s

Posted 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.

SMARTarget Flexibility Features

s

Programmable Local Bus operates up

to 60MHz and supports both non-

multiplexed and multiplexed 32-bit

address/data protocol, and Dynamic

Local Bus width control allowing slave

accesses of 8-,16- or 32-bit devices.

s

Supports 5 PCI to Local Address

spaces. These spaces (Space 0,1,2,3 and

Expansion ROM Spaces) allow a PCI

Bus Master to access the local memory

spaces with individually programmable

wait states, bus width, and burst

capabilities.

s

The PCI 9030 has 9 programmable

General Purpose I/Os which may

be used for a variety of purposes.

s

Four programmable Chip

selects eliminate decode logic.

s

CompactPCI Hot Swap Ready

s

Supports Automatic on-the-fly Big

Endian and Little Endian conversion

for all operations and data types.

s

Interrupt Generator can assert PCI inter-

rupts from external and internal sources.

s

Fully supports the Vital Product Data

(VPD) PCI v2.2 extension including New

Capabilities Structure. Provides an alter-

nate access method for user or system

defined parameters or configuration data.

s

PCI 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.

s

PCI 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

on the Local bus. This allows for a higher

throughput for conditions in which the

PCI clock frequency is slower than the

Local clock frequency or when Local bus

bursting is desirable.

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.

SMARTarget Performance Features:

s

PCI v2.2 Compliant 32-bit, 33MHz

Target Interface Chip enabling PCI Burst

Transfers up to 132Mbytes/second.

s

Up to 60MHz Local Bus operation

enabling burst transfers up to

240Mbytes/second

s

PCI 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.
