Samsung to Benefit from ARM and National Semiconductor Power Management Collaboration
Share:
SANTA CLARA, California, and CAMBRIDGE, England, June 21/ --
- Samsung Will Offer Extended Battery Life to Mobile Phones Through Their
Highly Integrated Application Processors Incorporating the Advanced Power
Controller
National Semiconductor Corp. [NYSE:NSM] and ARM [(LSE:ARM);
(Nasdaq:ARMHY)] today announced that Samsung [KSE:005930] has become the
first ARM® Partner to publicly announce its license of the National
Semiconductor PowerWise® technology, specifically the Advanced Power
Controller (APC(TM)). This technology will enable Samsung to offer customers
faster, feature-rich mobile phone applications, incorporating "intelligent"
power control for increased battery efficiency.
National Semiconductor's PowerWise technology features a synthesizable
AMBA® methodology-compliant macrocell called the APC, which includes a
hardware performance monitor. This combination allows the APC block to
automatically compensate and minimise the voltage supply based upon
real-time, on-chip system conditions. This results in reduced system power
and energy consumption for extended battery life. APC technology, in
conjunction with a dynamic voltage and frequency scaling SoC and ARM
Intelligent Energy Manager (IEM(TM)) Software, can further reduce power and
energy consumption demands upon the battery by as much as 25 percent to 30
percent.
The APC communicates to an external Power Management Unit (PMU) through
the open-standard PWI interface® (PWI) (www.pwistandard.org). The PMU then
delivers the lowest level of required voltage to the SoC, minimising active
and static system power and energy consumption.
"Today's leading portable device manufacturers need to ensure that
consumers are able to enjoy high-data rate features and extended battery
life," said Ravi Ambatipudi, director of advanced power management products,
National Semiconductor. "By combining PowerWise technology and PWI, Samsung
will be able to deliver the benefits of extremely power and energy-efficient
SoC semiconductor integrated circuits to the mobile phone market."
The APC forms an integral part of the ARM IEM technology, which includes
ARM Artisan® Physical IP, AMBA 3 AXI(TM) interconnect, IEM software and IEC
hardware.
"The collaboration between ARM and National Semiconductor is designed to
bring technologies to market that deliver increased power and energy
efficiency to mobile and wireless devices," said Kevin McIntyre, IEM product
manager, ARM. "The continuing collaboration between ARM and National
Semiconductor will help realise the full performance potential of advanced
mobile phones, enabling these rich new applications."
Availability
National Semiconductor's AMBA technology-compliant PowerWise technology,
APC, is available for licensing through ARM or National Semiconductor for use
with any ARM processor. The ARM IEM technology is available today from ARM.
There are currently three IEM technology-enabled processors: the
ARM1176JF-S(TM) processor, the ARM1176JZF-S(TM) processor, and the ARM11(TM)(TM)
MPCore(TM) multiprocessor. The technology is also available in the Cortex(TM)
family of processors.
