2.2.4 AXI4 master interfaces
The AMBA® 4 protocol defines the AXI4 protocol that supports high-performance, high-frequency system designs.
Depending on configuration, the CCI-550 includes:
- Between one and six AXI4 master interfaces for connecting to memory.
- Between one and three AXI4 master interfaces for connecting to the rest of the
The primary difference between memory and system interfaces is the definition
in the memory map. You can configure memory interfaces to be interleaved across the
memory region, for example striping, to enable higher utilization of memory. See the
AMBA® AXI and
ACE Protocol Specification, AXI3, AXI4, and AXI4-Lite ACE and ACE-Lite for
more information about AXI4.
