CEVA has introduced a programmable DSP architecture supporting communication standards for cellular, Wi-Fi, digital TV and white space radio.
The CEVA-XC4000 offers a big jump in performance over the silicon IP firm's XC323 DSP for LTE-A processing, while consuming less power, said CEVA.
“Incorporating new power management techniques, we were able to dramatically reduce the power consumption for high-performance software-based processing, paving the way for modem developers to exploit the flexibility, reusability and time-to-market advantages that a software-defined approach brings,” said Gideon Wertheizer, CEO of CEVA.
The embedded wireless platform includes the firm's second generation Power Scaling Unit (PSU 2.0) which dynamically supports clock and voltage scaling with fine granularity within the processor, memories, buses and system resources.
The DSP platform also uses Tightly Coupled Extensions (TCE) to deliver inter-connected power-optimized coprocessors and interfaces for the implementation of critical PHY functions, further reducing power consumption.
A rebalanced pipeline with low-level module isolation is also highly optimized for power.
The architecture offers uncompromising modem quality using two distinct inter-mixable high-precision instruction sets, supporting the most advanced 4x4 and 8x8 MIMO algorithms.
CEVA has also announced reference architectures targeting communication standards, including LTE-A Rel-10 and Wi-Fi 802.11ac supporting up to 1.7Gbit/s, in collaboration with CEVA-XCnet partners mimoOn and Antcor.
These reference architectures are complemented with highly optimised software libraries for LTE-A and Wi-Fi.
