EL DORADO HILLS, Calif. & WOLFSBURG, Germany -- May 21, 2013

The Embedded Microprocessor Benchmark Consortium (EEMBC) today announced an
expanded working group project with the Volkswagen Group to establish an
energy-efficiency benchmark for microcontrollers aimed at making automotive
end products more energy aware and more robust.

With increasing fuel costs, there is a growing emphasis on reducing energy
consumption and improving fuel economy in automobiles. Simultaneously, there
is also an on-going requirement to ensure the highest levels of robustness in
any automotive product. Microcontroller efficiency (optimizing both
performance and energy) is a critical parameter with far-reaching
consequences, especially with the rising number of microcontrollers in the
car. The working group project, to augment results originally produced in
2011, is being chaired by Volkswagen and currently joined by eleven top-tier
semiconductor vendors including Freescale, Fujitsu, Infineon, Microchip, NXP,
Renesas, STMicroelectronics, and TI. Already, the effort has yielded a full
working specification for measuring performance and energy efficiency of
automotive microcontrollers under various low-power operating conditions.
EEMBC has also developed a prototype of this benchmark implemented on several
key semiconductor evaluation boards.

"We’re pleased that Volkswagen is continuing its important leadership role
with the consortium and look forward to the insight they and the working group
will provide to help EEMBC define and create our next-generation automotive
benchmark suite,” said EEMBC President Markus Levy. “Volkswagen has been a
long-time leader in the automotive industry and as chair of this project, they
will continue to provide inputs to ensure the real-world value of this
benchmark and subsequent versions that will address increasing microcontroller
complexity and robustness requirements. We also expect that Volkswagen’s
participation will produce a roadmap for automotive and other end-market
manufacturers to get involved with EEMBC to guarantee equitable and valuable
benchmarks for their industry.”

“As a world leader in advanced automotive systems, Volkswagen is continuing to
chair the EEMBC Automotive working group and lend its expertise to ensure that
the new benchmark reflects real-world system-design conditions and leads to
improved efficiency,” said Volkswagen’s head of electric and electronic
development, Dr.Volkmar Tanneberger. “Following completion of this new
benchmark suite, we will demand the Tier 1 suppliers and semiconductor vendors
to provide results for the microcontrollers that will be integrated into the
next generation of electronic modules.”

EEMBC’s first-generation automotive benchmark suite, AutoBench, was designed
to focus on the CPU’s processing power, measuring the time required to
complete specific algorithms. The new benchmark suite adds new tests to
measure CPU performance while simultaneously monitoring peripherals and energy
usage. Individual tests of the microcontroller measure the power consumption
of the CPU and peripherals under various loads, the amount of time that it
spends in low-power modes under various CPU/peripheral loads, and the time
required to wake the MCU from its various low-power states to resume
processing. Moreover, the working group will align this benchmark suite with
the AUTOSAR development partnership, utilizing the Microcontroller Abstraction
Layer (MCAL) to interface to the underlying microcontroller hardware.

This benchmark specification will be open to all world-wide car manufacturers
and tier 1 suppliers, and EEMBC encourages everyone in the ecosystem to join
the effort to develop subsequent phases of this benchmark. Contact EEMBC for
more details.

About Volkswagen Group

The Volkswagen Group with its headquarters in Wolfsburg is one of the world’s
leading automobile manufacturer and the largest carmaker in Europe.
In 2012, the Group increased the number of vehicles delivered to customers to
9.276 million (2011: 8.265 million), corresponding to a 12.8 percent share of
the world passenger car market. The Group comprises twelve brands from seven
European countries: Volkswagen Passenger Cars, Audi, SEAT, ŠKODA, Bentley,
Bugatti, Lamborghini, Porsche, Ducati, Volkswagen Commercial Vehicles, Scania
and MAN.

Each brand has its own character and operates as an independent entity on the
market. The product spectrum ranges from motorcycles to low consumption small
cars and luxury vehicles. In the commercial vehicle sector, the products
include ranges from pickups, buses and heavy trucks. The Group’s goal is to
offer attractive, safe and environmentally sound vehicles which can compete in
an increasingly tough market and set world standards in their respective


EEMBC, the Embedded Microprocessor Benchmark Consortium, founded in 1997,
develops and certifies real-world benchmarks and benchmark scores to help
designers select the right embedded processors for their systems. Every
processor submitted for EEMBC benchmarking is tested for parameters
representing different workloads and capabilities in communications,
networking, smartphone and other connected devices, office automation,
automotive/industrial, embedded Java, and network storage-related
applications. With members including leading semiconductor, intellectual
property, and compiler companies, EEMBC establishes benchmark standards and
provides certified benchmarking results through the EEMBC Technology Center.
