    NEON scalers

    not if you "misalign" the palette to start at +14. at least for SNES, you'd only get 1 in 16 entries in most cases since entry 16, 32, ..., is rarely used. but then you waste a whole cache line just to contain entry #0 and that one could be used A LOT. and that's a lot of work just to pack...

    NEON scalers

    I haven't checked the code yet, might be fun to do a pass on it. there's a trick I used a long time ago on GBA, you can actually read 16bit values as unaligned 32bit values: ldr value, [palette, pixel, lsl #1] its "wrong" but it works, I tried it out on Pandora, it still works...

    the open pandora 2 must use an amd apu!

    PVR tile memory is just a single tiny tile per core (32x32 iirc). it gets flushed to RAM and reused as the frame buffer is rendered tile-by-tile. the whole point of tile based rendering is that you only need 1 tile on die. afaik none of the tile-based-rendering GPUs hold more than one tile...

    the open pandora 2 must use an amd apu!

    they're both targets and sources. realtime shadow map has to be rendered, then written to RAM, then re-read from RAM as a texture bloom has to be rendered, then written to RAM, then re-read from RAM as a texture and normal maps have to be read from RAM then processed in a shader (memory...

    the open pandora 2 must use an amd apu!

    to get back on the CPU topic, my 2 cents: I don't care as long as we have a much better GPU. the current GPU is too weak. right now it would need to be at least 4x as fast with the current pandora's resolution to be called "decent". what the VITA has is "acceptable" (as long as you don't...

    the open pandora 2 must use an amd apu!

    probably true. power stations can hit 95% efficiency, electric engines are generally around 90% efficient, most of the loss will be in the wires to get to your house and battery charger. in comparison gasoline engines in cars are barely 35% energy efficient, diesels 45%, gasoline hybrids are...

    The N64 situation

    really, I would not be surprised if heavily optimized software rendering on the ARM Cortex-A8 at 1250 Mhz (in N64 native resolution of 320x240 or 256 × 224) wouldn't be faster than using the SGX 530 GPU for N64 rendering. the N64's GPU is so different from the SGX, properly pipelined ARM code...

    The N64 situation

    the N64 uses almost exclusively 4bpp palettized textures, which the SGX does not support directly. the N64 "GPU" is a 62.5Mhz fixed-ish graphic pipeline, the SGX is at 110/200Mhz using programmable pixel shaders (bigger overhead). N64 games like the Zeldas used a lot of alpha blending and...

    scale2x / scale3x shaders

    dependent computed texture coordinate accesses (ones with code before them) are slower than conditional on SGX using textures as lookup tables is really slow. the source image is regenerated every frame, so would the precompute lookup, that would eliminate any and all savings in using the...

    you're missing the point. what about the game engine and tools I've spent years and lots of money working on? you're selling commercial game clones on Android and other markets, why in the world would I give the source to my games and tools to one of my competitors? you are confused, your...

    Using Pandora as phone replacement?

    I got a cheap Chinese 7" MID Android tablet with SIM card slot that can make phone calls. I like to use it for the comedic effect. its like using a iPhone if you'd be 2 feet tall. I got a data SIM card in there (no voice minutes included) but its totally worth the extra charge incurred to...

    Ouya - Android based open gaming console

    the plastic case is legally "hardware". they can claim that's all they meant. at least that's the feeling I got from the video. maybe they got solder points for extra LEDs or other ports. the whole sales pitch was carefully crafted to sound more open than it most likely is. with a lot...

    Ouya - Android based open gaming console

    deserved to a certain degree, yes. for sure, the old orders must absolutely be fulfilled before doing a KS it'd be suicidal otherwise. well, OPT publicly raised some skepticism against OUYA: http://www.pocketgam...ure.asp?c=43030 it'd be only fair of them to return the favor.
