title: OMAP Dynamic Memory Manager (DMM)

description:
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.
