MIPI SoundWire Master Controller 1.1

Overview

The Total MIPI Soundwire IP Solution enables early adopters the fastest path to adoption of this new standard by offering a comprehensive IP package that includes the Verilog RTL source code validated for compliance with the standard, a comprehensive test environment & compliance suite for validation of the IP, a Soundwire hardware development kit for FPGA prototyping and interoperability testing, a Soundwire protocol analyzer and the complete Soundwire software stack.

The IP is fully configurable for the number of (options like endpoint, audio channels etc.) to meet a wide range of audio applications. Soundwire is suited for small, very cost-sensitive audio peripherals such as amplifiers and microphones.
