The pattern I have observed in my friends and myself (when I was on dating apps) goes something like this: We get matches, some of those matches flake, don't respond, or don't pan out into anything. So we mitigate that emotional r

One thing that doesn't sit well with me about most dating apps is that they operate under the paradigm where "If you're attractive, you're the product, not the customer" If you're getting likes, or swipes, or m

Full Disclosure, I work for an FPGA company. The mind blowing part of all of this is the fact that they were able to close timing at 771MHz. That is insanely fast for an FPGA. For perspective, most modern FPGAs run their designs at around 3

Since so many people are asking what "emulation" is, I'm going to respond to the parent comment instead: "Emulation" refers to emulation of chip designs. When a chip has billions of transistors that are all connecte

I think this alternate future of a gigantic CCS network is a really long ways off. Have you ever tried to use non-Tesla DC fast charging? It's a mess! There aren't a lot of stalls, one of them is usually broken, and the payment pr

I have a tinfoil hat theory that all of this environmental and safety regulation was amplified heavily by lobbying and/or propaganda efforts from the coal companies. On one hand, you can make the argument that nuclear fuel was the new

These are really good questions to be asking, and to help with that let's consider 3 attributes of compute complexity: time, space, and memory The traditional way of computing on a CPU is in essence a list of instructions to be compute

Probably some Physical Design engineers who looked at the problem, and realized that it was a complex geometry problem that could be sped up buy parallelized computing. So they called up Synopsys (probably not TSMC) and were like "can

I would offer a counter point: Chat GPT uses text, which is analogous to the MIDI of spoken language. Now, what's to prevent a speech to text and text to speech AI slapped on both ends to make it audibly conversational? Or train the fr

One of the difficulties of open sourcing bitstream generation of an FPGA is not the fabric itself, but all of the other IPs on the chip. Things like PCIe, Ethernet, memory controllers, SerDes and whatnot are often licensed from external ven

Did Synopsys design the DDR5 controller by any chance?

Pretty much, but I'd change the dimensions of the graphics card to match mini ITX, and so that it could be bolted to the case. This provides two benefits: It can support a bigger and heavier heatsink and it also allows you to spread th

> Should we have GPU VRAM slots alongside CPU RAM slots? Is that even possible? I chuckled a little at this because I used to wonder the same thing until I had to actually bring up a GDDR6 interface. Basically the reason GDDR6 is able to

While you're correct that overall system cost is what matters, most functionality is offloaded to the controller because a single controller often controls multiple DRAM chips (Like the chips all share a CA bus[1]) So it's cheaper

So this is really cool and useful, but it's important to keep in mind that since this is a diffractive structure, it probably only works with coherent light (what you get from a laser.) Most normal light sources produce incoherent ligh

I would imagine that you generate the desired transform function of a diffractive structure rather than the structure itself, because the structure is ultimately derived from the transform function. Since the transform function is basically

by Lramseyer 4y ago
Sort of, I didn't dive too far into the math, but it looks like each diffractive structure is akin a layer of a neural net, which is tuned for a set of spatial frequencies and phases, which when combined (like layers of a neural net) t

This is really great, because it touches on the concepts of hardware design. I've thought a lot about this myself, and I'm honestly surprised to see someone else discussing this. Maybe I'm way out of my depth here, but the id

Well I'll be... Though the renderings indicate that this is a CXL controller connected to DRAMs on the back end. It makes sense, since the front end logic for CXL is die area intensive. This is basically an SSD without all of the compl

Doubtful. PCIe Gen 5.0 x16 over DDR5 is a huge cost increase, a huge latency increase, and only a minor bandwidth increase (about double after accounting for protocol overhead.) At that point, you might as well widen your memory bus and use

I think there are a lot of misconceptions here in other sub comments. For starters, the DRAM manufacturers may possibly be the biggest penny pinchers in the semiconductor business. They're too cheap to use differential signaling even o

You can with enough money. Usually you see ground traces and ground planes separate high speed data buses. The problem is that the more layers you have, the more expensive it is.

The risk averse nature of the semiconductor industry comes from it's financial scale and speed. If there's a mistake, re-spinning the chip (even just the metal layer) is costly both in time and financially. No self respecting semi

Fun fact: The dimensions of a magnet (a bit of data) on an HDD are actually rectangular. It's about 3-5x wider than it is long. This favors read/write speed, since you cover more bits per rotational length. Aside from the obvious

I used it a few years back, but for me the color temperatures never scaled right. I like my lights at 4500-5500K during the day, but it looks a little too warm on my monitor (f.lux defaults daylight to 6500K.) Maybe it's my lights&#x2F

You know, it wasn't long ago that Blender was a somewhat obscure open source CG/3D modeling software that was not taken super seriously for enterprise use. Blender has been around for a really long time, and there has always been

Yes, but assume that they're cherry picked. Don't get me wrong, these numbers are impressive, but it claims that it's GPU is faster than the highest end discrete GPU (RTX 3090) but it's unclear on what benchmark it used.
