Bus Matrix
Matrix Masters
Matrix Slaves
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.
Table 7-1.
Each Slave has its own arbiter, thus allowing a different arbitration per Slave to be programmed.
Table 7-2.

• 6-layer Matrix, handling requests from 6 masters
• Programmable Arbitration strategy
• Burst Management
• One Address Decoder provided per Master
• Boot Mode Select
• Remap Command
– Fixed-priority Arbitration
– Round-Robin Arbitration, either with no default master, last accessed default master
– Breaking with Slot Cycle Limit Support
– Undefined Burst Length Support
– Three different slaves may be assigned to each decoded memory area: one for

– Selection is made by General purpose NVM bit sampled at reset
– Allows Remapping of an Internal SRAM in Place of the Boot Non-Volatile Memory
– Allows Handling of Dynamic Exception Vectors
