PSI-L is a packet based protocol used to transfer data between several device modules. Еach transaction is routed based on thread ID value instead of physical address. All PSI-L interfaces are point to point direct connections to DMSS0. All switching functions among the PSI-L based interfaces are done inside DMSS0.
The PSI-L also has an event interface referred to as ETL, which is purely used to transfer event information.
