Embedded Systems/VLSI

Greetings,
First of all you should know what you are approaching, embedded systems is loads of programming, where 128 mb is still lots of RAM in that universe of embedded programming. So if you are Interested in loads of coding where you want your software to affect your physical things and whats happening at the bottom of the architecture then you are at the right place, so get prepared. First check out that there are many good hobbyist embedded platforms available now (Arduino, Raspberry Pi, Particle, etc). They have lots of great communities to participate in and learn from. So you get the idea of whats going on. Now, on to your question, after BCA you will only have some programming skills, so its better you start working besides doing your course BCA whenever you get time. You can start with communities which I have mentioned above as they will give you a clear picture.
1) Learning of C
2) Learning of Basics Electronics important [you just need a basic understanding of voltage, current, power, resistance, ohms law. You probably can get by with just a few online tutorials and some experimenting with online simulators and/or real circuits.].
3) Get the EQUIPMENT soldiering iron, digital multi-meter and A hardware debugger/ JTAG adapter (such as an ST-Link, or OLMEX adapter),
4) Choose your Micro Controller and tool chain, so now you have all the fundamentals and you are ready to code. If you are interested in all of the above, you are on right track. If all of the above doesn't match with your interest, get a normal professional training after BCA like a training in SAP/Networking/JAVA.
Thanks!

There is scope in every field. You must opt for the one which matches your interest and skills as it will help you to achieve your long term career goal.
1) VLSI :
* If you are planning to begin a career in the semiconductor industry then you must have a sound knowledge of jobs and growth opportunities in the VLSI domain. The VLSI industry is growing at a fast pace and requires skilled professionals.
* Some of the companies which employ VLSI professionals are :
-Analog Devices
-Cadence
-Synopsys
-Cypress Semiconductor
-HCL Technologies
-Texas Instruments (TI)
-PMC Sierra
-Alliance Semiconductor
-Intel
-Micron Tech
-Philips Semiconductor
-Qualcomm
-Wipro
-EInfochips
* Salary :
Salary depends on various parameters such as size of the organization, profile, qualification, experience, etc.
But, still, to give you a brief idea, as a fresher, you can expect a salary of up to Rs 15,000 to Rs 25,000 per month.
PG students can earn up to Rs 20,000 to Rs 40,000 a month.
As an experienced professional, you can expect to earn Rs. 50,000 to 1, 00,000 per month.

2) Embedded Systems :
* An embedded system is a computer system designed for specific control functions within a larger system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts.
* There is good scope for the electrical and electronics students because many MNCs are hiring the students mostly on the background of embedded systems course as this course is very important in the electronics field.
Scope is in Communication, Industrial Tools, Medical Equipment, Power Electronics, Control System.
* As far as scope and salary is concerned, it depends on you. If you have interest in the field then you may get promoted and enjoy the benefits of getting promoted with increased salary.
