Software and Development Tools<br />
Code Composer Studio Development Tools for eXpress<strong>DSP</strong> Software<br />
Tuning Tools<br />
Advanced tools designed specifically for<br />
the optimization process are used to<br />
improve execution time, utilize cache<br />
more efficiently and decrease memory<br />
usage. These tools are wrapped with an<br />
interactive advisor that walks the user<br />
through the tuning process specific to the<br />
goals set by the developer.<br />
Debug Within the IDE<br />
CCStudio IDE’s integrated debugger has<br />
<strong>DSP</strong>-specific capabilities and advanced<br />
breakpoints to simplify development.<br />
Conditional or hardware breakpoints are<br />
based on full C expressions, local variables<br />
or CPU register symbols. A General<br />
Extension Language (GEL) script file can<br />
be executed when a particular breakpoint<br />
hits. Global breakpoints are also available<br />
for multiprocessor systems. Developers<br />
can debug code quickly by selectively<br />
stepping into, over or out of C function or<br />
assembly subroutines. CCStudio’s Debug<br />
Rewind capability lets users also step<br />
backwards in their source code to quickly<br />
find and observe application behavior<br />
during a simulation. A ProbePoint,<br />
unique to CCStudio development tools, is<br />
a sophisticated form of a breakpoint. It<br />
allows developers to define a point in the<br />
algorithm where oscilloscope-type functions<br />
can be performed. Unlike a breakpoint,<br />
program, execution resumes after<br />
hitting a ProbePoint and performs the<br />
connected activity (e.g., inject or extract<br />
signal data, observe signals, execute GEL<br />
script). CCStudio IDE also supports popular<br />
external scripting languages such as<br />
Perl and VBA to help developers automate<br />
application testing and validation.<br />
Multi-Target Debug<br />
CCStudio IDE supports the development<br />
of complex systems with multiple boards<br />
or multiple processors on a single target<br />
board. CCStudio’s Parallel Debug<br />
Manager (PDM) provides synchronized<br />
control over multiple processors configured<br />
in single or multiple scan chains. It<br />
can be used to launch individual parent<br />
windows to control each processor. The<br />
Parallel Debug Manager can be used to<br />
broadcast commands to different groups<br />
of CPUs in the JTAG scan path. A global<br />
breakpoint command on one processor<br />
can halt other processors when this<br />
breakpoint is encountered. The Parallel<br />
Debug Manager lets developers open up<br />
separate debug windows for any CPU on<br />
any board in the system. CCStudio’s unified<br />
IDE supports TMS320C2000,<br />
TMS320C5000, TMS320C6000 <strong>DSP</strong>,<br />
DaVinci and OMAP processor platforms<br />
in one simple installation enabling<br />
a variety of configurations such as multiple<br />
<strong>DSP</strong>, heterogeneous <strong>DSP</strong> combinations,<br />
SOC and discreet <strong>DSP</strong>/Microcontroller<br />
groupings.<br />
System Analysis<br />
CCStudio also delivers standalone systemlevel<br />
analysis tools for DaVinci processor<br />
systems. These system analysis tools<br />
enabled by eXpress<strong>DSP</strong> data visualization<br />
technology provide developers with a<br />
birds-eye view of system-level interactions.<br />
The TMS320DM644x SoC Analyzer<br />
helps developers identify bottlenecks that<br />
were previously very difficult to find. The<br />
SoC Analyzer is non-invasive and aids in<br />
analyzing and identify problems by capturing<br />
and graphically displaying system<br />
interactions, local and load distributions<br />
and data throughput. As the tasks run on<br />
both the <strong>DSP</strong> and ARM ® cores of the<br />
TMS320DM644x processors, the analyzer<br />
captures and displays the data on a single<br />
timeline. This provides a complete<br />
system view of the application and<br />
