Flexible Connection to the PCI Bus
For add-in card and embedded system designers and integrators alike, the mis-
sion is clear: reduce the time to integrate new technology and time to market.
Achieving this task requires the latest in I/O technology. PLX Technology, Inc.
is committed to providing complete and proven PCI solutions with our PCI 9080
Bus Master I/O Accelerator interface chip.
PCI 9080 provides a compact, high performance PCI bus master
The PLX
interface with a programmable local bus. Integrating the latest in I/O technology,
the PCI 9080 contains an Intelligent I/O (I O) messaging unit in hardware that
2
allows high performance and compatible software implementations of the I O
2
bus protocol specification.
The highly flexible local bus solution can be configured to directly connect a
wide variety of processors, controllers and memory subsystems. Combined with
the PCI 9080RDK reference design kits, PCISDK and I O software development
2
kits available from PLX, the design-in process is simple and painless with little or
no glue logic. Customers are using the PCI 9080 with IBM PowerPC 40x, Motorola
MPC850/860, Intel i960C/J/H, Hitachi Super H, MIPS R 3000/4000/5000, NEC
V830/831, ARM, Motorola 68XXX, and others. Thoroughly tested and proven,
PLX products have become the gold standard of the industry.
Leading the way in PCI design, the PCI 9080 provides two intelligent DMA
channels with scatter/gather, programmable burst modes, and asynchronous
bus clocks to provide the best PCI throughput available. The versatility of the
PCI 9080 also allows for a local processor to configure other PCI devices in
the system.
While the PCI 9080 is capable of keeping up with the most demanding of
applications and the latest in technology, upward compatibility with existing
PLX PCI I/O accelerators is maintained. The 9080 continues the PLX tradition of
providing the highest performance and fully compatible PCI interface solutions.
