How Many Computers Are in Your Computer?

It’s computers all the way down. We know about recursion in software, but it’s surprising to find it occurring in hardware. How many computers are really inside your computer? One? A couple? Maybe a dozen? In reality, it’s probably hundreds. 

Normal people count the average PC, Mac, or Linux box as one computer. But, as engineers, we … Read More → "How Many Computers Are in Your Computer?"

The Hidden Security Risks of Automotive Electronic Systems

What comes to mind when you think of an automotive energy source? I’m guessing of all the things you could possibly imagine tamarind shells wouldn’t be one of them… but maybe they should be. To start things off in this week’s Fish Fry podcast, I take a closer look at a new multi-national research study that could pave ways to supply energy to cars. (Spoiler Alert: … Read More → "The Hidden Security Risks of Automotive Electronic Systems"

If You Can’t Trust TrustInSoft, Who Can You Trust?

If you are a hardware design engineer, you are doubtless familiar with the concept of formal verification as it applies to hardware design, but have you ever considered how formal verification might relate to software and the developers thereof (bless their little cotton socks)?

Life can be a rum old thing, and no mistake. When it comes to formal verification, … Read More → "If You Can’t Trust TrustInSoft, Who Can You Trust?"

Fish Fry Special Edition: Makers Today! Lorraine Underwood

We look at science as something very elite, which only a few people can learn. That’s just not true. You just have to start early and give kids a foundation. Kids live up, or down, to expectations.” – Mae Jemison

Bluetooth AoA, AoD Find the Way Indoors

I’m sure Harald Gormsson (ca. 910–985) never saw this coming. The wireless specification that bears his nom de guerre has been extended, amended, and adapted to encompass all sorts of new applications. What began as an excuse to wear a wireless earpiece is now a way to connect to our cars, stream music to our speakers, … Read More → "Bluetooth AoA, AoD Find the Way Indoors"

Turning Flat Images Into 3D Scenes

If Elon says it, it must be true. Autonomous vehicles don’t need no steenkin’ lidar sensors. We can do it all with cameras. A nice idea, but converting camera images into useful data in real time is tricky. Very tricky. 

Cameras are stupid, mostly because they operate independent of one another. They have no spatial awareness, no concept of … Read More → "Turning Flat Images Into 3D Scenes"

Accelerating Physical Verification Productivity Part Two

Sponsored by Synopsys

Physical verification of IC designs at today’s advanced process nodes requires an immense amount of processing power. But, getting your design and verification tools to take full advantage of the compute resources available can be a challenge. In this episode of Chalk Talk, Amelia Dalton chats with Manoz Palaparthi of Synopsys about dramatically improving the performance of your physical verification process.

Configure the backup voltage in a reversible buck/boost regulator

Sponsored by Maxim Integrated

This application note looks at a reference circuit design using Maxim’s MAX38888, which provides a supercapacitor-based power backup in the absence of the system rail by discharging its stored charge. The backup voltage provided by the regulator from the super cap is 12.5% less than the system rail when the system rail is removed. This note explains how to maintain the backup voltage within 5% of the minimum SYS charge voltage.

As an extra little snippet, EEJournal's very own Amelia Dalton just emailed me to say: "I know the Uni-piper (Darth Vader playing the bagpipes)! His kids go to my son's old school. Portland is such a small town. :)" I tell you; the whole "six degrees of separation" (and "six degrees ...

As requested, below is a video demonstrating the same experiment from the Zynq MPSOC video, but targetting a high perfromance x86 CPU (AMD Ryzen ThreadRipper 16 core 3.4GHz) attached to a Xilinx Alveo U250 PCIExpress card (Virtex UltraScale+ VU13P device). As you can see everything pretty much scales with the ...

I guess this is great news for somebody but do we really need it? I believe that US patent 10,181,003 obviates the need for Boolean or State structures to solve any computation that has a solution. The asynchronous model described by US 10,181,003 synthesizes the parallel model to hardware without these structures ...

Karnaugh maps! My CompSci professor in college marked my answer as "wrong", as I didn't "do the work on the paper." As you mentioned, once you are used to these maps, you can "see" the answers. I love logic questions, and to me it was a breeze to see on ...

The article fails to mention that the only thing that is being discontinued is the old (2013) version of the SmartThings hub. Since Samsung acquired SmartThings, they gave ample warnings about eventual changes to the Hub and the entire 'ecosystem', so no one should be caught unaware. The next version of ...

OpenCL is a low level hardware API, that although technically C/C++, that does not make it easy to use, even for hardware savvy programmer. It looks like writing low level drivers. You must manually partition code, and write host-side software to communicate at the byte level to the accelerator ...

Great post! How does this compare to, for example, OpenCL which can target cpu/gpu/fpga ?
Posted on Jul 6 at 5:02pm by GregD
I'm afraid I cannot agree that OpenCL implementations are "very easy to use." First of all, the major problem with working with heterogenous compute systems is making the architectural decisions as to what code will run on the host cpu and what will run on the accelerator. That literally is ...

IMHO, Samsung has done the ultimate disservice in this respect. My Samsung Gear S, which was their first wristwatch capable of hosting its own cell phone and data plan is now a brick. First, Verizon opted to no longer accept them, as they're dropping G3 level services. So, bye bye ...
