Thanks I was pretty sure about the lead of the MBX. I'd like only a "official" source ;)

Hi all, i'm trying to figure out the market shares for the embedded GPUs. I'd like only a rough approximation counting the devices already on the market. Thanks Valerio

Maybe i did some mess. :???: I'm only trying to understand how the HSR is implemented in a TBDR or, better, in the PowerVR architecture. :) For what i've read is implemented on a per-pixel basis, and for what the article says, but not only that article, for each pixel the color is determined...

For doing that you only need a good algorithm for building bounding boxes to bind triangles to tiles and divide the render surface and then a simple Z-Buffering algorithm to fill the Z-buffer. That seems your solution B. But in this way I really don't see were the ray are used. :sad: I think...

Hi, I'm trying to go in depth and understand the TBDR .I'm reading this article: http://www.beyond3d.com/articles/tilebasedrendering/index1.php that's quite old, but I think that the PowerVR architecture is not changed a lot. Now i have some doubts about the HSR algorithm. That article says...

Thanks ;)

Mmmmhh. This makes really sense, cause i'm not able to find any information. So what i've read here (http://kotaku.com/gaming/n+gage/nokia-unveils-ngage-30-241566.php) ... ?? By the way... some tech. info on the Ngage 1.0 ?? :roll:

Hi, I've heard that today at the mobile GDC Nokia have talked about the NGage 3.0. So I've strated searching technical information on the Ngage 2.0, but i was not able to find anything. Could someone give me a link?? Thanks ;)

Thanks, really. But i have already send some questions... and the answers as well ;)

:embarrased: ehm... ...ok. I think i've confused the TBR and TBDR. :roll: Thanks for clarifying me that they are different, but now i have to understand what the word "deferred" implies. It means "only" that the HSR is applied before than usually and so only the visible pixelsi are...

what a wonderful list !!! Thanks ;) Yes, of course. But i'd like to know why they leave the desktop market. Or better, i'd like to know if there is a technical reason that put them out of the Desktop market. Could be the Tiled Based Rendering still a good technology fo the desktop...

Thanks for the hints :wink: So you think that the absence of PowerVR in the PC market is indipendent form their technology and depends more on their strategically choices ?? About power consumption... ..from the point where i am i'd like to find a system to track the behaviour of the...

Hi, i'm working on my final thesis and its objective is to analyse embedded GPU looking on their energy consumption. For this thesis i have the possibility to work on the PowerVR MBXLite GPU (embedded in the Freescale iMX31 SoC). It's a while that i'm surfing the net, but i can't find some...
