DSP Gateway can be used to communicate between the ARM core and the DSP. For example in case of OMAP 1710 there is an ARM926 core and a DSP, DSP gateway is used for communicating between them. In case for OMAPs like OMAP 730 etc the arch is little bit different i.e. ARM 926 is used as an application processor and on the DBB side there is ARM 7 and a DSP. -pharaoh.
