RSX taping out in few weeks, will we get Xenos/RSX new info?

Thats what I want to see....after seeing Xenos, i'm really anticipating what the RSX will do.
Can you guy get anything out of the RSX Patent

RSX at the end of august?

I agree but most poeple around here seem to think Sony\Nvidia did some add\remove with the GPU. Removing the PC parts that are not needed and adding other parts that would be more benificial to a console. I think it's possible, a little unlikely but hey who knows what Sony has up their sleeve since they have time on their side to tweak things and make minor changes over Microsoft. Personaly I thik Sony biggest advantage is their memory bandwidth and the CELL interface.

Great find, version. This just went up today? Looks like it was filed back in 2003, and only awarded today. But reading the abstract, my limited knowledge of graphics tech can only lead me to believe that it's something to do with outputting pixels to different parts of memory. Maybe for writing to SPE LS? I will admit right now that I couldn't even venture past the first few points (1&2) before giving up. It says something about outputting to an external device or a second-function unit (secondary shader pass?). That's all I could gleam from those two points, but I don't know enough about graphics processors to know if this is a normal function or not. Anyone given this a shot yet? It looks like it could well be RSX-related. PEACE.
EDIT: I might be mistaken, but not only do some of the diagrams have clearly labeled "eDRAM", but the diagram-explaining part of the patent seems to make repeated reference to memory modules of DRAM. Um...KK's explicitly said there's no eDRAM in RSX. Obviously RSX doesn't have to adhere to any patent, but it seems to be an integral part of each processing unit in that design.

you can keep dreaming.

Or he could keep voicing an opinion? Equally the same if someone brought up something about XENON or FLIPPER.

Xenos is a buffed up Flipper. whats wrong with that

Nothing at all. But saying Xenos is a buffed up Flipper is an opinion. What MECHANIZEDDEATH said about the RSX is his opinion...if you have something to condradict what hes saying than out with it...but to say keep dreaming is ineffective and just creates needless conflict.

Thanks for the support, BT. I'm simply inquiring, and trying to figure out if my conclusions make any sense. I don't understand enough to make sense of that patent, but I thought some of it made sense. I want to know what the patent specifically implies, and why those diagrams show eDRAM. It's a 2003 patent, so it's not exactly guaranteed to be RSX-related. I'm just curious, that's all. PEACE.BlueTsunami said:
If you skip past the claims and read the main explanation halfway through the doc, it talks about combining an image processor and graphics processor into one device. They speak of 3 different takes on parallelism (quads, polys and pixels) and pros and cons.
The actually patent was unclear to me what they were getting at though (and thus it rather fails as a patent in clearly explaining itself - like they always do). Given the repeated use of the term 'versatile' I think the invention is a device that can switch comfortably between graphics rendering and image processing. Best guess from what I read was inbulit image processing functionality for 2D processing.
Dunno. It'd be nice though as post-processing is a very important part of visuals. Could help produce some very nice non-phtorealistic renderers. Maybe.

Apart from denoting that the design phase is finished and getting ready for sample production as Andy already explained, it also refers to the actual printing/engraving or whatever of the photo-masks that will be used when etching the silicone wafers that'll be the basis of the chips themselves. These masks obscure light from reaching photosensitive materials depositied onto the wafer, thus creating areas that'll react differently when treated with the acidic etching fluid (getting eaten away, or remaining in place). Different masks create different patterns in stages (quite many, it seems), making up the transistors (and possibly resistors, capacitors) of the chip until it is all finished. Metal is also vapor-deposited onto the wafer in stages, to create the electrical connections between transistors. Or something like this anyway, it was a long time I read about this kind of stuff so I may not remember all of it correctly.Gholbine said:
Anyway, these days there's lengthy articles to study on the subject of CMOS semiconductors at wikipedia, so head over there if you want to know more.
