    Pandora About Floating Point On The Pandora

    I can tell you my experience from iPhone 3gs which is using the same CPU. Essentially, I am using a lot of handwritten asm VFP/NEON code to handle various transformation + C versions of the same code. The compiler on 3gs is actually generating NEON code ( not very optimal and not vectorized but...

    Pandora Not Powerful Enough?

    PPS is mostly meaningless for 2d style rendering which depends mostly on fillrate ... to give you an idea ... I was able to pump about 2500 alpha-blended 32x32 sprites on iPhone 3gs ( which is slightly more powerful than pandora as it contains SGX535) while running at ~30 fps. The performance...

    Texture Compression

    On an unrelated note, I am wondering how are you handling the fact that Android is Java based while other devices (like iPhone or Pandora) are C/C++ based ?

    Texture Compression

    Given that 80% of all portable devices (phones etc) contains Imagination Technologies's hardware (MBX,SGX), I would go with: 1. PVRTC for everything that looks decent after compression 2. R8G8B8A8/RGB565 for stuff that cannot handle compression well. 3. I8/A8 for special stuff like font...

    Neon-ized Math.h Like Library

    There are a few open source 3d/2d engines/libraries available for the iPhone (oolong, cocos2d) ... with the current licence I don't think it would be possible to use your code in these engines simply because there is no way to deploy dynamic libraries on the iPhone and everything has to be...

    Floating Point Optimization Tutorial

    Yeah, it is GCC 4.2 PS. Actually, it tends to generate Neon instructions mixed with VFP ones.

    Floating Point Optimization Tutorial

    It does on the latest iPhone ... as long as you are using floats and not doubles.

    Always Innovating Touch Book Specs And Release Date Announced

    A curious statement given that both KDE and Gnome (and their respective apps) tend to borrow extensively from both Windows and Mac GUI designs/ideas.

    New Iphone 3g S Has Same Hardware As Pandora

    Depends ... in terms of GPU power , the iPhone should be slightly faster but beyond that who knows ....

    New Iphone 3g S Has Same Hardware As Pandora

    I don't blame you ... it is kind of hard to compare performance against a device that doesn't exist.

    New Iphone 3g S Has Same Hardware As Pandora

    I have no idea who Exophase is but I tend to trust my own device more …. which happened to have a file named IMGSGX535GLDriver.bundle not to mention GL_RENDERER reporting SGX 535. http://www.glbenchmark.com/phonedetails.jsp?D=Apple%20iPhone%203G%20S&benchmark=glpro (GL Environment tab)

    New Iphone 3g S Has Same Hardware As Pandora

    iPhone 3GS has SGX 535 as opposed to Pandora's 530 ... couple that with the fact that it needs to "power" 480x320 pixels as opposed to 800x600 and it is clear which platform will perform better.

    I Guess We Won't Be Seeing Any More Quake On Pandora

    No, they can't do that because, unlike in Germany (http://en.wikipedia.org/wiki/Volksverhetzung), the US actually does quarantee the right to freedom of speech.That's why if you are a Nazi sympathizer or white supremacists of some sort , your only option is to have your site hosted in the US...

    Pandora Buying A Beagleboard While Waiting For Pandora

    And the good thing is: I'm going to buy one to replace my iphone first generation (I don't like to call it 2G, but well..) The bad thing: it runs macosx, not linux, so apps have to be adapted to objetive-C (you can mix objective-C with C/C++, but you can't compile a C/C++ only app for the...

    Pandora Buying A Beagleboard While Waiting For Pandora

    Well there is another option ... the latest iPhone 3GS with Imagination Technologies SGX GPU ( the same as in Pandora) - it supports OpenGL ES 2.0 and 1.x etc ..

    European Elections

    This is a nondescript word ... it literally means nothing , for all you know a progressive party could be quickly progressing in the direction of hell …in which case I would rather stay conservative.

    Pandora Has Compettion

    I makes no difference ... a console like Pandora will sell perhaps 4-5 K units altogether ... there is a good chance Sony sends out more units per quarter just to replace broken ones still under warranty.

    Pandora Sdl 1.3, Glu And Nehe Opengl Tutorials For The Pandora

    Not much help in terms of emulating ( although sometimes it can be helpful) but for regular 2d games there is simply no comparison ... and don't forget about all of this being done on the GPU which means you get it all almost for free... which in turn means you can dedicate your CPU time to all...

    Pandora Sdl 1.3, Glu And Nehe Opengl Tutorials For The Pandora

    Sure you do, a TBDR works just as fine with or without a zbuffer. The only difference is that with the zbuffer present , you don't have to worry about back-to-front sorting of your geometry. If you submit your geometry in the correct order, even without the zbuffer present, it will still cull...
