Bus Matrix
Matrix Masters
Matrix Slaves
AT91SAM9263
The Bus Matrix of the AT91SAM9263 manages nine masters, thus each master can perform an
access concurrently with others to an available slave peripheral or memory.
Each master has its own decoder, which is defined specifically for each master.
Table 7-1.
The Bus Matrix of the AT91SAM9263 manages eight slaves. Each slave has its own arbiter,
thus allowing to program a different arbitration per slave.

• 9-layer Matrix, handling requests from 9 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
– Non-volatile Boot Memory can be internal or external
– Selection is made by BMS pin sampled at reset
– Allows Remapping of an Internal SRAM in Place of the Boot Non-Volatile Memory
– Allows Handling of Dynamic Exception Vectors
or fixed default master
internal boot, one for external boot, one after remap
