ORANGE COUNTY, Calif. -- October 22, 2012

IAR Systems® announced that benchmarks presented by the Embedded
Microprocessor Benchmark Consortium (EEMBC®) show that the Renesas Electronics
RX600 series of microcontrollers (MCU) together with the IAR Embedded
Workbench® development tool suite provides faster performing code than ever
before, achieving a score of 3.12 CoreMarks/MHz on the industry-standard EEMBC
CoreMark® benchmark.

“We have been working closely with IAR Systems to provide MCU solutions that
allow embedded systems designers to take full advantage of the possibilities
offered by our RX MCU family, and we are excited for the new EEMBC benchmark
results,” said Ritesh Tyagi, senior director, Microcontroller Products &
Solutions Marketing, Renesas Electronics America. “The EEMBC CoreMark results
are a validation of our collaboration to provide customers with
high-performance MCUs and powerful development tools that help them manage
greater design complexity and shorter design cycles.”

“Our customers have come to expect nothing but the most efficient
optimizations from our compiler,” commented Mats Ullström, Director of
Products and Services, IAR Systems. “Thanks to our close collaboration with
Renesas, we are able to provide the technology that enables developers to make
the most of the powerful RX family, and this is confirmed by the results
presented by EEMBC.”

The CoreMark benchmarks were run on an RX62N MCU. Based on Renesas’
high-performance RX core, the RX62N MCU is part of the wider RX600 series,
which includes devices from 32KB up to 2MB of on-board flash and numerous
variants, featuring a comprehensive set of on-chip communications and control
functions. The RX62N and RX63N groups, for instance, include Ethernet, USB 2.0
(host and device) and CAN, and meet the connectivity needs of industrial
applications such as building management and factory automation systems within
smaller form-factor, cost-effective devices. All RX600 devices deliver the
same cutting-edge performance, thanks to the RX core operating from its 0 wait
state flash up to 100MHz.

The latest version of IAR Embedded Workbench for RX, released in June 2012,
included major enhancements to the already very efficient code optimization
techniques. Now, the techniques have been even-further refined. The
optimizations for code size and execution speed provided by the IAR C/C++
Compiler® perform on multiple levels, global as well as core/target-specific.
The developer is able to tune the optimizations to achieve the best possible
configuration for the application at hand. Major functions of the optimizer,
such as loop unrolling and function inlining, can be controlled individually,
and by setting different optimizations for different parts of the code, the
right balance between size and speed can be achieved. IAR Embedded Workbench
features multi-file compilation, which allows the optimizer to operate on a
larger set of code and can result in smaller code, and linker-level removal of
unused code.

IAR Systems is the only tool vendor to provide high-performing tools for the
entire line-up of Renesas MCUs. In total, more than 4000 Renesas devices are
supported by IAR Embedded Workbench, including all RX devices. The scores were
achieved using a pre-release of the upcoming version, 2.41, that will be made
available to customers in November.

About EEMBC

CoreMark was developed by EEMBC, a non-profit industry association for
embedded microprocessor benchmarks. CoreMark is a simple, yet sophisticated,
benchmark that is designed specifically to test the functionality of a
processor core. Running CoreMark produces a single-number score, allowing
users to make quick comparisons between processors. CoreMark scores are
published at www.coremark.org.
