I agree with the statement. An API is what you use to control a hardware peripheral like current generation graphics adapters. The CPU is still the 'host' controller the peripheral. However, I believe the graphics adapter, as a standalone piece of hardware you control through an API is going...

I would guess the big difference here is that with vec4 + 1 you could have just two register files, a wide vector and a scalar. Each register file would require 3 reads at most when all ALUs are set to MADD operation. In the case of the superscalar design each of the 5 ALUs can address...

The only possibility I can see for reconfigurable processors in mainstream graphics is to not use an FPGA but a course grain architecture that looks more like a grid of floating point / ALU computing nodes and a programmable routing fabric similar to an FPGA. The routing fabric would be...

If you are student, applying a student volunteer is one cheap way of attending SIGGRAPH. You basically apply to do 15 or 25 hours of work at the conference and they will give you a full conference pass to attend whatever you like (when you are not working of course). If you sign up for 25...

Does anyone know if interpolation is currently done at FP32 precision? Perhaps it would be inefficient to put these onto FP32 ALUs if this is not the case. What could you do with programmable interpolators? (RE: putting them in the shader)

After hearing the announcements about IPTV and the availability of movies and tv episodes in the US I am pretty excited about when these things are going to be available in Canada. I think Zune is expected to make it here sometime in the spring so I am thinking MS might launch tv shows and...

I do not understand why current xbox 360 owners would feel ripped off in any way. By the time I actually care about HDMI (or anyone else) it will probably be at least a year (probably 2). By that time I imagine that between xbox360 system, controllers, wifi, video cam, live, creators club...

I was downtown Toronto today and stopped in at best buy and futureshop. Best buy had a huge line and people were saying 70 units for that store. Futureshop had about 6-10 people waiting outside and they wouldn't find out how many actual units were available until store closing. This was at...

I could see this being the case for low end type stuff. Maybe even heterogeneous multiprocessiing where one of the cores has an ISA extension for triangle rasterization interpolation, and texture sampling. D3D driver almost written as a software rasterizer but exploiting the ISA extensions to...

Are the G80 scalar interpolator and special function ALUs the ones described in this paper: "A High-Performance Area-Efficient Multifunction Interpolator" http://portal.acm.org/citation.cfm?id=1078021.1078076 I know this paper was brought up at some point on this board, but was it...

Where do they buy chips, capacitors etc? From a supplier? ;) As for where they send the PCB design. As far as I know, the reference PCB design is made by the IHV and is actually built on their own manufacturing machines. I am *pretty* sure it is done this way. This would allow for quick...

Yonge and Highway 7, thats in Markham, ON, very close to ATI HQ.

I haven't read the patent, but from this description it seems to be just some power saving feature by auto adjusting the brightness control based on what is on screen. Isn't brightside tech much more elaborate than this? "The input may be computed based on a generated source image and a...

Meh, I realize that RSX is not the bottleneck to production and it is actually the laser diodes. Why are the clocks going down, just to decrease cost? Is there any other reason for it?

Not really. In fact some of the points should counteract others. For example, downclocking the RSX and DDR should increase yield and therefore HELP to keep the number of launch units at 2M (or make system cost cheaper). Negative decisions should impact other points positively (thats why they...
