This bus concept is in the spirt of ATM (Asynchronous Transfer Mode)
technology which I am very much in support of. ATM can be emensely
flexible not only in periphrial support but also in direct network and
multiprocessing support as well. SUN Micro's new highend
server is based on an ATM type bus in support of parallel processing.
I enthusiastically support this proposal as an end user and as an
embedded systems builder. I need it and I need it cheap. Cheap comes
with volume so the PC market is a great place to start.
One suggestion or recommendation would be to not exclude from the design
the hooks necessary for multiprocessing or direct interconnect between
remote systems (i.e. distributed processing or periphrial sharing). Multi-
CPU connect might be simply accomplished with dual or multiport IOC's as
follows,
CPU1 CPU2
| |
memory---| |---memory
MIOC MIOC
\ / \
IOC dev3
/ \
dev1 dev2
The network could physically be the interconnect between an IOC and dev1 or
MIOC and IOC. The only discriminant is the speed.
My 2 cents. ;-)
