DEVELOPMENT TOOLS
The ADSP-TS201S processor is supported with a complete set
of CROSSCORE
including Analog Devices emulators and VisualDSP++
opment environment. The same emulator hardware that
supports other TigerSHARC processors also fully emulates the
ADSP-TS201S processor.
The VisualDSP++ project management environment lets pro-
grammers develop and debug an application. This environment
includes an easy to use assembler (which is based on an alge-
braic syntax), an archiver (librarian/library builder), a linker, a
loader, a cycle-accurate instruction-level simulator, a C/C++
compiler, and a C/C++ runtime library that includes DSP and
mathematical functions. A key point for theses tools is C/C++
code efficiency. The compiler has been developed for efficient
translation of C/C++ code to DSP assembly. The DSP has archi-
tectural features that improve the efficiency of compiled C/C++
code.

The VisualDSP++ debugger has a number of important fea-
tures. Data visualization is enhanced by a plotting package that
offers a significant level of flexibility. This graphical representa-
tion of user data enables the programmer to quickly determine
the performance of an algorithm. As algorithms grow in com-
plexity, this capability can have increasing significance on the
designer’s development schedule, increasing productivity. Sta-
tistical profiling enables the programmer to nonintrusively poll
the processor as it is running the program. This feature, unique
to VisualDSP++, enables the software developer to passively
gather important code execution metrics without interrupting
the realtime characteristics of the program. Essentially, the
developer can identify bottlenecks in software quickly and effi-
ciently. By using the profiler, the programmer can focus on
those areas in the program that impact performance and take
corrective action.
Debugging both C/C++ and assembly programs with the
VisualDSP++ debugger, programmers can:
The VisualDSP++ IDE lets programmers define and manage
DSP software development. Its dialog boxes and property pages
let programmers configure and manage all of the TigerSHARC
processor development tools, including the color syntax high-
lighting in the VisualDSP++ editor. This capability permit
programmers to:
The VisualDSP++™ Kernel (VDK) incorporates scheduling and
resource management tailored specifically to address the mem-
ory and timing constraints of DSP programming. These
capabilities enable engineers to develop code more effectively,
eliminating the need to start from the very beginning, when
developing new application code. The VDK features include
Threads, Critical and Unscheduled regions, Semaphores,
Events, and Device flags. The VDK also supports Priority-based,
Preemptive, Cooperative and Time -Sliced scheduling
approaches. In addition, the VDK was designed to be scalable. If
the application does not use a specific feature, the support code
for that feature is excluded from the target system.
Because the VDK is a library, a developer can decide whether to
use it or not. The VDK is integrated into the VisualDSP++™
development environment, but can also be used via standard
• View mixed C/C++ and assembly code (interleaved source
• Insert breakpoints
• Set conditional breakpoints on registers, memory,
• Trace instruction execution
• Perform linear or statistical profiling of program execution
• Fill, dump, and graphically plot the contents of memory
• Perform source level debugging
• Create custom debugger windows
• Control how the development tools process inputs and
• Maintain a one-to-one correspondence with the tool’s
and object information)
