High performance DSP designed for advanced sound-processing

The CEVA-X2 is an advanced DSP optimized for intensive sound processing applications. It has been specifically designed to tackle multi-microphone speech processing use-cases, high quality audio playback and post-processing, and embedded sound neural network implementations.

The CEVA-X2 is a combined DSP/controller based on a VLIW/SIMD architecture with a 10-stage pipeline, operating at 2GHz in typical conditions of a 16nm process.

Other key features include:

4.5 CoreMark/MHz score,
dual 32×32 MAC operations per cycle,
quad 16×16 MAC operations per cycle,
64-bit SIMD fixed-point operations,
Up to two IEEE single-precision floating-point units operating in parallel.
The processor includes two Scalar Processing Units (SPUs), which support 8/16/32/64-bit data types for arithmetic and logic operations. It supports both static branch prediction and optional dynamic branch prediction, and offers both supervisor and user modes.

At a system level, the CEVA-X2 includes a 2-way or 4-way set-associative data cache with write-through and write-back policies, as well as hardware and software pre-fetch capabilities.

Data traffic is managed by the CEVA-X2 optional CEVA-Connect mechanism, which ensures intelligent scheduling for high Quality of Service (QoS) and low latency data transfer tasks and minimizes CEVA-X2 processor load.

CEVA-X2 supports your audio/voice/speech software needs using the extensive CEVA Sound Library, CEVA Neural Network Library, CEVA’s ClearVox Voice processing software package, and a vast ecosystem partner offerings of software solutions for any sound application.
