SRAM Memory Map

Like the Peripheral Bus modules, the SRAM resides on a slave port of the AXBS, and therefore has a

movable base address on a 512MByte boundary. However, unlike the Peripheral Bus, the SRAM is

“mirrored” in the 512MByte space on a 32KB boundary. This gives us the following memory map for the

SRAM:
