The CEVA-XC12 is purpose-built from the ground up to solve the most critical challenges of efficiently implementing 5G, gigabit LTE, MU-MIMO Wi-Fi and other multi-gigabit modems, delivering up to 8x performance improvement and consuming 50% less power than its predecessor, the CEVA-XC4500.

Designed to support future wireless standards with peak data rates of up to 20Gbps under ultra-low latency of 1 millisecond, the CEVA-XC12 has a flexible architecture with multiple optional features so it can be custom configured and scaled to address a wide range of applications. This includes smartphones and other terminals, advanced and centralized access points, small cells, macro cells and cloud RAN (C-RAN). It supports the full gamut of 5G use cases and deployment scenarios, from 80 GHz mmWave down to 450 MHz spectrum bands. In addition to 5G, CEVA-XC12 is well-suited for the design of LTE-Advanced Pro Evolution, enhanced Mobile Broadband (eMBB), Licensed Assisted Access (LAA), MulteFire carrier aggregation and LWA (LTE/Wi-Fi Aggregation), cellular V2X, Wi-Fi 802.11ax, WiGig 802.11ad, Fixed Wireless Access (FWA) and Virtual Reality (VR) systems.

The CEVA-XC12 comes with a new micro-architecture to meet very high frequency requirements and ultra-low power consumption – capable of operating at 1.8 GHz in 10 nm and 50% less power than its predecessor, the CEVA-XC4500. It offers massive computation capabilities to maintain a high bit-rate – equipped with quad-vector processor engines approaching 1 tera operations per second (TOPs) performance. New and unique high-precision arithmetic achieves optimal resolution with up to 256×256 dimension matrix processing. The IP supports new specialized instructions to boost all baseband processing components including innovative support for advanced 256 and 1024 QAM demodulation. New core streaming interfaces allow ultra-low latency transfers between cores or accelerators and a new control plane for massive-user management and for multi-RAT (Radio Access Technology) systems incorporates a Scalar Processing Unit with a CoreMark/MHz score of 4.4 designed to handle huge number of users required for LTE MTC and 5G IoT.
