what is meant by embedded system? what is its future?

An embedded system is one where the computer is \nenclosed within the end-user product.  It may not\neven be obvious to a user that a computer is involved.\n\nExamples might be the numerous computers embedded \nwithin current automobiles (which control anti-lock\nbrakes, fuel/air mix, etc).  Consider the processor\nin current dishwashers, children's toys, or high-end\nhearing aids.\n\n\nYou ask, "what is its future?" -- it *is* the future.\nThe beauty of an embedded system is that it is a\ncase where the computer is blending in with *our*\nlives (ie. we just drive the car, use the cell phone,\nor run the dishwasher without having to learn how\nto deal with a computer).  Contrast this with how\nmuch we have to change, and how hard we have to work\nto deal with a computer when it is fashioned as, \nwell, "a computer".

An embedded system is a special-purpose computer system, which is completely encapsulated by the device it controls. An embedded system has specific requirements and performs pre-defined tasks, unlike a general-purpose personal computer. An embedded system is a computer-controlled system. The core of any embedded system is a microprocessor, programmed to perform a few tasks (often just one task). This is to be compared to other computer systems with general purpose hardware and externally loaded software. Embedded systems are often designed for mass production.

Nothing.\n\nA multiprocessor system IS a multi-tasking operating system.\n\nBut a multi-tasking system isn't always a multi-processor system.

Or just find a COTS solution, since such systems are already in use.\n\nIs there a question in here, such as what technology platforms might be appropriate?

Smart Sensors or Intelligent Sensors are sensors that incorporate a microprocessor or microcontroller. They usually compensate for environmental disturbances and have built int ADC's and comunications systems by digital buses. \n\nGoogle Intelligent Sensors

They are basically the same as far as language goes. The biggest difference is going to be the compiler and operating system. If you have a serial communications module written for an embedded processor, it probable wont work on your desktop/laptop, or the other way around. Mostly because of the operating system used on each.

Wireless devices will be everywhere. The phone, camera, and computer will merge with the internet. Vast databases of information will store, calculate, and notate every change everywhere. We will lose more privacy because of satellite imaging and web cameras. I know communications will become "one touch" access. The way we communicate will make the biggest changes. Look at what engineers have accomplished so far. Electronics is communication.

I had to check your other questions to figure out what you may be asking.  Machine code and assembly language are used to control machines and write hardware instructions and drivers.  There are sometimes software toolkits used relative to the hardware/OS environment you're working with.\n\nUsing C/C++, you can control machines through embedded systems.  It's quite prevalent for factory machines and robotics.  \n\nYou will find subject books by looking for the terms: embedded systems, machine code, assembly language.

Each hardware has its own software interface and supported protocol(s). You have to read manufacturer's documentation.

I deal in the embedded field on a daily basis.\n\nHard to say specifically that it is "hot", but I will tell you that there is a shortage of people that are good at it.\n\nYou require knowledge of hardware, how a CPU functions (including interrupts, DMA transfers, and timing considerations), assembly languages, real-time considerations, testing methodology, and require a strong debugging skillset. All of this, plus be a good programmer as well.\n\nSome find it exciting, some boring, it all depends on how you approach your work.\n\nHard to call it a boom really, just a lot of possibilities. Not too much is being outsourced right now, but could change in future.

Embedded Journalism Is when a reporter is actually experiencing a story and reporting live as the story progresses.\n\nIE) Reporters are embedded with Military Units in Iraq, and have strict standards... They can brodcast but cannot give away positions of the unit they are with, where they are and various other things.

The biggest one and most interesting is future alternatives to standard CMOS process technology. CMOS is predicted to run out of steam in a few years, i.e. feature size and speed will hit a limit dictated by physics not technology. What are the alternatives ?

Actually any program that could do this would be considered to have an embedded operating system. Many antivirus and system recovery programs use a minimized o/s in order to access the hard drive.

1.) More storage capacity in smaller sizes\n\n2.) Faster processing speeds - Intel recently stated that within 10 years, there will be up to 100 cores on a single processor.  Processors clocked at over 5Ghz should be possible in the next 4 years.\nhttp://www.wired.com/news/technology/0,70285-0.html\n\n3.) Transition from desktop applications to network/online applications to provide more extensive interoperability between systems.\n\n4.) Outplacement of other media devices to allow computers to become the center of every home and personal entertainment system.  No more TV, DVD, Blu-Ray/HD-DVD, Audio, etc.  All media will pass through a centralized or portable computer/device.\n\n5.) Production boom of portable devices.  Within ten years, 80% of the world's population will access the internet via a device other than a computer.  These devices will support more storage, faster processing and greater functionality as they evolve into personal communication and media hubs.\nBruce Chizen - Adobe CEO - MAX 2006\n\n6.)Everything wireless.  Peripherals have already begun working on BlueTooth and other WiFi technologies.  Wireless power supply is currently under development.\nhttp://networks.silicon.com/mobile/0,39024665,39164122,00.htm\n\n7.) Biometrics.  Computers will advance security with the addition of biometrics to recognize users via fingerprints, retinal scans and or facial recognition software.  Users will be automatically logged into their system/device.\nhttp://crave.cnet.com/8300-1_105-1-0.html?keyword=biometrics\n\nI'm sure there are lots more.  But these are some of the major movements in the industry right now.  Nano technologies and bio-technologies could also ignite new pathways for future advancedments.

Electronics, specifically electronics design, has the potential to be the next big thing after software.\n\nReasons are the same as those for explosive growth of software.
