JBenchmark ARM CPU Estimator Gauges the
Generation of Processor and Clock
Frequency of Mobile Phones With
Unique Java-Based Software
Kishonti Informatics, the
worldwide leader of mobile performance benchmarking, has
announced today
the JBenchmark ARM(R) CPU estimator (ACE), which measures the
performance
of Java (Java ME)-enabled mobile devices.
"The JBenchmark ACE meets the growing demand from consumers
and
developers for more transparency in mobile architectures and
helps to
explain the wide differences in mobile application
performance," said
Stuart Robinson, director, Handset Component Technologies,
Strategy
Analytics. "According to our latest research, virtually all
mobile phones
incorporate at least one ARM processor, and almost 1.2 billion
handsets in
use are Java-enabled, meaning that ACE can compare the
performance of
nearly all mobile devices."
JBenchmark ACE software is free to download and once started,
reveals
the type of processor, clock speed and profiles the Java
Virtual Machine
(VM) used in that mobile device. Besides supporting Mobile
Information
Device Profile (MIDP) Java environments, the JBenchmark ACE
also supports
the DoJa platform developed by DoCoMo and used by millions of
phones in
Asia and Europe.
"The compiled results demonstrate the large variation in
processor
clock frequencies across different mobile phones. The gap
between the
slowest and fastest devices currently on the market is more
than a factor
of 10, which considerably alters the user experience," said
Laszlo
Kishonti, General Manager, Kishonti Infomatics. "The
JBenchmark ACE results
page reveals that many voice-centric phones use an ARM7(TM)
family
processor at 40MHz, in contrast with high-performance open
platform devices
using ARM9(TM) or ARM11(TM) family processors generally
running between
300MHz and 600MHz, such as the HTC TyTN running at 400MHz."
"Feature-rich phones, including smartphones, is by far the
fastest
growing mobile handset segment. Informa Telecoms & Media
expects sales of
these devices to reach 55 percent of total handset sales by
the end of
2007. Mobile handsets are rapidly evolving into more powerful
computing
devices," said Dr. Malik Kamal-Saadi, principal analyst at
Informa Telecoms
& Media. "The selection of ARM processor type and Virtual
Machine are
fundamental elements that determine factors such as software
compatibility,
OS boot time, games performance, and how quickly other
applications like
music players and photo galleries are opened. Therefore, there
is a clear
need to understand the relative performance of different
platforms as this
directly affects the user experience."
Estimation Methodology
The JBenchmark ACE can identify all major ARM processor
generations,
including the ARM7, ARM9 and latest ARM11 processor families.
Each ARM
processor class has different performance profiles and
differing range of
clock rates which are all reported back by the JBenchmark ACE.
Using the
JBenchmark ACE, it is possible to see that the ARM11 processor
family is
being used in the newest most powerful mobile devices,
including the Nokia
N93, which was voted the European Media Phone of the Year
2006-2007 by the
European Imaging and Sound Association (EISA), Europe's
largest multimedia
press organization. Similarly, it is evident that the ARM7
processor family
is still favored for voice-centric phones.
As there are no native Java methods to obtain information
regarding an
embedded processor, the JBenchmark ACE uses innovative
measurements,
statistical methods and a database of benchmarked devices to
get a precise
estimation of the underlying processor class and clock
frequency. Each
result is classified and compared to all results held in the
database to
make sure the estimation is realistic. In addition, the ACE
adaptive
estimator engine improves automatically upon conducting each
measurement,
which increases the precision of the future results.
Accuracy and Transparency
The JBenchmark ACE also creates a very detailed profile on
the Java VM,
based on distinct groups of Java acceleration strategies such
as: just in
time compilers (JIT), ahead of time compilers (AOT),
interpreted VMs and
hardware accelerated VMs such as ARM Jazelle(R) technology.
Knowing the
Java VM used by the mobile device greatly enhances the
estimation precision
and also provides users with the context for the performance
results.
The JBenchmark ACE targets 90 percent accuracy, meaning that
more than
90 percent of the processor clock frequencies are estimated
correctly to
within 10 percent margin of error.
JBenchmark ACE estimations are based on two components:
- The JBenchmark ACE client application runs on the mobile
device,
collects raw measurement data and sends it back to the server
for
calculating the final results, which are reported back to the
user.
- The JBenchmark ACE server-side engine estimates the final
results
based on the raw data received from clients. The engine
updates itself
automatically with every new result received to increase
precision.
The JBenchmark ACE database already contains more than 250
tested
devices and new results are automatically added into the
database.
