CEVA And Antcor Announce Low Power, Wi-Fi 802.11ac Reference Architecture For The New CEVA-XC4000 DSP Architecture Framework


MOUNTAIN VIEW, Calif., Feb. 21, 2012 /PRNewswire/ -- CEVA, Inc. (NASDAQ: CEVA); (LSE: CVA), the leading licensor of silicon intellectual property (SIP) platform solutions and DSP cores and CEVA-XCnet partner Antcor S.A., a leading provider of software baseband IP for the communications and connectivity chip industry, announced today a new software-based, reference architecture targeting multi-mode Wi-Fi 802.11ac mobile stations (STA). With the new 802.11ac Wi-Fi standard yet-to-be ratified, and numerous other derivatives including 802.11af, 802.11p and Wi-Fi Direct, this software-based approach enables complete flexibility to address changes in the standard and support for various use-cases through software updates. Based on the new CEVA-XC4000 DSP architecture framework, this scalable Wi-Fi reference architecture is ideal for cost-efficient, ultra-low power applications, requiring as small as 1.5 sqmm die area at a 28nm process.

Eran Briman, vice president of marketing at CEVA stated, "The advent of the 802.11ac standard poses new challenges for the development of multi-standard, high performance Wi-Fi enabled SoCs. The processor requirements to deliver this increased performance are exponentially higher and existing hardwired design approaches for multi-standard Wi-Fi solutions are no longer efficient. Our new CEVA-XC4000 based 802.11ac reference architecture designed in collaboration with CEVA-XCnet partner Antcor easily addresses these performance requirements, and provides full flexibility to support the 802.11ac standard and any other Wi-Fi standard, in software. This high performance reference architecture is an example of the versatility of our new CEVA-XC4000 DSP series to address any advanced communication standard in software."

The Wi-Fi 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 867Mbps using a 4x2 MIMO beam-forming with 256-QAM modulation support, and can be scaled to support up to 1.7Gbps. The reference architecture supports a wide range of Wi-Fi 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.
