Abstract

The invention provides an intellectual property core of optical fiber channel, which pertains to the field of computer memory technology, resolves the imperfection of the function of the current intellectual property core, and realizes the protocol process function of FC-1 layer and the partial FC-2 layer of fiber channel. The invention comprises a 8b or 10 b decoder, a 8b or 10b coder, receiver state machine, a sending state machine, a fiber channel port state machine, a frame-receiving engine, a frame-sending engine, a frame-sending buffer area, a stream control module, configuration and a statistical module between buffer areas. The invention provides frame level user logical interface, adopts asynchronous FIFO queue as a frame-receiving buffer area and a frame sending buffer area, and provides perfect configuration and statistical function, thus improving the coordination capability of software and hardware.

Description

technical field [0001] The invention belongs to the technical field of computer storage, and in particular relates to an intellectual property core for realizing the protocol processing functions of the fiber channel FC-1 layer and part of the FC-2 layer. Background technique [0002] Fiber Channel (FC) is a serial data interface protocol formulated by the American National Standards Committee ANSI X3T11 group, which has an open architecture and low-latency, high-bandwidth and long-distance transmission characteristics. Fiber Channel combines high-speed and reliable channel technology with flexible and scalable network technology, supports SCSI (Small Computer Systems Interface, small computer system interface), IP (Internet Protocol, Internet Protocol) and other upper-layer data transmission protocols, and can realize large-capacity, High speed, high reliability and efficient information transmission. [0003] The current Fiber Channel protocol processing is done by a dedi...
