A 3D image of a mechanical heart pump inside a patient's chest has won the Wellcome Image Awards 2014. Mechanical heart pump in the thorax, DECTAnders PerssonThe Wellcome Image Awards celebrate the best in science imaging talent and techniques. The 2012 Internet Census published earlier this year revealed that embedded devices are facing serious security threats when connected to the Internet.
Embedded devices – an umbrella term defining specialized appliances that run their own operating system such as GPS receivers, industrial equipment, TV sets, smart fridges and routers – can be hijacked easily because of vendors’ lax security implementations.
According to the results of the latest Internet Census, an attacker could easily scan the IPv4 Internet space and look for hosts with UPnP or SNMP capabilities and turn them into remotely-controlled zombies. Particularly damaging about hijacking embedded devices is that subversion can last years before it gets discovered. Hi everyone, We are introducing a new author to CircuitsToday Well, here meet Anish.K, a student in engineering from Anna university. Some of the open source operating systems used in embedded systems are Android, Micro controller operating system (µCOS), VS works.
Well, we have already written a good article pointing out the basic differences between a microprocessor and microcontroller. Many companies such as Integrated electronics, Microchip, Atmel, Philips, Hitachi manufactures microcontrollers. I am impressed with the teaching language he has used & also explained along with the examples.
Embedded systems are contained in just about every electrical item in existence, and unless they break down most people are unaware of their presence.
Most embedded systems are built with 4-, 8-, and 16-bit processors, and you will have to decide which one is most suitable for the task you wish to perform. The amount of memory required to run your software will also have an effect on which processor you choose. This applies mainly to the manufacturer but also affects the consumer as a high development cost will result in a more expensive end product. Designing an embedded system can be a complicated process, but as long as you satisfy all the predicted requirements in the planning stages your finished system will function without any issues whatsoever. After completing of the training, the students are required to work on the Project work on Embedded Systems under the guidance of a Project Mentor.

The Embedded Vision Development System includes pre-verified design examples to help designers quickly implement an ASIP optimized to meet their specific SoC objectives for power consumption and performance. Processor Designer generates optimized RTL of the ASIP, which can easily be downloaded into a HAPS FPGA-based prototyping system.
Synopsys will be demonstrating the Embedded Vision Development System at the Embedded Vision Summit in San Jose, California on April 25, 2013.
The image was created by Swedish scientist Anders Persson using a new type of scan known as dual energy computed tomography (DECT) angiography, in which a patient is scanned using two sources of X-rays at different energies.

The issue appears bigger than expected, according to Metasploit maker HD Moore’s presentation at AusCERT2013. His research also revealed that more than 75 million devices all over the world are vulnerable to SNMP (Simple Network Management Protocol) design flaws, such as the connectionless SNMP over UDP. Since these devices are highly specialized, they never run antivirus or other kinds of intrusion detection software, so once they’re compromised, the malicious activity goes unnoticed. When he is not documenting sophisticated strains of malware or writing removal tools, he teaches extreme sports such as surfing the web without protection or rodeo with wild Trojan horses. Well, instead of calling it as merely a combination of hardware and software, it would be apt to define it as application specific, organized hardware, controlled by specific software in which the hardware and software are the components of the embedded system. And the software components constitute programs such as compilers, integrated development environments (IDE), assemblers, simulators etc., which are used to create codes that “instruct” the hardware to do the assigned job in an efficient manner. Most notable among them are, 8051 from Intel, PIC series from Microchip, AVR series from Atmel, 68HC11 and HD44780 LCD controller from Hitachi.
Embedded computer systems differ from general systems in that they are designed to perform a single task and are only ever intended for one specific purpose.
The standard way to compare processing power is by millions of instructions per second (MIPS), and a higher rating indicates a more powerful processor. A 16-bit processor can support a maximum of 65KB of RAM, whereas an 8-bit processor can address only 256 bytes. Your network may consist of a just one single board computer or hundreds of different components. If you plan on upgrading your system regularly, then longevity may not be a factor in your decision, but if you only plan on purchasing your hardware once you will need to find a system that will stand the test of time.
Embedded systems in anti-lock brakes must work 100% of the time, but a system for an electrical gadget used for entertainment purposes may not have to be so reliable. Once set up, embedded systems will perform their task without the need for much prompting, so it is worthwhile investing a good deal of time in choosing the right components for the job. Few simple electronics circuits can be intelligently hardware designed without a microprocessor or microcontroller but is not worth the economics except for simple passive operations.
Stellar Edge has selected 23 students through PTU who shall be doing their Industrial Training at Stellar Edge,Chandigarh. Designers save implementation effort with an easy-to-use flow from RTL generation to instantiation in the HAPS system, using the same RTL from design through validation. Never before have I thought of a kidney stone or a nit as beautiful but the Wellcome Image Awards show time and again that there can always be a different way of looking at things."The winning images will be displayed at four major science venues as well as in a window display at the Wellcome Trust's headquarters in London. He believes that most things in life can be beat with strong heuristics and that antimalware research is like working for a secret agency: you need to stay focused at all times, but you get all the glory when you catch the bad guys. And there are many versions of the definition of embedded system which ultimately culminate as said above. Notable computer languages that are used for programming in embedded systems are embedded C, embedded C++, embedded JAVA and assembly. The microcontroller integrates many useful components such as memory, timers, counters, ADC, DAC etc onto the same package along with the controller. The PIC controllers are mostly used by hobbyists.  Some examples of the embedded system worth mentioning are, cell phones, air conditioner, car dashboard control, PMPs, robots, scientific calculators etc.
Pls try to make it understandable & usable for even those who are not very strong in mathematics too.

