  • Serial communications controller for transfer of successive data frames with storage of supplemental data and word counts
    Patent number: 5151999
    Abstract: A serial communications controller, adapted for transfer of data to memory in a direct memory access interrupt, generates a status word for each frame of data. To allow for uninterrupted transfer of data to memory from frame to frame, the status words are stored in a FIFO along with word counts corresponding to the frames to allow for subsequent identification of the addresses to which the data frames are assigned.
    Type: Grant
    Filed: November 3, 1989
    Date of Patent: September 29, 1992
    Assignee: Wang Laboratories, Inc.
    Inventors: Teresa Marzucco, John Korpusik, Patricia A. Martin
  • Serial communications controller with FIFO register for storing supplemental data and counter for counting number of words within each transferred frame
    Patent number: 4942515
    Abstract: A single chip serial communications controller, adapted for transfer of data to memory in a direct memory access interrupt, generates a status word for each frame of data. To allow for uninterrupted transfer of data to memory from frame to frame, the status words are stored in a FIFO along with word counts corresponding to the frames to allow for subsequent identification of the addresses to which the data frames are assigned. The FIFO is incremented at the end of each frame and decremented as each status word is read by a CPU.
