Technology
Overview
Reach the full potential of your
communications application with CodeWarrior
v10.0 for Power Architecture
®
development
tools for the Freescale QorIQ processors built
on Power Architecture® technology. Integrated
within an Eclipse framework, the CodeWarrior
Development Studio for Power Architecture
technology combines GNU build tools and
highly advanced asymmetric multiprocessor
(AMP)/symmetric multiprocessor (SMP) Linux
®
multicore debugging with software analysis
capabilities, allowing you to build, debug
and maximize the performance of Power
Architecture-based multicore applications.
• Support for Linux application and kernel
development (tool capabilities vary with the
targeted processor)
Software Analysis
i
Several of Freescale’s QorIQ processors
include advanced features such as packet
processing accelerators (i.e., parts of DPAA
on the P4080). The CodeWarrior Development
Studio for Power Architecture technology
provides software analysis capabilities that
give developers the tools they need to tune
application performance or debug complex
timing issues issues.
Eclipse IDE
• Common IDE platform
• Open standard
Common framework
Leverages larger ecosystem
• Extensible
Eclipse-based tools enable extensions
via plug-ins
• Ease of use
Common look and feel across Freescale
Eclipse-based CodeWarrior platforms
Eclipse perspectives
• Customizable window layout
Trace Analysis
For applicable target devices, CodeWarrior
trace tools provide developers with timing
information for:
• Program flow trace
• Data access
• Packet processing events (available for
some processing units)
• Linux kernel events using the LTTng
Highlights
• Feature-rich, Eclipse-based IDE
• Multicore AMP/Linux SMP debugger with
multicore run-control commands
• Highly advanced software analysis tools,
including program and data path acceleration
architecture (DPAA) trace tools and extended,
integrated support for popular open source
tools such as the GNU Linux Trace Tool
(LTTng), OProfile and Valgrind

The software analysis capabilities vary by the processor that is being targeted. This is partially the
result of the fact that different processors have different capabilities, including different accelerators
and different debug, trace and event counting capabilities.
Performance Analysis
Performance analysis tools provide another
way to non-intrusively debug functional and
performance application issues.
Tools include:
• Configuration of event counters
• Pre-defined “metrics” that provide
meaningful performance information for
networking applications. Examples include:
Cache hit/miss ratios
Branch hit/miss ratios
Stall cycles per address collision
Instructions per cycle
• Various views for event data, including:
Average values
Timelines
Raw data
CodeWarrior Debugger
CodeWarrior multicore debugging support
allows the developer to issue commands
across user-defined subsets of cores. Special
support for Linux kernel and application
development is also included.
Multicore debugging features include:
• Multicore run, start and stop commands
• Multicore reset
• SMP debugging
• AMP debugging
• Support for debugging applications using
Freescale hypervisor or Light Weight

Build Tools
The CodeWarrior Development Studio v10.0
for Power Architecture technology includes
GNU build tools for all e500mc-based cores.
For e500v2-based processors, the Freescale
CodeWarrior build tools generate optimized
code for C.
