Network Processor Device Driver for Linux
The Customer
The customer is a fabless semiconductor company providing high-speed
highly-integrated network processors, which integrate both packet processing and
classification with embedded search engines on a single chip.
This highly flexible 7-layer processing enables a wide range of applications to
deliver advanced services for the metro, carrier edge and core/enterprise
backbone at wire speed.
The Product
The single-chip 10Gbps network processor offers fully programmable 7-layer
packet classification, modification, forwarding and policing at wire speed.
Its unique technology combines packet processing and classification in a
full-duplex chip.
For Software Application Vendors, the network processor is available as an
AdvancedTCA (Advanced Telecom Computing Architecture) blade or as a boxed
systems, including a Pentium-III PrPMC, for facilitating the development of the
control path software via APIs that interface with the network processor.
The APIs include configuration, microcode loading, creation and maintenance of
lookup structures, sending and receiving frames to and from the network
processor, as well as configuration and access to the statistics block.
The Challenge
Ximpo Group's Embedded and Kernel experts were hired to develop the Linux
Kernel driver for the Network Processor, and to port the BSP (Board Support
Package).
The BSP was ported from the customer's VxWorks-based version, and a Linux Device
driver was developed to directly control and exchange data with the Altera FPGA
and the Network Processor.
Ximpo Group's experts delivered the BSP and Device Driver in under three
calendar weeks, allowing the customer to finalize integration with the toolset
and be ready for Quality Assurance in under 5 weeks.
The work concluded with knowledge transfer, and escorting the customer with the
support of Beta-testers until market-deployment.
Since Ximpo Group delivered the BSP and Device Driver, a new generation of
the network processor has been launched, is manufactured with IBM's leading
CU-11 0.11 micron process and is shipping in production quantities.
As of 2Q2004, the customer has announced the third generation of its network
processors.
