In the present date any embedded system cannot be imagined without VLSI design. At the same time a high end VLSI design will be successful if it is running a properly designed software. I would compare them as complimentary domains, like tea and sugar. Embedded system is the tea and VLSI is the sugar.

First of all, it's foolish to ask "which one is better?". You're a project lead at TI, so you shld know, these technologies are complementary. A typical embedded system has VLSI components integrated into it. Going bit further we can say there 're no embedded systems without VLSI. Yes, everything can be done inside VLSI .. but it's non-cost-effective & inflexible.

However, the 2nd part of the "debate" .. which field has a better future seems a valid point to discuss. Here're my 2 cents -

1. Embedded systems is a more interesting field, as it sits on top of everything. You get a bird's eye view. VLSI is the core part though. It's a top priority that the VLSI design is perfect, as the whole system depends on it. If you're in the VLSI team, you know the system in & out. However, the embedded engineer (mostly, people who write assembly or low-level code that control the VLSI chips) may not be aware of what goes on inside the chip.

2. If you're an embedded systems engineer & you're sitting in a meeting room with a few VLSI engineers, it'd often happen that you're sitting there sheepishly .. without getting head or tail of what they're talking. It's not true the other way round.If this fact may hurt your ego .. I'd say .. go for VLSI.

3. However, if you're more of a practical guy, you'd go for embedded systems. Fact is, most of the semiconductor companies hesistates to relegate their VLSI design jobs to India. As I said, it's the most important part of the whole system & they want it to be done at home .. by competent engineers. If you're in India, probably you'd be reporting to an American boss, & most of your work will be peripheral. Compared to that the embedded systems guy would have more freedom to work. They trust Indians at the coding part. Your team might be handling the core parts of the firmware development work. So .. if they have to lay off a few guys .. the VLSI guys will be the first ones to go. This may not be the truth if you're actually sitting in the head-office in the US. I'm talking only about the guys in India or other out-sourced countries.

At the end of the day .. you gotta decide for yourself. I'm voting for embedded systems though, because I'm sure if you love the job, you won't feel sheepish in that meeting room.. you'd do some back grnd study & come up smarter in the next meeting at least..

BACKEND for the EMBEDDED processor also done only by VLSI. IN front end only both are different(by programming language) speed of the VLSI processor high, but speed of the I/O access is high for embedded processor.

vlsi is toughest and rarest knowledge which we cant touch but we can fee it in india it vast developin technology

I do agree that both streams are complimentary for each other.If you consider the challenges in Embedded systems like low cost,low power with more and more features,without VLSI we cann't achieve it.It is true that software/firmware gives flexibility to exploit hardware capability,but still there are some piece of codes running in the system,which have to be avoid to save power.So hardware(i.e SoC) has to be intelligent enough to save power.As for as low cost is concerned,we can save cost by reducing die size.

VLSI is Very large scale integration as you would have already known. Now VLSI refers to a manufacturing technology. it basically tells you that a chip has a big number of transistors fabricated on a unit area. Embedded system refers to a system which has software and hardware at a miniature scale. Like PDAs, microwave ovens, washing machines all of these things have some hardware and embedded software. Actually you are comparing apples with oranges. both are fruits but they are different..

i am fresher..would like to join EMBEDED. vlsi is in saturation. EMBEDED is good for hardware as well as software.

I would like to think Embedded systems as practical usage of VLSi chips in day to day life .It certainly gives you the bigger picture of what all can be possible with powerful microprocessors and the supporting software.

This felid surely has a bright  future.

as said both are different fields altogether, but for future concern i suggest Embedded will be having the bright opportunities.

Now a days the VLSI reached some stage like saturation as the processors are powerful and can deal with complex problems having small size.

as we can see, no embedded application developed till now is able to use full speed & features provided by these advanced chips, the embedded applications become like bottleneck on the processors, so in future i can see more robust & platform specific firmware is needed that provides growth for embedded than VLSI.

Embedded System is generally referred to system that involve micro controller/microprocessor. Micro controller is the core of embedded system, and whats inside it is VLSI design.
