Greetings,,

Since, this is my first post. So, let’s start with introduction of something for which, i have started this Web-Blog… ‘Embedded Systems’ are stand-alone devices in other words any electronic device that incorporates a computer in its implementation. The user of an embedded device is often not even aware that a computer is present in the device. The computer is used primarily to provide flexibility and to simplify the system design. Unlike a PC, program code is usually stored in ROM and not a hard disk drive. Typically, the end user does not develop new software for the embedded device. With advances in VLSI technology, embedded systems have become so inexpensive that they are found in most of today’s electronic devices or it is present in all appliances that have a digital interface or decision making capability or automation.. Some include an operating systems but many are so specialized that single program incorporates entire logic.

Common examples & where we find them???

An autonomous robot, cell phone, PDA, watches, microwaves, VCRs, cars or portable multimedia player are the common examples of an embedded device. High end automobiles can contain nearly one hundred embedded microcontrollers. A typical middle class household has over fifty embedded devices. For every PC in the world there are over one hundred embedded devices. All told, embedded devices account for most of the world’s production of microprocessors. As seen in Table below, embedded devices can be found in a wide array of products including aircraft and military systems, biomedical systems, cars, communications, computer I/O devices, electronic instrumentation, home electronics, industrial equipment, office machines, personal devices, robots, and smart toys. Infact they are every where around us…

What Developers Required to Know??

Embedded systems designers often face challenging design goals. Embedded systems must be reliable. Many embedded devices can’t crash, and may not be able to reboot. Software can’t be updated in many embedded devices. Many devices have critical performance & power design constraints. Some devices may need to run on battery power for long periods of time. In addition, consumer devices typically have a fast time to market on new products and are very cost competitive. Real-time constraints occur in many applications and many devices have limited memory and processing power.

• Expertise with both software and hardware is needed to optimize design metrics, not just a hardware or software expert.
• A designer must be comfortable with various technologies in order to choose the best for a given application and constraints.
• Must spend time architecting the system before you start coding.
• Some components are ready-made(off shelf Modules), some can be modified from existing designs, others must be designed from scratch.
• If you are a team then a designer must be able to communicate with teammates of various background or to know about your member’s skills.

Final Words

‘Embedded systems’ are electronic devices have processing source with some I/O’s …..

So,, finally……. are you inspired of Embedded Devices??, Do you want to create one for your own??..Well i made this Web-Blog for an Electronic Engineering Students, Embedded Developers, Enthusiasts, Programmers, here i will be posting my projects and articles appreciating others too which i would find on internet, my studyplace and keep informing about events and competitions,,,

So keep visiting www.embtrans.com and your suggestions in the form of comments would matter alot…. Thank You….
