It is an interface between ARM core and DSP core. You can use the bridge
to load firmware into DSP, control its execution and allow data communication,
e.g. MP3 stream input and PCM data output.

you need separate compiler (i.e. CCS) to build code for DSP (i.e. CODECs). DSP 
will have C5000 or C6000 core (C64x in case of 3530) and not ARM core.

ARM gcc is used only to build the Linux DSPbridge driver.
