Disruption in the 1920s

“When I’m assembling a scene, I assemble it as a silent movie.” – Walter Murch

Hardly a week goes by that some “disruptive” new technology makes the news (you’re welcome) with promises to upend everything we know about computers, software, consumer electronics, security, healthcare, etc. Many of those promises peter out, never to be heard from again. But enough of them … Read More → "Disruption in the 1920s"

FlexLogix Accelerates Edge Inference

Let’s start with one hard fact. There are a lot of companies developing new AI inference processors right now, and most of them won’t survive. We have heard reports that as many as 80 startups are currently funded to some level, and all of them are working hard on building better mousetraps, or at least building better specialized processors that could execute neural network models … Read More → "FlexLogix Accelerates Edge Inference"

More Efficient Time-Sensitive Ethernet

Ah, Ethernet… our good, reliable, trusty friend from way back. So trusty, in fact, that our cars may soon be running a version of Ethernet for all of the electrification stuff. Leveraging something tried and true should certainly go without a hitch, right?

Well, certainly as compared to coming up with something entirely new, perhaps. But what’s this Ethernet … Read More → "More Efficient Time-Sensitive Ethernet"

When Tubes were Better than Transistors

“I come to bury Caesar, not to praise him.” – William Shakespeare

Way back in 1960, just after ICs were invented but before they became much of a force in the electronics market, the Electron Tube Information Council published a book titled “Tubes and Transistors: A … Read More → "When Tubes were Better than Transistors"

The Debug Time Machine

“Is this going to be a stand-up fight, sir, or another bug hunt?” – PFC Hudson, Aliens

If you’re debugging code, which tool would you rather have: your favorite debugger or a time machine? A good debugger is vital, sure, but a time machine… You could rewind the clock to before the point you inserted the bug and then… just… not do … Read More → "The Debug Time Machine"

Many of the failed projects I took over had similar problems where the original team beat their heads against an insolvable solution for months. Often because they avoided "better" "workable" solutions that they had some false idea that they were "worse" "unworkable" because "everybody" knew they were. Many times because ...

For example, I was shocked when I read the review about essayshark because I have been using this service for many years, but I accept the point of view of these people because the situations are different. For me, this service ...

A big part of what fueled my first response was WTF, why are people thinking about designing unnecessary complexity into a mission critical high reliability application? IF these folks are thinking about replacing CAN Bus with Ethernet and using it as a primary navigation sensor bus, these folks are making ...

And I'm really including that state of the art vision system (several channels of stereo vision, plus LIDAR and RADAR) back to the AI front end. When interfaces are dead cheap, you DO NOT design bandwidth critical, congestion managed links into the system. Both copper and fiber ethernet links are ...

In an automotive land where real-time events are tens of milliseconds, and $2 ethernet interfaces are 1 gigabit per second (possibly 10gbps) , it really seems somebody here is trying to sell a long unpopular bridge to nowhere.

What do you think of Excelfore's time-aware Ethernet traffic shaper?
Posted on Apr 14 at 9:54pm by TotallyLost
It would be really nice to see the I-series chips closely coupled with Xeon's soon ... especially if Intel would give researchers (and open source developers) access to enough details about the low level architecture and bit stream to do place and route. We did a pretty good job at proving ...

@Beercandyman - I have to agree. They need a fast compile-load-and-go solution that hits 80% of best case SPEED in not more than 150% AREA, using functional tiles with easy partial reconfiguration of modules. Better speed and area optimization is something to do after you have a working solution.
Posted on Apr 11 at 11:20am by Beercandyman
I don't really see anything new except better marketing from Intel. It will still take hours to compile a design. They have done nothing about their randomized routing that messes up partial reconfiguration. They offer no tools to generate a bitstream in minutes (a totally doable task). Henry Ford once ...

Let'€™s face it: We'€™re addicted to SRAM. It'€™s big, it'€™s power-hungry, but it'€™s fast. And no matter how much we complain about it, we still use it. Because we don'€™t have anything better in the mainstream yet. We'€™ve looked at attempts to improve conven...
