Abstract
A host system is provided with one or more host-fabric adapters installed therein for connecting to a switched fabric of a data network. The host-fabric adapter comprises a micro-controller subsystem configured to establish connections and support data transfers via the switched fabric, and a serial interface which provides an interface with the switched fabric. The micro-controller subsystem includes a Micro-Engine (ME) which executes a ME instruction to send source and destination addresses during a control cycle, and interface logic blocks which supply addressed data from designated sources to the Micro-Engine (ME) at the same time for execution of the ME instruction during a data cycle subsequent to the control cycle.
