Debugging highly parallel hardware/software applications introduces
special challenges. During desktop simulation, CoDeveloper's unique Application
Monitor makes it possible to observe your application as it runs (whether
under the control of a debugger or when running as a native development
host application) and view outputs and other information collected as
a result of instrumenting your code. Application monitoring is an effective
way to see where potential data bottlenecks are occurring, to identify
possible deadlock conditions and to zero in on problems your application
may have with data movement, process synchronization and load balancing.
The Application Monitor lets you to observe the application's processes
and buffered data flowing through the system.
By adding Impulse C instrumentation functions to your application, you can
more easily make sense of how your application operates and quickly find
errors. In a typical monitoring scenario, each process in the application
creates one or more monitor log windows that are used to display formatted
or unformatted text messages. In addition, the Application Monitor displays
a graphical view of the state of buffered data streams, making it easy for
you to identify and improve potential data bottlenecks.
Log windows for each running process help instrument and debug highly
parallel applications.
For applications consisting of large numbers of processes, and in particular
applications that include arrays of processes (such as heavily pipelined
or systolic array applications), the Application Monitor can provide visibility
during debugging that would otherwise be impractical or impossible.
And by observing when (and under what conditions) your data buffers become
full and your processes are blocked you can make better design decisions
with the goal of optimizing overall application performance.
Log windows can represent each instance of a process being
replicated in a pipelined array.
CoDeveloper provides C to RTL design and compilation for
various FPGA platforms including Xilinx and Altera. It enables
you to create your own FPGA-based custom platform and to target
systems with external processors, including DSPs.