They can be utilised for the most basic of tasks such as a 4-bit processor in a digital watch, or they can be used for the advancement of mankind as a component in a complex system such as the Mars Rover.
You will also need to take into account the amount of space you have available, your budget and amount of RAM needed to run your software. So it’s more or less must to put this so called silicon brain, which we engineers call as microcontroller in all electronics systems.
This PC system’s architecture is designed for application such as net surfing, excel, word, PowerPoint, and you know the rest!
Application-specific instruction-set processors (ASIPs) are essential for meeting the power efficiency requirements of system-on-chips (SoCs) supporting high-performance embedded vision applications, such as advanced driver assistance systems (ADAS), augmented reality (AR), robotics, surveillance and gesture control.
The execution of the compiled code with the automatically-generated instruction-set simulator (ISS) is easy to profile, clearly identifying performance-intensive parts of the application, which can be accelerated by changes in the processor architecture, including memory access, register configuration and instruction set.
As a leader in electronic design automation (EDA) and semiconductor IP, its software, IP and services help engineers address their design, verification, system and manufacturing challenges. Glasgow Science Centre, the Museum of Science and Industry (MOSI) in Manchester, Techniquest in Cardiff and W5 in Belfast will all host simultaneous exhibitions, and there will be a display at the Ruskin Gallery at Anglia Ruskin University in Cambridge during the Cambridge Science Festival. In contrast, for a microprocessor, timers, counters are to be provided separately and memory should also be interfaced separately which involves some additional circuitry and again which eats more space.
When designing an embedded system there are seven requirements which must be considered by the user, and this article examines each one in detail. The new Synopsys Embedded Vision Development System enables designers to rapidly explore and tune processor architectures for the optimal combination of power and speed, and quickly implement the design on a HAPS FPGA-based prototype.
Unlike configurable processors that rely on a fixed pipeline and register structure, this methodology removes limitations from achieving the most power- and performance-optimized custom architecture for their application. Running more than 100x faster than a cycle-accurate ISS-based model, the combination of Processor Designer and HAPS in the new integrated design and prototyping system provides a highly-efficient way to refine and validate ASIP architectures from project to project.
Since 1986, engineers around the world have been using Synopsys technology to design and create billions of chips and systems. Multiplication is repeated addition, subtraction is addition of negative numbers and division is repeated addition of negative numbers.
This field of designing application specific computer systems is called embedded systems development. Mostly, for simple applications, assembly is used, which produces more efficient, compact codes. If the response of this computer system need to be real time and highly reliable then it’s called Real Time Embedded System. Of course you can implement the same cell phone with a microprocessor, but it takes too much space and also as much circuitry is involved, more power is consumed.] But microprocessor is designed for a general purpose. Same microprocessor can be used for designing an automatic washing machine and also a cell phone, but that’s not the case with microcontrollers, its specific for a specific device. On summarizing, we can roughly refer the microcontroller as an enhanced microprocessor, enhanced for a specific task.
