eliminates the tedious process of manually
collecting and comparing data on
each core before optimization begins.
Real-Time Data Exchange (RTDX)
Once algorithms are integrated into
applications, the real-time behavior of
the system must be observed. CCStudio
Development Tools allow the developer
to visualize or debug an application while
it runs in real time. RTDX provides significant
benefits over alternative methods of
system debugging.
RTDX gives developers the industry’s first
DSP system that provides real-time, continuous
visibility into the way target
applications operate in the real world.
RTDX allows developers to transfer data
between the host computer and DSP
devices without stopping their target
application. This shortens development
time by giving developers a much more
realistic representation of the way their
systems operate. RTDX allows designers
to continually monitor their systems and
gain real-time insight into their running
applications.
Interactive Profiling
CCStudio IDE’s interactive profiler makes
it easy to quickly measure code performance
and ensure the efficient use of the
DSP target’s resources during debug and
development sessions. The profiler
allows developers to easily profile all
C/C++ functions in their application for
instruction cycles or other events such as
cache misses/hits, pipeline stalls and
branches. Profile ranges can be used to
concentrate efforts on high-usage areas
of code during optimization, helping
developers produce finely-tuned code.
Profiling is available for ranges of
Assembly, C++ or C code in any combination.
To increase productivity, all profiling
facilities are available throughout the
development cycle.
Real-Time Analysis
Using the real-time analysis capabilities
of CCStudio Development Tools, a developer
can probe, trace and monitor a DSP
application while it runs. These utilities
are based on a real-time link and awareness
between the CCStudio Development
Tools host environment and the target.
Even after the program has been halted,
information already captured through the
real-time analysis tools can provide
invaluable insight into the sequence of
events that led up to the current point of
execution. Real-time analysis tools are
used later in the development cycle when
transitioning from the debug phase to the
runtime phase. They show subtle problems
arising from time-dependent interaction
of program components. Real-time
analysis tools are the software counterpart
of the hardware logic analyzer.
