- Hi, all...
- A Blitter is a bitmap copying and transformation chip?
-
- Is this all that it does?
-
- Which chip is responsible for the STe's hardware scrolling?
-
-
- Most other game systems use a very fast graphics chip to take care of
- the sprites, scaling, scrolling, etc.
-
- My question is: If ATARI is interested in making this system a competitor
- in the computer entertainment market, why didn't Atari include one?
-
-
- The SNES has a CPU speed of 3.58 MHz! Everyone looked at this speed
- and laughed, but the graphics chip showed that the speed of the processor
- did not matter too much at all.
-
- The Sega Genesis is based on a 68000 CPU at the speed of 7.6 MHz.
- This system pretty much relies on the programmer for rotation, etc.
- BUT I'm pretty sure it still has a graphics chip. And I'm POSITIVE
- that the Sega CD-ROM player has an especially designed graphics chip
- for rotation.
-
- Recently, Nintendo announced to the world that it has developed a graphics
- chip that will be powerful enough for 3-D imaging.
-
-
- If the Falcon030 does NOT have a graphics chip that is responsible for
- these features, won't the video game systems pass this system by?
-
-
- Also, if the JAGUAR has a 64-bit RISC graphics chip like we all suppose
- that it will, the Falcon030 will NOT be able to run any of those games.
-
-
- I don't know. If I was Atari, I'd try to get the Falcon030 and Jaguar
- to both have the same graphics chip. This way game developers would be
- more willing to make games for these systems. And Atari would have an
- edge over systems.
-
-
-
-
- And wouldn't a graphics chip capable of helping out with all of these
- features save on memory? And programmers' time?
-
- I doubt there is any way that a FUTURE 64-bit RISC graphics chip can be
- added to the Falcon030 at another time...
