Demand paging allows for building "NAND only phones", using low cost NAND flash memory, which reduces handset cost by up to two dollars
February 14, 2005, Stockholm, Sweden – Enea Embedded Technology today announced the availability of demand paging for its wireless software platform, OSE for Wireless Devices. Demand paging reduces wireless handset cost by roughly two dollars by enabling the system software (including the operating system), coding and decoding software, and all types of applications to execute from NAND flash memory, which is substantially cheaper than conventional NOR flash.
“Reducing memory requirements is the most significant cost-saving factor for mobile handset manufacturers,” said Adrian Leufvén, Vice President Marketing at Enea Embedded Technology. “When using OSE as the software platform for mobile phones, manufacturers can instantly and dramatically lower their bill of materials while at the same time increasing the design flexibility and functionality of their mobile handsets”.
OSE for Wireless is a compact, real-time, high-availability software platform optimized for cost-sensitive wireless devices with limited memory and processor resources. Unlike competitive wireless operating systems, OSE can host both baseband control and application software, which reduces handset cost and complexity by reducing the number of processors and operating systems required for the handset. OSE also features a crash safe file system with flash support, a power management system that extends battery life, and dynamic download capability, which enhances mobile device flexibility by enabling new applications to be downloaded to handsets as they operate in the field.
