Matrix Slaves
Masters to Slaves Access
Masters to Slaves Access
Each Slave has its own arbiter, thus allowing a different arbitration per Slave to be programmed.
Table 7-2.
All the Masters can normally access all the Slaves. However, some paths do not make sense,
such as allowing access from the Ethernet MAC to the internal peripherals.
Thus, these paths are forbidden or simply not wired, and shown as “–” in the following table.

Slave 5
• Acting as one Matrix Master
• Allows data transfers from/to peripheral to/from any memory space without any intervention
• Next Pointer Support, forbids strong real-time constraints on buffer management.
• Twenty-four channels
Master
