    摘要: A processor-based control system including a host processor, a data receiver device, a system memory, and an intelligent DMA controller. The DMA controller includes a pre-parsing section. The pre-parsing section interrogating a received data packet to determine whether the received data packet contains an error, is valid, is a null packet or whether the host processor must be contacted.

    摘要: A controller based network, where data from a plurality of nodes is placed onto the network in a scheduled predetermined order during a network update interval. The data transmitted onto the network being collected following the issuance of a data collection start signal issued in accordance with a timer, whereby the issuance of the data collection start signal can be varied within the network update interval. The collected data being transmitted onto the network upon the issuance of a data transmission signal.
