Subject: | SCSI on AmigaOne etc |
hi,
http://groups.yahoo.com/group/amigaone/message/4379
contains an email (almost internal) from Amiga.
now, theres some really good info within the text
..i'm looking at this sort of thing
" It can do more than just read and write the SCSI bus
- as it has bidirectional DMA you can use it as a
general-purpose block transfer device to take the
load off the CPU when moving data around main memory
or between motherboard RAM and video RAM, let's say.
It can even do horizontal and vertical scrolling and
window operations, though you'd probably want do this
using the video card local CPU and bus in practice :-)
"
wow, just like the Amiga custom chips.....so imagine this, yes, bung one
of these in as a SCSI controller....but why not also bung in an extra one
(very little cost) onto the PCI BUS as a fancy controller chip for use by
programmers as a CPU-loadless data transfer system for shifting large
amounts of data around (I'm thinking virtualmemory pages, game-data, AI
tables, cell-data etc etc)
any thoughts?
