PCI 9030 SMARTarget I/O
Accelerator
Only the PCI 9030 has SMARTarget tech-
nology, a set of advanced features which
go far beyond the minimum to provide
the best possible performance and flexi-
bility to simplify the design. A basic target
design is one thing, but a SMARTarget
design is much more.

Target Programmable Burst. The PCI
9030 may be programmed for several
burst lengths, including unlimited burst.
This allows for maximum transfer rates
on both the PCI and local bus.
Target Delayed Write. The PCI 9030
supports PCI Target Delayed Write mode
where the PCI Target Write data is post-
poned in the PCI Target Write FIFO to
allow uninterrupted burst transactions

Memory Writes. A PCI memory
write can be posted to the PCI 9030 for
later transfer to the Local bus. This
allows for maximum PCI performance
and avoids potential deadlock situations.

Target Read Ahead Mode. The
PCI 9030 will prefetch a programmable
amount of data from the local bus.
The prefetched data can then be burst
transferred on the PCI bus from the PCI
9030 internal PCI Target Read FIFO. The
prefetch size can be programmed to
match the PCI master burst length or can
be used as PCI Target Read Ahead mode
data. This feature allows for increased
bandwidth and reduced read latency.

throughput for conditions in which the
PCI clock frequency is slower than the
Local clock frequency or when Local bus
bursting is desirable.
