PlayStation 4 (codename Orbis) technical hardware investigation (news and rumours)

Ask about the memory usage ? Oh people will ask. It depends on what Sony want to reveal.

We should hear more when they talk about PSEye, and perhaps app development -- assuming they want something to counter iOS/Android app development.
 
We have already seen interviews with PS3 and Vita audio engineers about their respective audio libraries. I posted them in that audio thread. If Sony continue this tradition, we should get one for PS4 too.
 
Only if they are confident it stacks up well to SHAPE. CELL provided excellent audio and im pretty sure vita cannot be touched technically in any regard by other handheld hardware currently available. So its good to talk about that. Talking about something that a direct competitor kicks your arse with probably isn't a wsie thing to do
 
You probably mean PSP instead of PS3? Because PS3 has just a straight-pipe codec, all audio processing runs on the cell processor.

That's why I mentioned "DSP-like" audio processing. ^_^ The SPUs shoulder these responsibilities like a lone DSP would. It would be a waste if they include a DSP for audio there. In the interview, the Sony dude made a distinction between game audio vs regular audio. The former has more sophisticated requirements and processing needs.

That's true, but they can talk about the overall audio approach. The audio processor in PS4 should be pretty efficient and powerful too. Cerny also mentioned audio raytracing using the GPU. It's all about how you position yourself. e.g., The Vita guy made a case for his Vita stack against the SPUs in the Vita audio interview.

Personally, I am just curious how different pieces fit together.

If this patent is for the PS4 I think we will be hearing about the Audio Processor.

Automatic computation streaming partition for voice recognition on multiple processors with limited memory

http://patft.uspto.gov/netacgi/nph-...-comp$+and+audio&RS=(AN/sony-comp$+AND+audio)

Through appropriate configuration of the foregoing components, the main processor 301 and co-processors 302A, 302B may be configured to implement the speech processing operations described above with respect to FIG. 1 and FIG. 2. Specifically, the main memory thread(s) 305 may perform memory maintenance and voice recognition result retrievals. The main memory thread(s) may trigger the application 304 to change a state of the apparatus 300 when a word is recognized. As used herein, a "change of state" refers to a change in the operation of the apparatus. By way of example, a change of state may include execution of a command or selection of particular data for use by another process handled by the application 304. A non-limiting example of execution of a command would be for the apparatus to begin the process of selecting a song upon recognition of the word "select". A non-limiting example of selection of data for use by another process would be for the process to select a particular song for play when the input phoneme set matches the title of the song.
 
Touch screen-like user interface that does not require actual touching

http://patft.uspto.gov/netacgi/nph-...comp$.ASNM.&OS=an/sony-comp$&RS=AN/sony-comp$

Touch screens have proven to be very good for casual user interactions with computers, but they have the disadvantage that the screen quickly gets fingerprinted and dirty, which is not something a user wants to happen to the living room big-screen TV.

Embodiments of the present invention allow a person to use his or her finger as a mouse-like pointing device to manipulate a touch screen-like user interface, but without actually touching the screen of the device. By way of example, such embodiments may be implemented in an inexpensive system that allows a big-screen TV to be used as an interface to a home server or the internet without the need for a remote control. This allows the TV to be easily used for casual walk-up interactions such as home control, brief web browsing sessions, checking traffic, weather, etc., where the use of voice control or a remote or hand-held pointing device would be inconvenient. Furthermore, the screen would not get dirty because the user does not have to touch it.
 
@Xenio

Maybe I wasn't clear enough.
A 3GB OS doesn't make sense with PS4 initial 4GB memory setup (the 512mb suggest by DF make sense) and it's very unlikely that the memory reserved for the OS increased after the PS4 "upgrade".

First, let me start off by saying that I'm not saying any of the following is going to be how things are. People love to jump to conclusions here when defending or attacking the other consoles (like the Durango speculation thread).

Anyway, if we assume that the Chinese guy is a developer and he's correct. Then there is nothing strange or unlikely about it.

KZ:SF used ~3 GB of memory which some think include stuff that won't be included in the game accessible memory on final hardware. Hence, a 5 GB partition for games represents anywhere from a 66% - 100% increase in available memory to games. A still massive increase compared to what they were working with before.

If the 8 GB added was a response to Durango basically being all but confirmed as having 8 GB of memory, then why would it be so strange to think that Sony would also wish to remain competitive when it comes to living room services, apps, OS features, and potential game enhancing features (more robust motion tracking and voice recognition, for example). So, while 3 GB is perhaps a bit excessive considering Sony isn't going to be doing skeletal tracking at the level that Kinect is anytime soon (presumably), it's also not out of the question.

With 4 GB of total memory it makes a lot of sense to use as little as possible for the OS in order to make the games look as good as possible. With 8 GB of total memory, it would make a whole lot more sense to reserve enough for the system and OS to make sure that they are not at a competitive disadvantage versus the competition. Especially when you consider that the vast majority of games developed for your system will be multiplatform and unlikely to make use of more memory than the competition.

