Licensor of intellectual property and DSP cores Ceva has introduced the Ceva-XC4500 DSP, a vector floating-point digital signal processor (DSP) designed for advanced mobile infrastructure applications targeting macrocells, small cells, cloud-RAN, digital front-end and backhaul. The device provides up to 1.3GHz performance on 28nm, vector DSP engine for baseband applications, supports fixed point and floating point (IEEE compliant) ISA on full vectors and enables software-defined architecture with a mix of optimised hardware engines for DSP offloading. The DSP also incorporates advanced data cache including hardware cache coherency via ARM Amba 4 ACE and Advanced System Interconnect, which uses a mix of ARM AMBA 4 compliant buses and fast interconnect (FIC) buses. It also features automated data traffic management offering fully parallel hardware acceleration management.
The Ceva-XC4500 DSP architecture is supported by Ceva-Toolbox, a software development environment, incorporating Vec-C compiler technology for advanced vector processors, enabling the architecture to be programmed in C. The integrated simulator and profiler provide accurate modelling of the entire system including caches, DMA controllers, interfaces and tightly coupled extensions. In addition, Ceva-Toolbox includes a set of LTE/LTE-Advanced eNodeB libraries, which complements the existing library suite for Wi-Fi, TD-SCDMA, WCDMA, and HSPA+. This DSP is available for licensing and is already in design with a Tier-1 mobile infrastructure vendor.
