Metrology Maketh the Man (and Woman, and Silicon Chip)

Metrology is the scientific study of measurement. The ability to measure things helps in locating and identifying problems and weak spots in production lines and processes. I was just introduced to a new molecular sensor for semiconductor metrology that may be poised to take the chip fabrication process by storm, but first…

When we look around, it’s easy to … Read More → "Metrology Maketh the Man (and Woman, and Silicon Chip)"

Xilinx Launches Versal HBM

It’s no secret that we are drowning in data. Today’s applications and algorithms require almost incomprehensible amounts of data, and that means the bandwidth requirements are exploding faster than networking and memory technologies can handle. Even with the most advanced accelerators we can build with our FPGAs, we can be choked trying to get data on and off the chip and finding places to … Read More → "Xilinx Launches Versal HBM"

Quadric CPU Combines AI with Conventional Code

Another day, another new microprocessor architecture. There was a time in the Nineties when everyone and his dog was designing a new processor. They were all going to revolutionize the world, crush Intel, enable new cutting-edge devices, and show us how it’s really supposed to be done. The nerd journals were filled with new CPU acronyms like RISC, VLIW, IPC, EPIC, ROB, ILP, SSE2, TLB, … Read More → "Quadric CPU Combines AI with Conventional Code"

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.

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?"

Configure the charge and discharge current separately in a reversible buck/boost regulator

Sponsored by Maxim Integrated

The design of a front-end converter can be made less complicated when minimal extra current overhead is required for charging the supercapacitor. This application note explains how to configure the reversible buck/boost converter to achieve a lighter impact on the system during the charging phase. Setting the charge current requirement to the minimum amount keeps the discharge current availability intact.

Could it be that the wrong types of computational machines are being used, i.e. a stored program model? C/C++ software models are being developed that program an FPGA directly, but converting this model to a computational machine is difficult. The advantage of this model though, is that the ...

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 ...
