Ah, these are the specs I like to hear. So your telling me that the current AGA chipset can handle a maximum of 7megabytes per second? I wish I could get more stats like that. Anymore interesting 'specs' you'd like to share?
If the chipset is capable of 7mb/sec, and assuming someone writes a page flipper that will take full advantage of that, AND assuming that SCSI II is indeed available early next year - we should be able to EASILY get 30fps animations from a 4 bitplane/hires/interlaced/overscan animation. DCTV uses those specs and a FULL overscan/interlace pic in DCTV takes up an average of 150k. 30fps would only require the chipset to handle 4.5mb/sec.
Are there other limiting factors that I might be overlooking here? I am very excited about SCSI II and full 30fps animations and am saving my money for such a setup.
Lastly, just what is a DSP? I know it stands for Digital Signal Processor and is primarily used for sound, but what exactly does it do? And how would it be used in a video application?
