CEVA-XC High-Performance, Low-Power DSP Cores for Advanced Wireless Communications
Digital signal processing is a key technology that is powering many of today’s fastest growing electronics markets. CEVA is the world’s leading licensor of programmable?DSP Cores?andPlatforms and Solutions.
The CEVA-XC family of DSP cores features a combination of VLIW (Very Long Instruction Word) and Vector engines that enhances typical DSP capabilities with advanced vector processing. Based on the architecture of the CEVA-X DSP family, the CEVA-XC family of DSP cores incorporates up to four modular Vector Communication Units into the CEVA-X framework. The scalable CEVA-XC architecture offers a selection of highly powerful communication processors targeting the most demanding wireless applications and use cases, enabling software-defined modem design with minimal hardware. With its innovative programmable approach, the CEVA-XC family offers high flexibility that supports a large number of wireless standards on a single programmable platform, thereby significantly reducing development cost and time to market.
The CEVA-XC architecture is supported by the CEVA-toolbox, an optimizing tool chain that includes a C-Compiler with dedicated support for Vector Processors. Alongside the DSP platform and tool chain, CEVA also offers a complete set of communication and DSP libraries as well as complete reference architectures for terminals and wireless infrastructure.
