説明
The DA14850 is Renesas’ next generation low power audio processor. The device combines Renesas Smart Codecs and PMIC devices to form a flexible, powerful chipset optimized for low power consumption and high-performance audio products. The DA14850 integrates an Arm® Cortex®-M33F application processor, a Tensilica® Fusion F1 DSP, and a rich set of peripherals and communication interfaces including USB 2.0 HS/FS.
The DA14850 features multi-core AI (artificial intelligence) capability. The device integrates a dedicated low-power NNP (neural network processor) technology to support VAD (voice activity detection), HWD (hot-word-detection), acoustic event detection (ex. glass breaking, police car siren, etc.), and audio scene detection (ex. restaurant, music, etc.) to offer Machine-Learning contexture awareness features. The Renesas Reality AI tool seamless works with the DA14850 application processor by Arm Cortex-M33 and Cadence Fusion F1 DSP processor. Renesas’ Reality AI tool comes with Renesas global support including AI model generation at highly compact code, design review, monitor tool, and many optional add-ons.
Renesas DA14850 processor enables many new applications including USB audio devices for communication, audio processor, as well as battery-powered portable applications for sound detection and hearing enhancement.
