- Aikataulusta en tied{, mutta grafiikkapiirien ominaisuuksista kertoi Lewis
- Eggebrecht Toronton WOCissa. Seuraava leike on Scott Withingtonin katsauksesta
- (joka oli comp.sys.amiga.review-ryhm{ss{; sis{ll|n luotettavuutta en pysty
- arvioimaan enk{ ota siit{ vastuuta;-).

- FUTURE VLSI CHIP SETS
-
- CONSUMER AND LOW END SYSTEMS
-
- - 2 chips each with >100k transistors
- - synchronous to video clock
- - 160 - 280 pin packages
- - 32 bit DRAM or VRAM
- - 57 MHz pixel clock
- - ECS & AGA downwardly compatible. Ensuring this is one of the
- things that slows development
- - Support for 1, 2, & 4 MB floppy drives using standard technology
- - support for ALL 32 bit Motorola CPUs (including 680x0, and 880x0)
- - 8x memory bandwidth over AGA, 2x (at least) blitter performance
- - 800 x 600 72 hz resolution, higher at lower refresh rates.
- - 1 - 24 bit colour at any resolution (this was decided the week
- before WOCA, at Pasedena he said 16 bit)
- - FIFO serial port with large buffer to support very high baud rates
- - 8 meg chip RAM, all but unlimited fast RAM
-
- HIGH END SYSTEMS
-
- - 4 chips (750k - 1M transistors)
- - 32/64 bit VRAM
- - 57 - 114 Mhz pixel clock (asynchronous design)
- - chunky pixel mode (commonly used in IBM PC systems) which will be
- supported by the blitter (bit instead of word)
- - CD-ROM with 100 Mbit/sec transfer rate
- - frame buffer/grabber built in
- - screen promotion
- - 1k x 1k x 24 bit 72 hz screens (more at lower refresh)
- - 8 voice 16 bit >100Khz sound
- - on-demand DMA
- - 12 - 20 x memory bandwidth (32-64 bit memory)
- - 32 bit blitter (8x performance of AGA)
- - 24 bit true colour mode
- - will support multiple simultaneous chip sets working together,
- allowing separate displays, or drastically higher resolutions
- (multiprocessing)
- - enhanced hardware compress/decompress including JPEG/MPEG
- - video upgrade modularity
- - 100 Khz
- - 32 bit processor independent bus for new CPU's (multiprocessing)
- including RISC chips (they should announce a choice for RISC chip
- in less than 1 year)
- - asynchronous design
- - 1 downside is that it may not be 100% ECS/AGA compatible
-
-
- PS. Katsaus l|ytynee kokonaisuudessaan nic:st{, jos se joltakulta meni
- ohi silmien.
