By default the ARM has access to most on and off chip memory areas, including the DSP Internal memories, EMIFA, DDR2, and the additional 128K byte on chip shared SRAM. Likewise almost all of the on chip peripherals are accessible to the ARM by default.
To improve security and/or robustness, the device has extensive memory and peripheral protection units which can be configured to limit access rights to the various on/off chip resources to specific hosts; including the ARM as well as other master peripherals. This allows the system tasks to be partitioned between the ARM and DSP as best suites the particular application; while enhancing the overall robustness of the solution
See Table 3-4 for a detailed top level device memory map that includes the ARM memory space.
