  • System for scheduling periodic events having varying rates by cascading a plurality of overlapping linked list data structure
    Patent number: 5933655
    Abstract: A system for scheduling periodic events having varying rates. The system uses a linked list type data structure and an array to schedule the plurality of events having varying rates. In a preferred embodiment of the invention, data items are scheduled for transfer during a plurality of data transfer intervals. The linked list type data structure is traversed for each data transfer interval to collect the data items requiring transfer.

  • System using a variable timer to optimally adjust issuing a start data collection signal at near the beginning of data transmission signal
    Patent number: 5862411
    Abstract: 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.

  • Receive packet pre-parsing by a DMA controller
    Patent number: 5809334
    Abstract: 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.
