TOOLS

Includes tool chain, debugger, emulator, and firmware image creation tools

Proprietary compilers and emulators available

Written in C with some architecture specific assembler and does not link to any external dependencies

Tools to convert firmware file formats and help with debugging running firmware images

Used to build the firmware binaries. Can also use other compilers/tool chains to build firmware

Helps trace and debug driver and DSP firmware code simultaneously

Registers the DSP and firmware as a kernel audio device and exposes various hardware capabilities, and loads any topology data
