Apparatus and methods to efficiently process packet data are disclosed. In one embodiment, a microcode engine designed to efficiently parse packet data may use instructions that are tailored to parse packet data fields of a data packet having nested protocols. The microcode engine design and the instruction set may enable highly efficient packet processing while preserving flexibility as to the packet protocols that can be processed. The implementation can be both specific to a packet processing task while allowing reprogramming to perform a different specific task simply by changing the instructions. The microcode engine may execute instructions in a single clock cycle or in a pipelined configuration to generate appropriately modified packet data. The microcode engine may operate in lock step with received packet data.

Microcode engine for packet processing

A bridge comprises an InfiniBand channel adapter, a fiber channel adapter, a command path, and a data path. The command path is coupled to the InfiniBand channel adapter and the fiber channel adapter; and the command path is operable to receive commands from a first of the InfiniBand and fiber channel adapters, to process the received commands, and to transmit the processed command to the other of the InfiniBand and fiber channel adapters. The data path is coupled to the InfiniBand adapter and fiber channel adapter, and is operable to transfer data from the first of the InfiniBand and fiber channel adapters to the other of InfiniBand and fiber channel adapters.

Infiniband/fibre channel bridge architecture

A bridge comprises an InfiniBand port, a fiber channel port, a cut-through data path coupled to the InfiniBand port and fiber channel port comprising a data buffer path operable to store data, and a message control path operable to decode and encode message headers.
