2.2 Memory Map Summary

Table 2-3shows the memory map address ranges of the device. Table 2-3depicts the expanded map of the Configuration Space (0x01C0 0000 through 0x01FF FFFF). The device has multiple on-chip memories associated with its processor and various subsystems. To help simplify software development a unified memory map is used where possible to maintain a consistent view of device resources across all bus masters. The bus masters are the ARM, EDMA, USB, and VPSS.
