Design win; DSP IP from CEVA in V2X vehicle-to-everything chipset

April 28, 2016 // By Graham Prophet
DSP IP vendor CEVA has disclosed that its CEVA-XC DSP is employed in Autotalks’ - provider of integrated V2X chipsets - second-generation V2X communications solution supporting concurrent IEEE802.11p and IEEE802.11a/b/g/n/ac operation.

Autotalks (Kfar Netter, Israel) has licensed and deployed the CEVA-XC communication DSP in its upcoming second-generation Vehicle-to-Everything (V2X) chipset. V2X technology connects vehicles to other vehicles (V2V), infrastructure (V2I), motorcycles (V2M) and pedestrians (V2P) within wireless range for safety and mobility applications, such as sharing advanced warnings of unseen hazards or coordinating with traffic signals to minimize queuing. The United States Department of Transportation (USDOT) is expected to publish a Notice of Proposed Rulemaking (NPRM) mandating the installation of V2X in new light vehicles.


Autotalks’ second-generation V2X processor supports mobility-optimized IEEE802.11p communication, operating on the 5.9 GHz band allocated for Intelligent Transportation Systems (ITS) applications, along with IEEE802.11a/b/g/n/ac functionality. The CEVA-XC communications processor enables Autotalks to implement the PHY layer and specific elements of the MAC layer on the DSP, allowing scalable V2X use cases. The implementation supports concurrent dual-channel operation, either two different IEEE802.11p channels or IEEE802.11p and IEEE802.11a/b/n/ac, as well as optimal IEEE802.11p diversity operation. The solution outperforms all SAE2945/1 requirements. The CEVA-XC also incorporates a power scaling unit (PSU) that enables application-specific low power modes, ensuring the chipset is finely tuned for power efficiency.


Amos Freund, VP R&D at Autotalks, commented: “We are pleased to announce CEVA as a key technology partner for our second-generation V2X chipset. The CEVA-XC DSP enables us to deliver best-in-class performance, manifested in superior performance in high-mobility, and even greater functionality and power efficiency in a highly cost-effective V2X communications solution. IEEE802.11a/b/g/ac inclusion enables new use-cases such as dealership firmware update, vehicle-to-home synchronization and even meshes connectivity. ”
