8.1.1. Features of the System Interconnect
The system interconnect supports high-throughput peripheral devices. The system interconnect has the following characteristics:
- Byte oriented address handling
- Data bus width up to 128 bits
- Arm* TrustZone* -compliant firewall and security support, with additional security features configurable per master
- Programmable quality-of-service (QoS) optimization
- Dedicated SDRAM L3 interconnect, providing access and scheduling for the hard memory controller in the FPGA portion of the SoC device
- On-chip debug and tracing capabilities
- Multiple independent L4 buses with independent clock domains and protocols
The L4 buses are each connected to a master in the main L3 interconnect for control and status register access. Each L4 bus is 32 bits wide and is connected to multiple slaves. The L4 buses also provide a low- to mid-level tier of the system interconnect for lower-bandwidth slave peripherals. Each L4 bus is 32 bits wide and operates in a separate clock domain.
