ARM continues the legacy of MIPS. Development on the MIPS instruction set ceased well before the PSP was out, you can get MIPS based processors for embedded systems still though.

PlayStation 1 CPU powers #PlutoFlyBy / NewHorizon probe
- Thread starter Man
- Start date
The R3000 is actually a more general purpose processor was used in many, many other devices like servers and workstations and It was not designed for ps1. It was already over six years old when the console was introduced. Also the cpu in the probe is not the original cpu but a heavily modified one.
I'm new be nice

How can it accurately navigate without a Z-buffer?

PS5 has to be called PlayStation Pluto now. PSP.
You should totally work for NASA bro.

Yeah, science gadgets are ridiculously overpriced.

Yeah, SpaceGAF would just put some Raspery Pi platines together and call it a day.
Just send a second satellite if the first one breaks!
I'm actually looking into getting a PS1 dev environment up and running on a hobby basis.
One option is to buy a Net Yaroze of EBay but it doesn't have the full feature set of an official dev kit (some hardware debugging features missing etc).
Other option seems to be getting the official SDK tools somehow and run my code in emulators like ePSXe.

Very low production volumes. If the PlayStation MIPS was not mass produced it would cost very similarly albeit without the extra process and binning that goes into making a CPU for space use which makes it even more expensive.
That's not a completely stupid idea!

It is if it means to lose 7 years of time so saving 40k on a subsystem isn't worth the risk.
Did you know that Nikola Tesla helped in creating New Horizon?

"...and conquer worlds"
Looks like the advert came true after all
When you think about it, aren't we all just PSX CPUs traveling through space in search of our true purpose?
Opinions are like assholes.
It's batshit crazy to even suggest what NASA should use. Who are you again?
It navigates by using the stars, like old sailors did centuries ago.

It's not like that but prices for professional uses are extraordinary high and they can't be compared to normal consumer products.
For instance, I ordered carbon filaments for a scientific setup and it costed about 2000. Carbon filaments for modern 3d printers or other consumerist products cost in the range of 30.
Wasn't that why the PSX was quick and easy to emulate?

Posted by playstation on twitter:
Any other CPU that have a Z-buffer would become self aware under its long and dangerous journey and would eventually malfunction because of performance anxiety and stress.
The PSX CPU's blatant disregard of the Z-plane is the reason it can courageously travel all these years with no fear or remorse.

I'm willing to bet that a multi-billion dollar agency that has launched multiple spacecraft across our solar system knows more about this stuff than you do.

Well, you certainly don't, but then don't act surprised when half the internet laughs at you.

Durability is far from my mind when I think Playstation, but whatever works for them.

This is still amusing, regardless of how modified it might be or its actual cost. For something traveling 3 billion miles in 9 years on a history-writing multi-billion dollar mission that lets the US cheese a claim to every planet in the solar system, a $20-40,000 processor sounds like a bargain!
There's a massively lame advertising opportunity in here somewhere. Someone think it up and tell Sony to not use it, please.
Gonna need something a liittle more industrial than that. Temperature in space is a weird thing.

Nothing could stop you of using the cheap carbon filaments of commercial applications if the material properties are good enough for what you are trying to do with it.
Why did it stopped working in the first place?

No it'd be too hard to program for and the framerate would suck. Unless Naughty Dog built it.

They should've checked eBay. Way cheaper.
Some early PlayStation models had a faulty disc drive. The laser wasn't seated correctly, or something along those lines.
Nothing to do with the CPU, that's for sure.

You flipped it upside down when it refused to read disks. Ha, it definitely wasn't CPU related.

It actually had plastic seating the laser assembly sat in. So the friction wore the plastic down which caused the laser unit drop and lose its intensity to read. So turning it upside down brought the laser back to its normal position.
It was corrected with poly/nylon pieces that hold up well against friction.
Well they did do a visit to SpaceX...
Exactly. We should applaud MIPS for this, not Sony or the PSX. MIPS powered the PSX, the PSP, the PS2 and the N64.

I loved fiddling around with IRIX which featured scalable vector icons before Windows 95 launched.

Savage Starlight research. The probe is actually submitting data directly to ND for the development of the game.

MIPS had its latest ISA release (Release 6) just last year. Imagination now owns MIPS.

My bet is on the NASA engineers knowing more than you in this aspect.