Again, not saying the 5 GB partition for games is necessarily true. Just speculating on why it might be done. IMO, a 5/3 or 6/2 split for memory makes the most sense as that allows them to be competitive with Durango on almost all fronts, not only at launch but 2-3 years from now as MS adds more services and if Sony wishes to add more services. Services which could potentially benefit games. Remember, both systems have the ability to overlay a UI display plane over a running game. Whose to say that either Sony, MS, or both won't come up with novel ways for that to include information about the game or that is beneficial to the game or that enhances the game with stuff that is universally accessible to all games.

I'm sure Sony doesn't want to be in another situation like they were with PS3 where they didn't have a key feature such as universal, standardized voice chat due to not being able to reserve enough system resources for it. I'm going to assume PS4 will have that. But, who knows what the next key "universal" feature might be.

SB
 
Theres a chinese guy on GAF saying another guy on chinese BBS is saying PS4 has 5GB of RAM available for games.

I'd dismiss it but apparently (the BBS guy) a dev, who also mentioned two cores reserved for OS a month before the Shadofwall presentation

Relevant post links in order

Digging a little deeper and running some of the Chinese guy's (alleged dev) posts through Chrome translate (really handy how it offers to auto translate foreign pages, I use Firefox but love that feature of Chrome) I get:



The news he's talking about is it's a thread saying PS4 has 8GB.

Then this exchange





Couple posts later



And



There's where he mentions the 6/2 core split. That post is dated 4-13-2013.

Allegedly he works for a "Ratloop studio"

Which googling has this wiki page

http://en.wikipedia.org/wiki/Ratloop

Guess that guy would work for the Singapore branch. Anyways enough Sherlock Holmes for me.
How a guy(dev maybe) that works for a little studio like could presumably getting more informations on the final specs,or simply such informations about the amount of ram reserved for the OS before any devs that work for any major studio,and being credible, dear Watson?
I really doubt SONY sent any(even early) dev kit to a studio like Ratloop who developed only flashgames and IOS games ,before being sure that EA/Activision/UBIsoft or any other major Editor/dev studio get their own.My guess is that those little studios are the last being served ....
Sorry for being so sceptical about this...

what make you think that ea don't have the dev kit??
 
I'm not sure how much RAM iOS, Android use without any apps running, but I think it's somewhere in the range of 250 - 750 MB. Not totally sure of that. 512 MB seems really small for a console OS that's supposed to have pervasive services like stream broadcasting, video chat, voice chat, eye-toy voice control etc etc etc. Somewhere in the 1 - 2 GB range sounds more plausible, like what you'd have on a phone or tablet.

It’s probably because he claimed he’s been using the (8GB) devkit for a few months now. But the 8GB news was a surprise to most outside devs until the Feb presentation. The 8GB devkit probably shipped after that.

He hasn’t replied when someone asked him how he got an 8GB devkit.

Free RAM is wasted RAM. Like any modern operating system Android will make use of any spare RAM, but Android 4.x and iOS 6.1 work adequately on platforms with only 256MB of RAM.
 
It'd be a bit of a let down for developers, a lock to 5GBs. After their enthusiasm after the reveal, "wow, so much RAM!" and presumably working with 3.5 gigs before then, this whole, massive splash-out on expensive RAM nets them another 1.5 GBs only?

GG probably had the inside track on this knowledge. And it's not necessarily they were planning on their engine to take up 5.5 GB of RAM on the PS4 is it? Maybe they were on the trajectory to being under 4 GB before also (until they found out about the change) or that the 5.5 GB is more appropriated to the PC devkits than anything else.

Either way, for most developers the extra 2 or 3 GB of RAM still applies I would guess, and I imagine they are still much happier than having 4 GB for the whole system.

I think they are still thinking they moved from essentially 3.5 GB to essentially 6 or 7 GB.

I'd pin it somewhere around 512MB to 1GB.
They managed to do quite a bit on PS3 and 360 with much, much less. Giving it over 1GB seems like total overkill. However I won't be surprised if they reserve something around 2 GB at the beginning of the life cycle and along the way lower it down to 512MB. Anything over 2GB is, well, bloated in my opinion.

Also points to the relative ineffectiveness of WiiU which, come to think of it again, has 1GB (!) reserved and runs stuff like my mother's 6 year old laptop.

My Iphone 5 uses around 250MB after a reboot without any apps running (about 50 processes active)

Dev kits always had 8GB, the surprise was that the retail unit would have 8GB.
 
Yes, I meant the devkit for the 8GB retail unit. How much memory does the latest devkit have ?

In the earlier devkit(s), GG mentioned that they could only use 3.5GB for games.

Hopefully, we hear more info from multiple sources like last time.
