" summary

Claims that RISC-V plus Cadence HiFi DSP yield lower-cost, battery-optimized TWS SoCs with concrete architectures: examples show a 4-stage RISC-V AP and smaller RISC-V baseband controller plus HiFi One for always-on tasks and HiFi 4/5 for ML noise cancellation. Cites LC3 codec support, Bluetooth LE Audio dual-mode transition, over 155 HiFi licensees and 1.5 billion devices shipped annually. Provides toolchain and partner integrations for Bluetooth stacks and codec/voice front ends, and shows core allocation that saves power while enabling ANC and keyword spotting.
