ChatGPT will not replace me – yet

An EEJournal reader recently suggested, eagerly I might add, that ChatGPT can already replace me. This statement was made even before OpenAI announced ChatGPT 4o. It’s not something that particularly worries me, knowing how these chatbots are trained. You can try to dump the entire Internet into a chatbot training session, but that does not give the chatbot wisdom, nor will it transform the chatbot into … Read More → "ChatGPT will not replace me – yet"

Building A Semiconductor Fab? I Have Awesome News (Exclamation Mark)

I’ve been informed by the punctuation police that I am no longer allowed to employ exclamation marks in my column titles. That’s like asking me to write while hopping up and down on one leg with one arm tied behind my back, but I’ll try to be brave and soldier on. Suffice it to say that for anyone building a semiconductor fab who wants … Read More → "Building A Semiconductor Fab? I Have Awesome News (Exclamation Mark)"

Awesome Retro Displays and Computers

In retrospect, it’s been a funny old day with respect to retro displays and computers, starting with Numitron tubes (which use seven incandescent filaments arranged to form a seven-segment display) and ending with an 8-bit computer implemented using 1950s thermionic valves (vacuum tubes).

Now, I want you to be honest with me… am I alone in loving the technologies of yesteryear? For … Read More → "Awesome Retro Displays and Computers"

DNA of a Modern Mid-Range FPGA

Sponsored by Intel

While it is tempting to classify FPGAs simply based on logic capacity, modern FPGAs are alterable systems on chips with a wide variety of features and resources. In this blog we look closer at requirements of the mid-range segment of the FPGA industry.

Larsen & Toubro Builds Data Centers with Effective Cooling Using Cadence Reality DC Design

Sponsored by Cadence Design Systems

Larsen & Toubro built the world’s largest FIFA stadium in Qatar, the world’s tallest statue, and one of the world’s most sophisticated cricket stadiums. Their latest business venture? Designing data centers. Since IT equipment in data centers generates a lot of heat, it’s important to have an efficient and effective cooling system. Learn why, Larsen & Toubro use Cadence Reality DC Design Software for simulation and analysis of the cooling system.

You made me grin, traneusee. I've always used center-tapped transformers to build symmetric + and - power supplies, mostly with 24 VCT transformers, but I'm sure you've described the original intended use. I was born too late to worry about gaseous FET heaters.

Back in my day we didn’t have all that mamby-pamby tool software stuff. We had to grab the wafer while it was still red-hot from the furnace and beat it flat enough for the next guy in line to work on - The lithographer… If you needed pure air ...

VCT rating on a transformer secondary meant "volts center tapped", the voltage across the whole winding. The winding has a tap (third lead) at the center of the winding. A 6.3 VCT transformer was intended to have 6.3-volt vacuum-tube heaters connected across the ends of the winding. The center tap was ...

Rather than build an entire computer, I really would like to build a "2-core" ALU -- one core out of relays and the other out of vacuum tubes -- mount them in class-fronted cabinets on the office wall -- and have them performing calculations in parallel just for the heck ...

Right on, Steve! However, the current soft processors are just too slow and embedded processors are at the limit of clock frequency. By the way, Stratix FPGAs have impressive embedded memory blocks with true duel port mode. Meaning that it can write the result of the previous cycle and read ...

"I mean to say that (decimal, floating point, and vfl) were not included. That essentially meant that it did add, subtract, compare, load, store, branch. Same as the older 7044. The 7044 had index registers that were offsets to operands. System 360 had 16 General Purpose registers, but most were used for addressing data ...
