6254C–ATARM–22-Jan-10
AT91SAM9XE128/256/512 Preliminary
7.2
Bus Matrix
6-layer Matrix, handling requests from 6 masters
Programmable Arbitration strategy
– Fixed-priority Arbitration
– Round-Robin Arbitration, either with no default master, last accessed default master
or fixed default master
Burst Management
– Breaking with Slot Cycle Limit Support
– Undefined Burst Length Support
One Address Decoder provided per Master
– Three different slaves may be assigned to each decoded memory area: one for
internal ROM boot, one for internal flash boot, one after remap
Boot Mode Select
– Non-volatile Boot Memory can be internal ROM or internal Flash
– Selection is made by General purpose NVM bit sampled at reset
Remap Command
– Allows Remapping of an Internal SRAM in Place of the Boot Non-Volatile Memory
(ROM or Flash)
– Allows Handling of Dynamic Exception Vectors
7.2.1
Matrix Masters
The Bus Matrix of the AT91SAM9XE128/256/512 manages six Masters, thus each master can
perform an access concurrently with others, depending on whether the slave it accesses is
available.
Each Master has its own decoder, which can be defined specifically for each master. In order to
simplify the addressing, all the masters have the same decodings.
7.2.2
Matrix Slaves
Each Slave has its own arbiter, thus allowing a different arbitration per Slave to be programmed.
