APB register access, AHB bursts, AXI channels, AXI-Lite, AXI-Stream, bridges, interconnect, and integration pitfalls.
Try the section checkpoint, then review the Q&A
AMBA interfaces cover different contracts: APB's setup/access transfers, AHB's pipelined bus model, and AXI's independent channels and outstanding transactions.
Illustrative review: W arrived before AW, which is legal AXI4 traffic, but a converter neither buffered the early data nor backpressured it. The defect was the converter's admission contract, not channel arrival order.
