Masters to Slaves Access
In most cases, all the masters can access all the slaves. However, some paths do not make
sense, for example, allowing access from the Ethernet MAC to the Internal Peripherals. Thus,
these paths are forbidden or simply not wired, and are shown as “-” in
The Peripheral DMA Controller handles transfer requests from the channel according to the fol-
lowing priorities (low to high priorities):
OHCI USB
Controller
• Acts as one Matrix Master
• Allows data transfers between a peripheral and memory without any intervention of the
• Next Pointer support, removes heavy real-time constraints on buffer management.
• Twenty channels
