The host controller includes a plurality of functional modules interconnected to manage transfer of data between a host bus and a root hub configured to communicate with one or more USB device endpoints on the bus. The plurality of functional modules comprises a DMA engine to transfer one or more data payloads between the host bus and the root hub, a transfer manager configured to determine what control data and/or data payloads should be transferred, and a scheduler to schedule actions performed by the transfer manager. A plurality of control memories, each associated with one or more of the functional modules, store state and/or data information fields accessible by its one or more associated functional modules. The plurality of control memories are distinct and independently accessible from one another."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-port context-based host controller","description":"A host controller for a bus is disclosed.
