OMAP591x: Tuning the System Memory Requirements of DSP/BIOS Link

The DSP/BIOS™ Link software has been designed to implement inter-processor communication between a host device and a DSP. For the case of OMAP591x devices, the default configuration of the DSP/BIOS Link software requires that 2MB of system memory is reserved for exclusive use by DSP/BIOS Link. The intention was to provide developers using DSP/BIOS Link plenty of memory to begin with and enable them to tune the system memory requirements per their specific needs. This application report discusses how to tune the system memory reserved for DSP/BIOS Link with regard to the needs of the application.
