The L3 interconnect allows the sharing of resources, such as peripherals and external or on-chip memories, between all the initiators of the platform. The L4 interconnects control access to the peripherals.
Transfers between initiators and targets across the platform are physically conditioned by the chip interconnect.
The L3 topology is driven by performance requirements, bus types, and clocking structure. Figure 7-1 shows the interconnect of the device and the main modules and subsystems in the platform. Arrows indicate the master-and-slave relationship, not data flow. Master-and-slave connectivity is shown in Table 7-1.

The L4 interconnect is a non-blocking peripheral interconnect that provides low-latency access to a large number of low-bandwidth, physically-dispersed target cores. The L4 can handle incoming traffic from up to four initiators and can distribute those communication requests to and collect related responses from up to 63 targets.
The device provides three interfaces with L3 interconnect for high-speed peripheral and standard peripheral.Figure 7-2 and Table 7-2 show the L4 bus architecture and memory-mapped peripherals.
