摘要:
A system and method of providing an embedded controller network communication protocol, for controlling communications between a central controller and a plurality of active embedded controllers, wherein a first data transmission token (T2) is passed, under control of the central controller, from the central controller to an active embedded controller, back to the central controller, and then sequentially from the central controller to and from each coupled active embedded controller. Any active embedded controller may return data to the central controller only appended to the first token. A second data transmission token (T1) addressed to one active embedded controller is broadcast from the central controller to all of the active embedded controllers, with a data stream to be transmitted from the central controller to the addressed active embedded controller appended to the second data transmission token (T1). The first data transmission token (T2) is inserted between data bytes of a data stream appended to the second data transmission token to provide full duplex communication.
摘要:
A scheduling method and apparatus for use by a processor that controls storage devices of a data storage system is presented. The method allocates processing time between I/O operations and background operations for predetermined time slots based on an indicator of processor workload.
