Fully Integrated Voice-over-Packet (VoP) Application Platform

The CEVA-VoP platform is targeted at residential and consumer markets. Based on Xpert-TeakLite-II, the platform is a complete hardware and software solution that can be deployed as a subsystem in an integrated networking-and-VoP SoC. The platform integrates CEVA's programmable TeakLite-II DSP core, with added hardware peripherals capable of handling multiple, simultaneous, packet-voice channels on a single core. The solution includes a fully integrated VoIP software suite, including speech compression and decompression, echo cancellation, telephony functions, and signaling/networking. The incorporated software is open, allowing design licensees to add proprietary algorithms and broaden the use of the design to other markets or applications.

CEVA-VoP Platform

The CEVA-VoP solution comprises four key elements:

Programmable DSP - the 200MHz CEVA-TeakLite-II is a small die size, low power DSP core

DSP Subsystem - a highly integrated, compact Xpert-TeakLite-II subsystem, incorporating a cache memory architecture to reduce cost, with small memory footprint and an AHB/APB bridges for easy system integration.

VoIP Software - the solution is based on an open, programmable platform and contains a complete suite of voice, telephony, RTP, and networking modules, integrated with an application framework and scheduler.

Complete development tools chain - complete software development tool suite and system boards for customer support from initial design to final tapeout.
