Hi,
I was wondering what the DSPBRIDGE does?
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.
I've used TI code composer studio in the past, and was wondering if that
compiler is required to compile programs for the DSP available on the TI
OMAP 3530.
In terms of compiler infrastructure, can the current arm gcc tools be
used for both the arm core and the dsp part? Or do you need to use TI
CCS for the dsp part?
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.
Best regards,
Elvis
