ArtX 1 AGP System Controller Driver

While Nintendo is willing to state a geometry performance number for Flipper, they do not publish peak pixel or texture fill rates.

However, one thing we have heard is that Flipper may be a larger, more powerful version of some previous ArtX graphics cores, which mostly appeared in integrated solutions. But according to ATI spokespeople interviewed, the similarities between Flipper and previous ArtX cores basically end there. These ArtX cores have been traditional triangle-based ArtX 1 AGP System Controller, but can do early Z-tests hidden surface removal to help reduce the pixel processing load that later pipeline stages will have to handle.


For information on 3D pipeline technology in general, please refer to my three-part story starting here. The 48 year-old NTSC standard calls for an analog signal capable of producing scan lines of vertical resolution i.

The visible TV screen area displays around lines. This is a fixed number. Plus signal interconnect methods composite, S-Video, component video, etc affect horizontal resolution too. Goes without saying, and you already know that a game console displaying on a TV inherently has nowhere near the resolution of high-res PC graphics. But still, these are ArtX 1 AGP System Controller meager requirements.

More on fill rate issues below.

Assuming only one pixel processed per ArtX 1 AGP System Controller, Flipper could theoretically redraw every pixel on-screen 18 times per frame. But Flipper likely has at the very least two pixel pipes in order to be competitive with PS2 and Xbox, and with two pipes it could redraw every pixel on-screen 36 times per frame.

With four pixel pipes—a more likely possibility—that number doubles yet again where each pixel on-screen could be drawn 72 times. Given the probable logic transistor count in Flipper—somewhere around 26 million transistors, with about another 25 million used for the ArtX 1 AGP System Controller of onboard memory—we believe Flipper has four pixel pipes, each with one texturing unit. Add to the complication mix multi-texturing effects, and antialiasing, and these numbers will certainly diminish.

But, what becomes apparent is that a seemingly modest part can still produce a lot of performance when running at an undemanding resolution. Here we run into a semantic snag: And because the occluded pixels are discarded earlier in the rendering process, you wind up with an effective fill rate that can be difficult to actually calculate, since it can vary depending on the type of workload being thrown at the hardware.

Depending ArtX 1 AGP System Controller the effect being rendered, shaders can add considerably to the overall workload, but also free developers to reconfigure the 3D pipeline to fit their particular needs.

Despite being demanding, ArtX 1 AGP System Controller are often less so than creating the same effect using multitexturing, which eats memory bandwidth for lunch. As to how close any platform gets to achieving its maximum geometry throughput is, of course, highly dependent upon the efficiency of the game engine and hardware, combined with fill-rate capabilities of the pipeline. In the past, 3D chip makers were somewhat notorious for quoting theoretical polygon throughput numbers that assumed a null renderer; in other words, that every pipeline stage after the geometry processing i.

This is ArtX 1 AGP System Controller a reality-challenged view of the 3D world, since geometry rate is absolutely dependent upon how fast the rest of the pipeline can go. Because of the highly serialized nature of 3D graphics pipelines, this system is only as fast as its slowest part. Plus polygon rate quotes ArtX 1 AGP System Controller always indicate the average triangle size used in the calculation. So we wondered where the front buffer the one being displayed on-screen while the next frame is being rendered to the back-buffer was located.

Then ATI partially unraveled the mystery for us: What this likely necessitates to avoid tearing artifacts is actually running triple-buffered and allocating an additional 1MB of the 24MB of MoSys system memorysince the on-chip back buffer never actually becomes the front-buffer. And this would require two buffers off-chip. Check out this diagram to better visualize this: What we found from ATI is that the buffer configuration is basically up to the developer, so a game could run triple-buffered, quad-buffered, quint-buffered, etc.

The number of off-chip color buffers would depend on how many frames ahead a game engine was trying to ArtX 1 AGP System Controller. And while this may be possible, we still believe that GameCube uses the triple-buffering scheme at a minimum, as described above. By using integrated SRAM for its frame buffer back buffer actuallyGameCube is able to achieve a higher peak data rate, although ATI did tell us that the memory interface has a respectable bit width, and they hinted that it could be thought of as two bit interfaces.


ArtX 1 AGP System Controller It may also be that Nintendo opted for this clock rate to help keep build of materials costs down, or for better reliability and a cooler-running part with less thermal requirements. As previously reported by EE Times in May of this year [click here [3]], Flipper has 51 million transistors, and about half of those are the 3MB of integrated memory. And doing a few more back of the envelope calculations, we determined that the 1MB of texture cache likely has four such channels, since the 2.

Now 1MB may seem like a paltry amount of texture cache, but Flipper can use S3TC texture compression, with a compression ratio of 6: However, ATI was willing to state that the color and z buffer memories each had their own discrete bandwidth, so if each were allotted a single channel, this would provide 2. Low-latency increases effective bandwidth, since you begin moving actual data ArtX 1 AGP System Controller after the request for it is made, so in a given time-slice this nets an increase in the amount of data you can transfer.


This data rate is admittedly about half of the 7. And if a game needs a piece of data fast and the only place it can be found is on the CD-ROM, then the game is up a certain creek without a paddle.
