Low-power IP runs on Samsung process
Samsung is offering ARM Metro low-power products, part of its Artisan family of physical IP, for 65nm low-power process that is a part of the Common Platform enablement.
IP is ready for Chartered/Samsung 65nm process
ARM Advantage physical IP is made available on the 65nm generic process for the Common Platform.
National Semiconductor's PowerWise technology features a synthesisable 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 on real-time, on-chip system conditions.
This results in reduced system power and energy consumption for extended battery life.

Development of Java card uses secure technology
Embedded with a multi-tasking kernel, DNP's Java Card OS can run real-time multiple applications, on a priority basis, with maximum security.
APC technology, in conjunction with a dynamic voltage and frequency scaling SoC and ARM Intelligent Energy Manager (IEM) software, can further reduce power and energy consumption demands on the battery by as much as 25 to 30%.
The APC communicates to an external power management unit (PMU) through the open-standard PWI interface.
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-datarate 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 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".
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 processor, the ARM1176JZF-S processor, and the ARM11 MPCore multiprocessor.
The technology is also available in the Cortex family of processors.
