Abstract
An application specific circuit for acting as an interface between a data processing system and a high speed data channel. A single integrated circuit includes an interface circuit for transferring data to and from a high speed data channel such as a fibre channel that transfers information in frames according to specific protocols. A frame processing circuit receives and transmits data frames according to the protocol and processes incoming data frames to facilitate subsequent handling. A sequence management circuit transfers data frames to and from a local memory system. When data frames are received out of order, the sequence management circuit provides a mechanism for establishing the appropriate order. The sequence management circuitry initially includes circuitry for transferring data between the local memory system and a data processing system. Both the local memory system and the data processing system are external to the application specific integrated circuit.
