Table 7-1.
The Bus Matrix of the AT91SAM9R64/RL64 product manages 6 slaves. Each slave has its own
arbiter, allowing a different arbitration per slave.
Table 7-2.
All the Masters can normally access all the Slaves. However, some paths do not make sense,
for example allowing access from the USB Device High speed DMA to the Internal Peripherals.
Thus, these paths are forbidden or simply not wired, and shown as “-” in the following table.
The Peripheral DMA Controller handles transfer requests from the channel according to the fol-
lowing priorities (Low to High priorities):
Master 3
Master 4
Master 5
Slave 0
Slave 1
Slave 2
Slave 3
Slave 4
Slave 5
• Acting as one AHB Bus Matrix Master
• Allows data transfers from/to peripheral to/from any memory space without any intervention
• Next Pointer support, prevents strong real-time constraints on buffer management.
