Sound Open Firmware is an open source audio DSP firmware and SDK intended to provide a generic audio firmware infrastructure and development tools to the community. The firmware is BSD licensed and is platform and architecture independent. The SDK is also open source and provides a toolchain, debugger, emulator and firmware image creation tools.
Sound Open supports the Cadence HiFi DSP used in the Intel Atom E3800 processor on the MinnowBoard MAX. The standard Sound Open SDK is a command-line development environment based on GCC. An optimizing C compiler and GUI IDE optimzed for DSP audio development will soon be available from Cadence.
