The CEVA-X2™ is an advanced DSP optimized for intensive sound processing applications. It has been specifically designed to tackle multi-microphone speech processing...
Overview
The CEVA “smart and connected” development platform is the ultimate tool for algorithm and system designers who want to develop and prototype audio and sensing solutions using real-time, full-speed silicon.
The platform is built around a 500 MHz audio-and-sensing CEVA DSP chip fabricated using the IoT-centric SMIC 55 nm LP process, which also incorporates a rich integrated set of peripherals and interfaces. A multi-microphone daughter board with 13 microphones complements the high-speed silicon for development of sound‑pickup algorithms (for example, far-field voice pickup, beamforming, acoustic echo cancellation, de-reverberation and so on).
Using the included DSP RTOS, the platform provides ample processing power for multiple functions running concurrently. This enables prototyping of real-world use cases, such as always-on sensing, local intelligence, and high-throughput multi-microphone processing, all of which are supported by the “smart and connected” platform.
Because low-power signal processing is a key element in smart IoT device differentiation, the platform also provides real-time power measurement and display, which enables developers to optimize and power-tune their DSP firmware.
