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 and Platforms and Solutions.
The CEVA-XC family of DSP cores features a combination of VLIW (Very Long Instruction Word) and Vector engines that enhance 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 supports a large number of wireless standards on a single programmable platform, thereby significantly reducing development cost and time to market while offering high flexibility for future proof design.
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.
Which CEVA-XC DSP core is right for me?
The CEVA-XC5 DSP vector processor is the newest and smallest member of the CEVA-XC family, the industry’s most widely adopted DSP vector architecture.
Designed to address use cases where the latest LTE MTC Cat-0 or Cat-M standards can be used concurrently with Wi-Fi 802.11n, PLC, 802.15.4g, ZigBee/Thread, GNSS or any other emerging IoT communications standard including NB-IoT, LPWAN, or Wi-Fi 802.11ah, this new DSP processor delivers industry-leading performance and exemplary power efficiency for even the most cost, power and die size constrained devices.
As an example, the CEVA-XC5 DSP is 40% smaller than any previous generation CEVA-XC processor and deploys a new IoT-optimized Power Scaling Unit (PSU) which enables it to achieve up to 70% lower dynamic power consumption. This unique capability is realized by incorporating specific elements into the PSU such as five power scaling modes (Dynamic Power Save, Stand-by, Scale Down, Data Retention and Power Down) that allow the CEVA-XC5 to take advantage of new Cat-0 and Cat-M features such as Power Saving Mode (PSM) and long DRX to further reduce power.
The CEVA-XC8 DSP vector processor is one of smallest members of the CEVA-XC family, the industry’s most widely adopted DSP vector architecture.
Designed to address use cases where the latest LTE MTC Cat-1 can be used with Wi-Fi 802.11n, PLC, 802.15.4g, ZigBee/Thread, GNSS or any other emerging IoT communications standards. This new DSP processor delivers a good balance between high performance, power efficiency and low cost.
A highly powerful and scalable multi-mode communication processor for advanced wireless applications.
The fourth generation of the widely licensed CEVA-XC architecture, the CEVA-XC4500 is optimized for wireless terminals and infrastructure applications, including macro-cells, small cells, cloud-RAN and DFE. The CEVA-XC4500 delivers highly powerful fixed point and floating point vector capabilities supplying the performance and flexibility demanded by next generation wireless applications.
