BASIC GATES USING 2:1 MUX

The following post shows the implementation of basic gates using 2:1 mux! 

It helps often in written tests and interview process! 

The idea can be extended to implement other logics like full adder, half adder and also to multiplying logic! 

The New Found Self-Confidence

               There was a business executive who was deep in debt and could see no way out. Creditors were closing in on him. Suppliers were demanding payment. He sat on the park bench, head in hands, wondering if anything could save his company from bankruptcy. Suddenly an old man appeared before him. ”I can see that something is troubling you,” he said. After listening to the executive’s woes, the old man said, “I believe I can help you.” He asked the man his name, wrote out a check, and pushed it into his hand saying, “Take this
money. Meet me here exactly one year from today, and you can pay me back at that time.”

Then he turned and disappeared as quickly as he had come.

           The business executive saw in his hand a check for $500,000, signed by John D. Rockefeller, then one of the richest men in the world! “I can erase my money worries in an instant!” he realized. But instead, the executive decided to put the uncashed check in his safe. Just knowing it was there might give him the strength to work out a way to save his business, he thought. With renewed optimism, he negotiated better deals and extended terms of payment. He closed several big sales. Within a few months, he was out of debt and making money once again.
Exactly one year later, he returned to the park with the uncashed check. At the agreed-upon
time, the old man appeared. But just as the executive was about to hand back the check and
share his success story, a nurse came running up and grabbed the old man. “I’m so glad I caught him!” she cried. “I hope he hasn't been bothering you. He’s always escaping from the rest home and telling people he’s John D. Rockefeller.” And she led the old man away by the arm.
The astonished executive just stood there, stunned. All year long he’d been wheeling and
dealing, buying and selling, convinced he had half a million dollars behind him.
Suddenly, he realized that it wasn't the money, real or imagined, that had turned his life around.
It was his new found self-confidence that gave him the power to achieve anything he went after.

Searching in Google

                We always looked up to google for our academic works, whether it be assignments or seminars or presentation materials or help with projects or what ever else you could think about.We could save a lot of time on googling if we google the thinks we need the right way.

   Heres one way that helped me save a bit of time finding materials on google.

             Generally we look for material in specific format whether it be doc or pdf or ppt. We could narrow down the search results by following a simple searching term.

             For example if we are looking for pdf file on specific subject like signed arithmetic. We could do it by modifying the search term to "filetype:pdf signed arithmetic " This will narrow down the search results to only pdf files that have words signed or arithmetic or both.

Heres the example

So to find doc file its filetype:doc signed arithmetic
     to find  ppt file its filetype:ppt signed arithmetic

                   

              Also there is an interesting search tool in google that is google scholar  which will help us in collecting materials for academic purpose. We could narrow down search results based on author names or title or date of publication etc.

                     Its always good to collect material from known and trusted sites rather than beating around the bush. But there is nothing wrong in spending sometime googling for it.

       

Career in FPGAs

Read an interesting article on a technical forum electronicsforu about avenue into the field of FPGAs.

For those who don't know what FPGA is - it stands for Field Programmable Gate Array(FPGA) , is an integrated circuit designed to be configured by a customer or a designer after manufacturing—hence "field-programmable".


Here are some of the highlights from the article.

            As per semiconductor industry data, the total global programmable market was worth close to $5.1 billion in 2011, with $4 billion coming from FPGAs.

            India will grow as a market for engineers equipped with FPGA skillset. In the coming years, engineers equipped with FPGA skillset will be in demand at two levels—technology/block development and implementation.

          There is scope for career in  FPGA field not only in  manufacturing of these , but also working for organisations that design around FPGAs. These include Cisco, Juniper, Samsung and Tejas Networks. Firms like National Instruments, Wipro and Infosys too have divisions for FPGA engineers.

          A professor from IIT Bombay explains the role of an FPGA engineer: “A fresher’s job will involve activities like testing, emulation and verification, while an expert in FPGA will be asked to handle digital system design, system-on-chip, embedded hardware-software co-design, digital communication sub-systems, hardware accelerators for various computing tasks, embedded control systems and digital signal processing sub-systems/systems.”

Payscales for FPGA skill sets

Some of the Institutes that offer training in this field are Sandeepani , Veda-iit , CDAC .

VLSI Training Institutes

Here I am posting some links related to the VLSI courses. I have searched on net and came to know the best opportunities available. 
            If you guys know any good institutes please mention them in comments..
