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.
interface with a programmable local bus. Integrating the latest in I/O technology,
the PCI 9080 contains an Intelligent I/O (I 2 O) messaging unit in hardware that
allows high performance and compatible software implementations of the I 2 O
bus protocol specification.
wide variety of processors, controllers and memory subsystems. Combined with
the PCI 9080RDK reference design kits, PCI SDK and I 2 O software development
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.
