Overview
Efficiently supports front-end audio processing like beamforming and noise reduction, as well as neural network-assisted speech recognition (ASR) processing.
The Cadence® Tensilica® HiFi 3z DSP raises the performance and energy efficiency over the HiFi 3 DSP when executing complex algorithms. Target applications include mobile, home entertainment, and automotive. As audio requirements for everything from smartphones to home stereo receivers to multi-speaker automotive configurations are being driven by advanced post-processing, the HiFi 3z DSP provides the right level of performance or such tasks while keeping the energy consumption at the lowest level.
