Modern cores can have more sram for branch prediction than they do for L1I$.

by monocasa 1y ago
To be fair, on the x86 side those branch prediction hint prefixes have been functionally ignored by pretty much all cores for about two decades.

I mean, original Dartmouth BASIC only had if and goto, and was definitely designed as a human readable language.

How far did you get, and what do you mean "regardless of cost"? The big issue is going to be getting the vehicle to pass FMVSS, and it looks like no one has successfully done it. Have you talked to an RI to see if they know why?

Unfortunately Rivian somehow has even worse reliability than Tesla. And you can buy a BYD in America. There's just a pre-Trump 100% tariff on Chinese EVs with bipartisan support that isn't going away any time soon.

I'm not saying it doesn't work; I'm asking what special sauce they've added to make it work, and noting that despite the replies I've gotten, foveated streaming doesn't help latency, and in fact makes the effec

Enough bandwidth to absolve any latency issues over a wireless connection is not really a thing for a low latency use case like foveated rendering. What do you do when another device on the main wifi network decides to eat 50ms of time in t

It's not exactly what I'd call a rounding error, but it's manageable. But yeah, tube computing in general is an exercise in building a really fancy space heater. I'm trying to keep my tube computer I'm building dow

Foveated rendering very clearly works well with a dedicated connection, wiht predictable latency. My question was more about the latency spikes inherent in a ISM general use band combined with foveated rendering, which would make the effec

The thing is that I'd expect foveated rendering to increase latency issues, not help them like it does for bandwidth concerns. During a lag spike you're now looking at an extremely down sampled image instead of what in non foveat

Yeah, nesting JITs was kind of always an Achilles heel of this kind of architecture. IIRC, they had a research project to look at shipping a custom JVM that compiled straight to their internal ISA to skip the impedance mismatch between two

More of an issue when your phone's wifi or your partner watching a show while you game is eating into that one channel in bursts, particularly since the dedicated fob means that it's essentially another network conflicting with th

Even 5.8Ghz is getting congested. There's a dedicated router in this case (a USB fob), but you still have to share spectrum with the other devices. And at the 160Mhz symbol rate mode on WiFi6, you only have one channel in the 5.8GHz

Foveated streaming is wild to me. Saccades are commonly as low as 20-30ms when reading text, so guaranteeing that latency over 2.4Ghz seems Sisyphean. I wonder if they have an ML model doing partial upscaling until the eyetracking state is

A lot of devices that you commonly plug and unplug like flash drives and passkeys still make sense as USB-A for a lot of people because of the specifics of the USB spec. C to A converters for devices are technically verboten since they woul

I mean, if you're a storage business, hopefully you've designed your architecture such that you assume drives will go bad, so you characterize the models of drive to make sure that not all the copies are on one manufacturer, and t

There's levels of microcode. It's not too uncommon for each pipeline stage or so to have their own uop formats as each stage computes what it was designed to and culls what later stages don't need. Because of this it's n

It was straight up co-sponsored by very nearly a majority of Senate Republicans (18 out of 42 at the time). It's hard to say a "vast majority of R's didn't support it". Though recently Republicans have been trying

The 1993 HEART Act was very much like the ACA, built around the individual mandate to purchase private health insurance, primarily through your employer. Romneycare was massaged out of this. https://en.wikipedia.org/wiki&#x

You don't have to mandate anything of landlords. Public housing is a thing. There are very successful examples. And on the car side, there's plenty of very cheap new options. I can literally lease a new EV for ~$100/month.
