Clever Hack Finds Mystery CPU Instructions

In the 1966 movie Fantastic Voyage, a team of doctors and scientists gets miniaturized and injected into the bloodstream of a human patient. They and their yellow submarine navigate past heart valves, battle corpuscles, and swim in tear ducts. It provides an inside look into biological workings most of us never see.

The First Emulators of Spring

It’s the season of rebirth. The sun is out. Flowers are in bloom. Birds busily build nests while semiconductor verification teams emerge from their long winter hibernation, ready to tool up for the challenges of the next process generation. Billions of unverified gates give shelter to countless bugs awaiting anxious design teams as they prepare for summer’s tape-outs and struggle to bring new software … Read More → "The First Emulators of Spring"

Parsing Google v. Oracle: What’s It Really Mean?

It’s okay to duplicate an API, even if you have to snarf 11,500 lines of somebody else’s code to do it.

That’s the gist of the ruling from the United States Supreme Court in the long-running case of Google v. Oracle. Left unanswered is the larger question of whether software is even protected by copyright in the first … Read More → "Parsing Google v. Oracle: What’s It Really Mean?"

ID for the IoT? We Need the IDoT!

When most people hear the term “counterfeiting,” their knee-jerk reaction is to think of currency, the counterfeiting of which is as old as the concept of money itself. Around 400 BC, for example, metal coins in Greece were often counterfeited by covering a cheap-and-cheerful material with a thin layer of a more precious metal.

Or take the original American colonies. Throughout northeastern America, Native Americans would employ shell … Read More → "ID for the IoT? We Need the IDoT!"

ARMv9: Fashionably Late

Silicon Valley is like Milan. One is the US center of high tech, the other is the fashion capital of Italy. The Valley has its product rollouts and Milan has its runway shows. Both are glamorous, slick, professionally produced events designed to generate excitement but tell you almost nothing about the actual product. They’re teases; entertainment for the press corps documenting the industry’s every … Read More → "ARMv9: Fashionably Late"

RedBarn, I agree that companies need to overhaul their "software supply chain" so that upgrades are safe and from trusted sources but that's not the market this device serves. Your internet Modem is a great example - unless you expect that updates will be delivered in physical form like a ...

This sounds like a big win for open source. Anyone can take any interface copy it word for word. How will Google feel when someone open sources all of it's APIs? Are they going to get behind a "Free Android" version? Maybe all the phone companies will get together and ...

As a guy who teaches and gives away his work (code, circuits etc.) for free for anyone to use and copy, I can understand why copying the structure of an API would be fair use, but I can't find any logic in saying that copying the actual implementation of said ...

Hi Jim, really interesting article this. It gives a really valuable insight into the way the courts think about these issues. Interesting also the bit about deferring any ruling on copyright rules. Hmm. Thank you.

Hi Chuck, I also believe in the "right to repair" but as with all technologies it is all about how you use the technology. If you buy a product from me - it is your product and belongs to no-one else. I have a smartphone, which although I paid for ...

That would be pointless - because the cloned product would be built without IDot. This only has value is preventing counterfeit consumables and/or preventing the substitution of subassemblies. So not only can you not use anything but an Official HP printer cartridge for your HP printer (even if you ...

Unfortunately, this is all too likely to be used in ways to eliminate the ability for consumers to have devices repaired. The hard drive from a MacBook with a damaged logic board won't be usable in a different MacBook with a bad drive because the "id doesn't match". Individual IDs ...

Okay - fat fingers here again. Never one to waste the opportunity to download a datasheet - short form now residing in my security products folder. I am more used to seeing Infineon in the automtive market where they have an ethos of robustness and reliability. I have used their ...

Aaaaaarghh! Did I really say WITH! Of course I obviously meant WITHOUT! Thanks Max. Well spotted - fat fingers on the keyboard moment! We currently use a device from the Maxim family of secure authenticators. The packaging isn't as small as the IDoT but on our board that isn't an ...
