Overview

The CEVA-XC4500 DSP core is the fourth generation of the widely licensed CEVA-XC architecture. Optimized for advanced communication applications, especially high-performance wireless infrastructure equipment, it features a combination of VLIW (Very Long Instruction Word) and vector engines that enhance typical DSP capabilities with advanced scalar and floating-point vector processing.

Based on the architecture of the CEVA-XC4000 DSP family, the CEVA-XC4500 DSP core has two advanced vector-processing units supporting both fixed-point and floating-point instruction sets. Built-in support for traffic management and dynamic scheduling provides efficient data processing within basestations, remote radio heads, and backhaul equipment. Supported by full hardware cache coherency, multiple cores can be deployed to scale the amount of traffic to be handled, from picocells to macrocells to Cloud-RAN, with no software overhead.

With its innovative programmable approach, the CEVA-XC4500 offers the high flexibility needed to support a large number of wireless standards on a single programmable platform, thereby significantly reducing development cost and time-to-market.
