Further developments

Another possible solution is to use the eDMA module to access the memory with the

minimal intervention from the core.

The eDMA module is a highly programmable data transfer engine and it is used to transfer

data from crossbar switch to IPS bus.

The crossbar switch connects bus musters and bus slaves using a hardware interconnect

matrix. DMA is Xbar master and RAM controller is Xbar slave.

The PRAM controller (PRAM CTL) acts as an interface between the system bus and the

dedicated RAM array interface.
