Abstract
A fibre channel switch element with an integrated fabric controller on a single chip is provided. The fabric controller including a processor module that can control various switch element functions; a serlizer/de-serializer for converting parallel data to serial data for transmission; an on-chip peripheral bus that allows communication between plural components and the processor module; a processor local bus and an interrupt controller that provides interrupts to the processor module. The integrated fabric controller also includes a flash controller and an external memory controller; an Ethernet controller; a Universal Asynchronous Receiver Transmitter ('UART') module that performs serial to parallel conversion and vice-versa; an IC module that performs serial to parallel and parallel to serial conversion; a general-purpose input/output interface; a real time clock module; an interrupt controller that can receive interrupts inputs from both internal and external sources; and a bridge to an internal PCI bus.
