MIPI SoundWire Peripheral IP
Design IP
Overview

SmartDV’s MIPI SoundWire Peripheral IP is a compact, power-efficient solution designed to connect audio peripherals to SoundWire-based masters in mobile, automotive, and consumer systems. Fully compliant with the MIPI SoundWire 1.3 specification, it enables synchronized, bidirectional audio data exchange with precise control and minimal wiring.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance. It supports key features such as device enumeration, interrupt generation, audio data transport, and dynamic frame configuration, ensuring reliable and scalable integration into a wide range of audio subsystems.

MIPI SoundWire Slave
Benefits
  • Comprehensive Peripheral Functionality – Implements complete SoundWire Peripheral behavior, including synchronization, command response, and data transport
  • Multi-Slave Integration – Supports up to 11 slave devices on a shared bus with independent configuration and operation
  • Configurable Architecture – Allows flexible setup of PDIs, command FIFOs, data lanes, and port memories to meet system requirements
