- The product I mentioned really has nothing to do with the Amiga, I just did
- the demos loops for it with LightWave. It is a 6U VME board(s) that go into
- Concurrent real-time unix platforms. There has been talk about releasing them
- for other systems but that is a marketing issue. In any event, they are i860
- based, have a resolution of 1280 x 1024, and are avaible in 8 and 24 bit
- versions. The X11 server runs directly on the board and does VME bus mastered
- DMA to offload the host in a big way. Up to 8 of them can run on a single host
- without too much performance degredation. Besides being real X11 screamers,
- there greatest strength is image load speed. An 8bit 768 x 480 uncompressed
- image loop can easily run at approximately 50fps. I have not actually measured
- the 24bit rate yet because there is a bug in the code that is parsing and
- displaying my 24bit IFFs. The goal is to hit 30fps but we may miss that by a
- small margin...we believe there is still room for some optimization. The image
- transfers take place over the VME bus out of host/system memory and present
- nearlly no load to the host. Similarly, X performance remains very good while
- running animations. The board is called the GA5000 and I will be bringing my
- own 24bit card set to the show for the exhibition. On it will be a variety of
- my demo anims which some of you may have seen....The Toy Room, Backyard Pool,
- F15 over Kings Canyon, the morph of my wife, and a couple test runs from my
- latest animation project which features some very nice rain sequences. I
- designed the ASICs on this board but my cohort here actually did the overall
- board design. As for price, it would be best to talk to Concurrent sales and
- marketing, but suffice it to say that it is out of the average Amiga owners
- budget (in the $10K area).
-
- We will also be showing an unannounced 3D product developed with a partnership
- with Du Pont Pixel. It uses 4 i860s and is aimed at GL (SGI) applications.
- This board is the GA6400 and is one of the products I am in charge of
- developing.
