Cores are ready for Magma reference implementation
Magma Design Automation and ARM have developed a reference methodology for RTL-to-GDSII implementation of SoCs that include cores from the ARM9E family of microprocessors.
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.
Wireless networking is expected to be the basis for many applications such as voice communications, home audio/visual entertainment, and other networking areas where the ARM processor performance, flexibility, and industry-leading support will assist Atheros in achieving rapid time to market.
Atheros will take advantage of licensing the world's most popular 32bit architecture in its next-generation systems where 802.11 wireless technologies will play an important role.
"With the 802.11 wireless sector expected to continue growing rapidly over the next few years, it is the strength of our technology that will help us capitalise on this opportunity", said Colin Macnab, Vice President of Marketing and Business Development, Atheros Communications.

"ARM microprocessor cores offer us a strong and highly competitive road map to enable Atheros to maintain our market-leading position".
ARM has a proven architecture supported by a wide range of integration tools and extensive history of successfully working with chip vendors to accelerate designs and products to market.
ARM leads the 32bit CPU market, and Atheros will work to leverage this leadership into existing and new 801.11 technology-based applications.
"The 802.11 wireless market is one of many high-growth sectors that we are targeting", said Mike Inglis, EVP Marketing, ARM.
"We are offering OEMs in this sector a commitment to help meet the increasing need for reduced cost and size, and power-efficient products".
"This partnership with Atheros will enable them to deliver industry-leading products to the wireless networking market and we look forward to developing our relationship further".
The ARM 926EJ-S macrocell features a 32bit RISC CPU with ARM Jazelle Java bytecode acceleration embedded within the core.
The ARM946E-S core includes an ARM9E-S CPU with flexible instruction caches, data caches and TCM (tightly coupled memory) interfaces.
The size of these caches is reconfigurable, as are the memories of the instruction and data TCM, which means that hardware can be tailored to an embedded application.
Both cores implement the ARMv5TEJ instruction set, which includes 16bit fixed-point DSP instructions to enhance the performance of many signal processing algorithms.
