Memory Map
The lower 2 Gbytes of the address space is allocated to ROM and expansion space; the upper Gbyte of
address space is allocated to DRAM. The remaining Gbyte, less 4K for internal registers, is not accessible
in the CL-PS7110. Program the MMU in the CL-PS7110 to generate an abort exception for access to this
area.
Internal peripherals are addressed through a set of internal memory locations, from hexadecimal address
8000.000–8000.0FFF, are known as the internal registers in the CL-PS7110.
Table 3-1
shows the mapping of the 4-Gbyte address range of the ARM710A microprocessor in the
CL-PS7110.
