 Internet
Machines' Development Workbench is
a full featured, graphical, and easy-to-use
software development kit that allows
rapid development of application-specific
fast path forwarding code for Internet
Machines' NPE10 network processor.
The kit provides a complete, clock
cycle-accurate software simulator
of the NPE10, along with tools for
designing, debugging, and optimizing
fast path code. The Development Workbench
enables development of forwarding
code early in the system development
cycle, greatly accelerating system
time to market.
Easy
to use. The Development Workbench
provides a single threaded, single-processor
programming model and interfaces to
a wide range of standard tools to
simplify code designs.
Full featured. The Workbench
includes traffic generation tools
for creating simulated real-world
traffic patterns, which allows designers
to evaluate how their forwarding code
performs under stress. Debugging tools
test and optimize the execution of
forwarding code, and performance analysis
tools monitor system behavior and
isolate system bottlenecks. An application
library includes pre-coded modules
for critical functions common in network
switching equipment and sample reference
code for data path applications. A
Tcl command line interface (CLI) is
also available for more advanced programming.
Since
the NPE10 is fully software programmable,
the Workbench facilitates quick response
to specific customer needs, increasing
customer satisfaction. It also speeds
the development of
features required to secure a competitive
edge in the growing high-speed networking
market.
