Never heard of SuperH. I see it has branch delay slots, which is a seemingly clever but terrible idea. It's one of the reasons RISC-V quickly overtook OpenRISC in popularity I think. Not having anything that stands out is perhaps a goo

Which is exactly the right trade-off for embedded CPUs, where RISC-V is most popular right now. If desktop/server-class RISC-V CPUs become more common, it's not unreasonable to think they'll add an extension that covers the n

> I am sorry but saying that RISC-V is a winner in code density is beyond ridiculous. You have no idea what you're talking about. I've worked on designs with both ARM and RISC-V cores. The RISC-V code outperforms the ARM core,

Yeah, I'm not sure he takes into considered compressed instructions, which can be used anywhere, rather than being a separate mode like Thumb on ARM. Fusing instructions isn't just theoretical either. I'm pretty sure it is or

The thing is that Apple is kind of moving towards making RAM the level 4/5 cache. It’s becoming more and more important to tie RAM closely to CPU to reduce power consumption and lower latency. That’s naturally going to make RAM size gr

My new door has a mechanism where you first have to pull the handle up to engage this hook-like bolt and then lock the door with key or knob. I thought it was a bit tedious but now I finally understand the purpose. The bolt would prevent th

I gotta imagine that the low efficiency can be managed by using batteries whenever possible. There’s already a hybrid ferry in Norway that uses batteries for the first and last part of the trip to avoid emissions near land. Would be perfect

I'm all for pushing for more right-to-repair, but I'm not sure pushing for facilitating component level repair that require soldering is the right way to go. Those kinds of repairs are incredibly difficult (I've done some mys

That's not true. BLE can stream music now, it's in the Bluetooth 5 standard. The nRF52 isn't great for it, there's nRF53 for that, but it's possible https://www.nordicsemi.com/News/2020/01&

There's probably not enough RAM. (64kB vs 256kB for the nRF52840). Certainly not for the full resolution of the display with color. But I'm sure a more basic port would be possible.

Have you tried a Bluetooth 5 LE headphone? It's a completely different radio and protocol from previous generation Bluetooth headphones. I don't know if there are any in the market yet. There certainly isn't any based on nRF5

Wasn't many of the reactors shut down in Europe in need of being decommissioned anyway? You shouldn't run a nuclear reactor forever and ever, and most of the reactors in Europe are quite old. I know there are cases of decommission

Two issues with that - Does it actually lead to higher sales? If not, nobody is going to care about our wish for more companies to do this. - It doesn’t work for many products. How do you just drop someone into a cloud storage product? You

D has garbage collection (though it can be avoided, but perhaps everyone isn't aware of it, or maybe it doesn't have enough benefits then), which I think some game devs want to avoid. Rust is complicated by its very strict memory

Music visualization is really underdeveloped in my opinion. I've never seen anything I find impressive. The problem is it never really looks very much like the visualization relates to the music I'm listening too. Usually you just

There are a lot of different use-cases for SDcard/microSD. It's not useful to everyone, but I think it's definitely useful enough to have built in. Same with HDMI.. I'd probably use SDcard more than HDMI (like for settin

I think he meant "hate" is too strong of a word. My impression is it just didn't serve much of a purpose for most people. I almost never use the function keys for anything but volume control anyway, and probably wouldn't

I still think this is good for Taiwan’s security. The world is very aware of Chinas growing ambitions, and everyone views Taiwan favorably. Taiwan needs to focus on being viewed as the better partner to liberal democratic countries. I think

Do you think Apple would argue that they can’t put USB-C on a phone? Or have they already? I haven’t seen it and it wouldn’t make much sense. The only consumer oriented argument, which IMO isn’t bad, is that a lot of people have Lightning p

What I’ve seen is that a product is being designed with both ARM and RISC-V cores. The RISC-V cores outperformes the equivalent ARM cores and have no licensing costs. It’s used if it’s a management core not usually programmed by the custome

Why is 5 on each wings a stretch? With electric motors you have a lot more flexibility, and distributed propulsion has some significant benefits. Check out maxwell X-57 for research on this: https://en.m.wikipedia.org/wiki&#

Whether it is charitable or uncharitable depends on your subjective interpretation of the intent of the training material. But I think the focus on not talking about market share is a huge sign that this material is not written with good in
