    So I assume that the Vita isn't using all of it's resources towards games (and home) to ensure that it can run this in the background?

    With a quad-core CPU it can afford to multitask quite efficiently. ;)

    By the way, background processes do not mean that the system restricts resources in applications - all it means is that the system is capable of multitasking via whatever means.

    I would assume the system does restrict resources. It would have to in a case like this of running more than one application at a time. Unlike a computer, the Vita does not have anything to fall back on should resource usage reach its limit. Take RAM for instance. When a computer is unable to hold all of its active (and inactive) programs in RAM, it relies on virtual memory for management. The Vita has no setup like that, and the only logical approach for this I can think of would be to do something like the 3DS does. Allocate enough RAM for just the OS and other background programs as one section, and games take the rest. How much for the OS? I don't know, but enough for its needs. If Skype doesn't take from the OS allocation, then it is taking from the game allocation, to which complications could arise. If it is taking from neither, then there is a separate allocation section of memory tied directly to such programs, not used by the OS or games, so limits are placed on each.

    As far as the CPU is concerned, while technically it'll handle multi-tasking just fine, it'll have the same problem that computers do when the load is too much. Slowdown. I would assume they went with their PS3 approach, and have one SPE (or in the Vita's case, a core) specifically for the OS and such programs like Skype so that they won't interfere with the games.

    Restrictions of resources.

    Obviously the area of memory used by the system is not accessible via User Mode, but that doesn't necessarily mean that the amount of memory dedicated for background applications has to be *fixed*, the OS may simply request allocation of memory and said amount of space in RAM will be allocated for it, similarily to how the PS3 handles it - memory allocation between levels can fluctuate. As for the amount of calculations background processes require, this also does not have to be fixed or dedicated to any specific core.

    We don't really know how the OS of the Vita works as of today but my guess is similar to yours - that they went for the easy way of handling things and dedicated a single core for the OS simply because the Vita does *a lot of stuff* in the background as it is.

    The way I see it, one core is dedicated for the OS, no matter how intensively it is used, RAM is allocated dynamically and the remaining three cores work in a Performance on Demand scheme to prevent draining the battery even quicker than it already drains. Sounds about right?

    I made mention of the RAM allocation because of possible conflicts if both OS and games dynamically adjusted their usage from the total, as both could possibly require a lot at the same time, that when combined would be more than the Vita has, and a war would start. The 3DS has 32MB of the 128MB allocated for the OS and all its minor apps, with the remaining 96MB for just games. That is my assumption for the Vita as well in terms of allocation.
     
  6. If Skype could run on the PSP (2000+) with 64MB and a worse CPU, I'm pretty sure it can run on the 3DS. Just saying.

    And yes, I know it probably wouldn't be as good as the Vita version, but w/e.

    we've learnt from the ps3 that sony does not allocate 'just enough' ram for the os
    Re-read my post. I'm not saying it can't run.

    I could see Skype actively running in the background of the 3DS, but that isn't without potential problems with how the 3DS currently does things. On-screen notifications aren't a concern, as I feel that can be done with an OS update if it can't do something like that already (nothing says the displays are locked to the games while they are active even though that is all we see). The question is how it would be integrated with the OS, as it would have to deal with needing cycles from the 2nd CPU/core, allocation from the 32MB of OS RAM, and whether it would conflict with the current OS mini apps.

    But you know, this is a thread for the Vita, so perhaps we should move back into that discussion.

    thats the whole point with sony in contrast to nintendo.

    sony seems to be joining many normally known and used features much earlier than nintendo. nintendo took their time with facebook. it should have been a launch app or something.

    with this, it seems sony is not going for partnership with the big guns. a very safe strategy.

    Trying it out now. I'm glad I don't have to worry about chatting with people on the computer, while playing the Vita. ^-^

    Few quirks.

    Can't use Sony Microphone. (Basically you're muted unless you use the built in mic.)
    Incoming video is a bit choppy, but good. (My friend said that the broadcasting video was great.)

    That's about it.

    Well, hey, that's a nice add on. Not really essential, but I'm not going to start complaining about it either.

    People who complain about free stuff are dumb. This doesn't affect anyone negatively that don't use it, but is positive to those that do.

    Wasn't Skype originally free on the PSP anyway?

    This would be great if I had a Vita

    There's a built in mic on the system?

    Well, I never knew.

    Mostly I use Skype for text chats and the occasional voice chat but I'll probably just stick to the computer for that. Maybe I'll use it when I'm at a job since "a job" usually means me sitting alone in a small room for a couple of hours, aiming cameras at boring board representatives as they blab on about how we're blowing our school budget on iPads.

    BUT I DIGRESS.

    ^Yes it does. It's what allows you to talk in Parties, and use the application in Welcome Park.

    Praising a product does not mean that I am discussing tastes. Please respect my opinions, that you began to discussion, I'm burying it here.

    There is a huge difference between praising one product and bashing another. You will not succeed in convincing me that your comment about the Vita had no negative connotation dear Pablo3DS, the moment you cross this line, whatever you say is no longer an opinion that deserves respect. If you choose to use an actually useful yet optional feature to undermine the position of a product you clearly dislike, you are being a fanboy. Your nick alone is a testament of your objectivity, don't you complain when people poke at your hardly clever remarks when you bring nothing but poison into the discussion.

    I don't even mean to be rude now, not at all, but don't hide behind the cover of personal opinion because it is not bulletproof.

    My God what drama you're doing because of my name, since I said I do not like PSVita?? I put Pablo3DS because I have one, and always enjoyed giving Nintendo more than Sony, what I said was not poison, it was praise, I was happy that the technology isadvancing. Now, do a favor? Get that pigeon poop out of your head, okay ?
