3.1.4 Memory interface
Memory access is provided by a MultiPort Memory Controller (MPMC) and a Static
Memory Controller (SSMC) located in the ARM926EJ-S PXP Development Chip. One
or two expansion memory boards can be added to increase the amount of flash, SRAM,
and SDRAM memory.
Memory (or memory-mapped peripherals) can also be accessed on an optional Logic
Tile or PCI card.
Note
The memory at
0x00000000
and
0x34000000
at boot time is determined by the boot select
switches and the remap signals (see Memory aliasing at reset on page 3-27). The region
at
0x80000000
0xFFFFFFFF
is recommended for accesses to a Logic Tile. PCI cards must
be initialized before use (see PCI configuration on page 4-79).
