All the peripherals should use the L1 Memory System address alias(Multiprocessor space) to access the L1 Memory.

For example, if the source and the destination buffers of a MDMA are located in L1 Memory, its equivalent System address alias has to be given while configuring the DMA registers for proper operation.

The above table provides the L1 Memory Multiprocessor space alias map. Note that SHARC+ Code execution is not possible from this space.

There are two ports S1 and S2 , and the data can be accessed via any port.
