Matrix Masters
Matrix Slaves
AT91SAM9263 Preliminary
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.
The LCD Controller, the DMA Controller, the USB OTG and the USB Host have a user interface
mapped as a slave on the Matrix. They share the same layer, as programming them does not
require a high bandwidth.
