The device implements a system interconnect using TI’s Common Bus Architecture (CBA), composed of the VBUSM and VBUSP protocols.
The system is based on a multi-layered interconnect approach designed to meet high-performance system requirements. The core interconnect structure consists of a full crossbar implementation, where every initiator has an independent communication path with every target. In other words, any initiator can access any target on the interconnect while another initiator can access a different target simultaneously without any contention,such that, transactions from each initiator has access to full interconnect bandwidth. Arbitration will happen at the target end point (when the same target is accessed by two or more initiators) and at the initiator point when request is sent back. Targets cannot generate read/write requests directly. However, they can respond to these requests by generating error events (as defined by the CBA protocol), interrupts, and DMA requests.
The device interconnect is partitioned into the following sections:
