Study path

Marvell-style ASIC interview preparation

Follow packets and descriptors through links, DMA rings, FIFOs, and arbiters. State framing, credit, ordering, ownership, and timeout rules before writing the implementation or scoreboard.

Use directed corner cases plus traffic stress to prove no packet, credit, or completion is duplicated or lost. These independent exercises do not describe Marvell's official interview process.
