The dynamic memory manager (DMM) is a module located immediately in front of
|
|
the SDRAM controllers (called EMIFs on OMAP). DMM manages various aspects of
|
|
memory accesses such as priority generation amongst initiators, configuration
|
|
of SDRAM interleaving, optimizing transfer of 2D block objects, and provide
|
|
MMU-like page translation for initiators which need contiguous dma bus
|
|
addresses.
