Keywords:WiFi 802.11ac? WiFi reference architecture?

Ceva Inc. and Antcor SA jointly introduced a software-based, reference architecture designed for the pending multimode WiFi 802.11ac mobile stations (STA) that will be easily adapted to numerous other WiFi derivatives, including 802.11af, 802.11p and WiFi Direct, using software updates.

Based on the CEVA-XC4000 DSP architecture framework, this scalable WiFi reference architecture is suited for cost-efficient, ultralow-power applications, requiring a die area as small as 1.5 x 1.5mm on a 28nm process.

The WiFi 802.11ac reference architecture addresses both the PHY and Lower-MAC layers in software with minimal hardware acceleration, to deliver outstanding performance without compromising on power consumption. The solution supports the full channel bandwidth up to 160MHz and offers maximal throughput of 867Mbit/s using 4x2 MIMO beam-forming with 256-QAM modulation support; it can be scaled to support up to 1.7Gb/s. The reference architecture supports a wide range of WiFi standards, including 802.11a/b/g/n/ac, providing customers with ample headroom to add additional features and functionality on the same platform and further differentiate their product offering.

The WiFi 802.11ac reference architecture is supported by CEVA-Toolbox, a complete software development environment, incorporating Vec-C compiler technology for advanced vector processors, enabling the entire architecture to be programmed in C-level. An integrated simulator provides accurate and efficient verification of the entire system, including the memory subsystems. In addition, CEVA-Tool-box includes libraries, a graphical debugger, and a complete optimization tool chain named CEVA Application Optimizer. The Application Optimizer enables automatic and manual optimization applied in the C source code.

CEVA and Antcor's WiFi 802.11ac reference architecture is available today for lead customers.
