. A system is also an arrangement in which all its units assemble and work together according to the plan or program.
- 3. SYSTEM EXAMPLES WATCH • It is a time display SYSTEM • Parts: Hardware, Needles, Battery, Dial, Chassis and Strap • Rules 1. All needles move clockwise only 2. A thin needle rotates every second 3. A long needle rotates every minute 4. A short needle rotates every hour 5. All needles return to the original position after 12 hours
- 4. EMBEDDED SYSTEM An embedded system consists of hardware and software. When chips are built into systems and software is loaded on that for a particular functionality, it becomes an embedded system. SOFTWARE PROGRAM #include <16f876a.h> #use delay (clock=20000000) #byte PORTB=6 main() { set_tris_b(0); portb=255; //decimal delay_ms(1000); portb=0x55; //hexadecim al delay_ms(1000); portb=0b10101010; //binary delay_ms(500); }
- 5. COMPONENTS OF EMBEDDED SYSTEM • It has Hardware Processor, Timers, Interrupt controller, I/O Devices, Memories, Ports, etc. • It has main Application Software Which may perform concurrently the series of tasks or multiple tasks. • It has Real Time Operating System (RTOS) RTOS defines the way the system work. Which supervise the application software. It sets the rules during the execution of the application program. A small scale embedded system may not need an RTOS.
- 7. EMBEDDED SYSTEM CONSTRAINTS An embedded system is software designed to keep in view three constraints: – Available system memory – Available processor speed – The need to limit the power dissipation When running the system continuously in cycles of wait for events, run, stop and wakeup.

- 34. Industrial Use of Embedded System
- 35. 3.5 million jobs by 2015, but talent missing • According to an ISA-Ernst & Young report of 2011, this industry was about $6.5 billion in 2009 and is expected to log a compound annual growth rate of 17.3 per cent to reach $10.6 billion in 2012. • The report also suggests that the industry promises 3.5 million jobs by 2015. But unfortunately, the industry is grappling with the problem of talent shortage. • Embedded software segment now offers more high-value activities relating to middleware, driver design and associated applications. The main reason for increased adoption of embedded software is its use by electronics companies for increased device functionality, reduced time-to-market and reduction in costs.
- 36. Raw talent: key challenge for companies • Several engineering universities in the country are far from understanding the requirements of the industry and train the students accordingly. • This has resulted into two extremes, where on one hand the industry needs talent and on the other hand there is an abundance of engineers who have not been trained in necessary skills. • Industry veterans term these engineers as ‗raw talent‘ and training to make them productive is a key challenge for them.
- 37. • Companies face a tough time trying to recruit the right set of people. There are certain portions in the entire embedded ecosystem where generic electronics knowledge will help. Hardware design is one example. But then there are certain other segments, which require a good experience in device driver, software amplification, etc. The industry is missing this talent big time.
- 38. Roles available • Embedded engineers write the software that controls the VLSI chips. Embedded software can be any code which interacts with the hardware layer, ranging from the hardware abstraction layer, device drivers, kernel programming to application programming. • To take up embedded software development as career, you need to have a working knowledge of C, C++ and Java, with some exposure to application software development. If you have already done some programming for an embedded system, you can expand your horizons by broadening your skill sets
- 39. • Embedded software is being developed using a variety of embedded and real-time operating systems, such as embedded NT, Windows CE and RTLinux. In addition, a variety of development tools and IDEs for C, C++ and Java are available. You need to learn application development in these various environments. • To be a successful programmer, you need a good understanding of design alternatives—how to choose a processor, an operating system, a programming language so that you can develop cost-effective, reliable embedded software with minimal development time. As many of the systems become network enabled, a working knowledge of network programming is also important. Also, you need to be aware of the diversity of application areas and the specific requirements of each.
- 40. • As a hardware/board designer, you could work on reference board design, new board design, and board design derivatives and modifications on existing boards. Reference boards are used to validate the capabilities of designed silicon chips. • The embedded hardware designer is responsible for hardware design schematic , PCB layout, BOM creation, hardware board debugging and testing, and system integration testing. Desired skills are hardware design using 8-/16-/32-bit microcontrollers, microprocessor-based systems, design of medium-frequency boards, hardware design of analogue , mixed signal and digital, and understanding/ implementation of the EMI and EMC concepts to hardware design.
- 41. Desired qualifications and skill set • The minimum requirement is a bachelor‘s/ master‘s degree in engineering with specialisation in electronics and electrical or computer science. But it is preferable for a candidate to have some hardware integration experience, good software coding skills and the ability to deal with and develop algorithms to solve problems. • Today, universities are offering special streams like software design and engineering, microelectronics and automotive embedded system. It is a great idea to undergo such a course as it will provide the requisite industry knowledge in the field you want to pursue a career.
- 42. VERY IMPORTANT One important thing to remember though, is that you should not think about yourself as only a software guy or a hardware guy. Rather, see yourself as more of a systems person. You should be versatile enough to be able to take risks and challenges when troubleshooting a problem at the board moving between hardware and software areas.
- 43. Career growth over time • As you gain experience and knowledge, you will be required to work more independently making decisions, developing designs and solving problems. With further experience, you may become a technical specialist or supervisor in a team of engineers or technicians. Eventually, you may become an engineering manager or move into other managerial or completely technical domain. • As a fresher you might typecast yourself into a certain role. Later on, this boundary has to blur totally. You have to start understanding both hardware and software, device drivers, register mapping and application software development.
- 44. • Also, as embedded system is part of many applications, you have to figure out the domain knowledge. For example, if you are working on embedded systems for telecom applications, you should be able to find out the user experience and with better creativity decide which layout or colour will look better. You start becoming a system architect finally. • Automotive, telecom and security are the industries where a lot of embedded work is going on. Industrial and medical applications, which were lagging behind, are also making significant improvements. As a professional, you can switch from one vertical to another as you gain knowledge of how an embedded system works. One added advantage here will be knowing the particular vertical requirements and applying the related skill set.
- 45. Compensation • Salaries are based on individual skill set and qualifications. An engineer starting his career with a bachelor‘s degree can expect anything between Rs. 400,000 and Rs. 700,000 per annum. Many companies give higher salaries to engineers with M.Tech or Ph.D based on continual performance, knowledge and competence. Unlike many other industries, the embedded industry has seen quite a steep salary growth across levels and it still continues.
- 46. Some good institutions to study CETPA INFOTECH (Two times awarded as the Best IT and Embedded Training Company),IITs, NITs, BITs, Punjab Engineering College, IT BHU, Thapar and Delhi Technical University are some of the names to reckon with for studying embedded systems.

- 52. Looking ahead • Much of the growth in embedded computer systems will be propelled by more sophisticated, cloud connected embedded systems, which will have faster chips, better connectivity and more advanced operating systems and analytical software. • An ever-increasing number of appliances will be monitored or controlled remotely. Further developments in microelectronics will lead to an era of invisible computing, wherein the computer does the job we need but without an ubiquitous presence. • As electronics becomes more and more pervasive in our lives with the mobile phones, intelligent home appliances and vehicles, and more recently the insulin pumps that reside inside the body, a career in embedded systems seems only to be getting better with time, for these are no longer talking of ‗cutting edge‘ but technology at the ‗bleeding edge!‘
