Journey from Closed to Open:

Lessons Learned from Open

Sourcing Sound Open Firmware

更多

Sound Open Firmware (SOF) is a permissive licensed open source audio DSP firmware and SDK that provides infrastructure and tools for audio DSP developers.

This presentation will tell the story of how Intel took a historically closed source firmware with a proprietary SDK and created an open source firmware with opensource SDK. It will also describe the technical and non-technical challenges that had to be overcome in releasing open source audio firmware and creating a free SDK.

Finally, the presentation will provide technical information about architecture, tooling and how to get involved.

Mission

1.Inspire others to open source firmware.

2.Show how firmware can be open sourced.

3.Discuss common challenges open sourcing firmware

and how to overcome them.

4.Introduce Sound Open Firmware (SOF) architecture.
