Upmem’s Processor-In-Memory Accelerates AI

“A clear conscience is usually the sign of a bad memory.” – Steven Wright
It’s a DRAM module, right? Well, that’s only partially correct. It is a standard DIMM (dual inline memory module), but it’s also 128 microprocessors. Don’t see the sea of CPUs? That’s because they’re coming from… inside the housing! … Read More → "Upmem’s Processor-In-Memory Accelerates AI"

Loading Software on the Fly: AppStreamer

“Those who do not learn from history are doomed to repeat it.”  – George Santayana

I swear, people are trying their hardest to resurrect the 1970s. I thought the era of bell-bottom pants, 8-inch floppy disks, and bicycles with banana seats was nostalgia-proof. Yet here we are. First there was cloud computing, a throwback to the days of dumb … Read More → "Loading Software on the Fly: AppStreamer"

Hey Max, So, so far we have been asking ourselves this question: for how long after a press or a release does the switch exhibits bouncing? Or rephrasing the question a little bit: What is the longest time for which a switch exhibits bouncing after a press or release? Now, ...

I haven't debounced a switch in hardware in more than 30 years. My designs always have a MCU of some sort in them and I've always had an available pin and processing time to implement a debounce routine. I vastly prefer that route, as I can change the algorithm as needed ...

Hi Max, I guess there can never be enough discussions about de-bouncing. To add my contribution to the naive questions... Suppose we have a signal flow as below: 4 banks of 8 switches (24V )---> Optoisolation ----> Latch (74HC573 perhaps) -----> Port of uC (8051 perhaps) Does it matter where ...

Max, I'm enjoying this series very much. Debounce is one of those things you always will have in any project. In FPGAs, bouncing inputs can wreak havoc in your FSMs and find nasty bugs in your sequential logic. Sometimes you have to group switches that are related (like multipole switches) ...

Very interesting -- thanks for sharing -- in fact I'll be talking about using an OR of multiple switches to trigger an interrupt later in the series -- but it's interesting to hear that someone successfully used a monostable in a switch debounce scenario
Posted on Feb 13 at 9:28am by antedeluvian
just an addendum to your comment “The bottom line is that I would be hard pushed to come up with a reason to implement a switch debounce solution based on a monostable multivibrator.” In my very early days I was implementing a 16 switch keypad to binary- the hex keypad had 16 ...

Thanks for bringing OpenCAPI into focus here Christoforos! Kevin, I'd highly encourage that you extend this very interesting article by bringing OpenCAPI into the fold. As someone involved in attaching coherent busses to FPGAs since 2007, with both Intel and IBM, I can attest that it is a history worth telling ...

Thank you for reply Max. I am looking forward to next article.
Posted on Feb 12 at 1:33pm by Max Maxfield
Hi Pavle -- thank you so much for your kind words and also for pointing me at this solution on the Digi-Key website. As you say, what you start off thinking with be a trivial problem quickly becomes... let's say "interesting" -- I'm currently working on the next article in ...
Posted on Feb 12 at 8:14am by Pavle Tsotskolauri
Hi Max When I was studying FPGA design in University My lecturer told me to create pushbutton debounce design. First , I thought that this would be trivial problem and I could finish very fast but then I found out that this is serious problem that needs to be address in ...
