 Challenge:
“MCUs continue to become more complex especially when
creating applications to enable the Smart Society, and
therefore the Software becomes more complex as well.
However, project schedules do not always scale
accordingly.”
 Solution:
“Renesas is introducing an Eclipse-based Integrated
Development Environment, providing powerful and flexible
features that ease and accelerate creation and debugging of
embedded code.”

Quick Recap on Eclipse
 Open source, free of charge IDE platform for C/C++
software development (when combined with CDT)
 Community effort - Collaboration by MANY developers:
IBM, Oracle, Cisco, Intel, etc.
 Overall project management by the Eclipse Foundation
(www.eclipse.org
), founded in 2004
 Extensible plug-in system
 Similar to Firefox Add-ons
 Allows Renesas to add build support for specific MCUs as well as
support for device dependent debug hardware

Allows users to customize their IDE by adding 3
rd
party plug-ins,
e.g. editors, compilers, bug trackers, version control software,
RTOS awareness, etc.

Why Did We Choose Eclipse?
 Eclipse is becoming the de-facto standard IDE for embedded
software development in Europe and the US
 Eclipse is gaining momentum because users can…
 …standardize their development tools
(less training, faster development)
 …take advantage of a large variety of available plug-ins for
embedded development from a large variety of vendors
 …develop their own plug-ins
 …get easier technical support

(main product used by many people)
 …take advantage of numerous mature IDE features
(particularly in editor)

…save money over proprietary development tools
(especially when combined with free GNU compilers)

Eventpoints View – Sets Complex Breakpoints

 Before PC eventpoints: Hardware breakpoints (Address)
 Event Break eventpoints: Trigger on Data Access (R/W)
 Trace eventpoints: Trigger start, stop, and recording of Trace

Combine eventpoints with OR, AND, and SEQUENCE logic to
create complex triggers

Trace View
 Trace acquisition depending on hardware capabilities:
 Branch, Branch and Data, Data
 Presentation modes:
 Bus mode, Disassembly mode, Source mode

Profiling View (new in v1.1)
 e²studio uses the trace data to determine times spent in
each area of code
 This means profiling can be supported by any device /
debugger that supports trace

To view profiling results the Enable Profile Toolbar button
must be enabled
