Preliminary data sheet
6.5 Multi-Port Memory Controller (MPMC)
The multi-port memory controller supports the interface to different memory types, for
example:
This module has the following features:
•

•
– Interrupts generated after completion of error correction task with three interrupt
– Error correction statistics distributed to ARM using interrupt scheme.
– Interface is compatible with the ARM External Bus Interface (EBI).
SDRAM
Low-power SDRAM
Static memory interface
Dynamic memory interface support including SDRAM, JEDEC low-power SDRAM.
Address line supporting up to 128 MB (two 64Mx8 devices connected to a single chip
select) of dynamic memory.
The MPMC has two AHB interfaces:
a. an interface for accessing external memory.
b. a separate control interface to program the MPMC. This enables the MPMC
Low transaction latency.
Read and write buffers to reduce latency and to improve performance, particularly for
un-cached processors.
Static memory features include:
– asynchronous page mode read
– programmable wait states
– bus turnaround delay
– output enable, and write enable delays
– extended wait
One chip select for synchronous memory and two chip selects for static memory
devices.
Power-saving modes.
Dynamic memory self-refresh mode supported.
Controller support for 2 k, 4 k, and 8 k row address synchronous memory parts.
Support for all AHB burst types.
Little and big-endian support.
Support for the External Bus Interface (EBI) that enables the memory controller pads
to be shared.
registers.
registers to be situated in memory with other system peripheral registers.
