Abstract: INTEGRATED DATA LINK CONTROLLER WITH      AUTONOMOUS LOGICAL ELEMENTS            ABSTRACT OF THE DISCLOSURE      A  single  chip  integrated  data  link  control  (IDLC) device provides full duplex data throughput and versatile protocol  adaptation  between  variably  configured  time channels on a high speed TDM digital link (e.g. T-1 or T-3 line) and a host data processing system. The device handles multiple  channels  of  mixed  voice  and  data  traffic concurrently, and thereby is suited for use in primary rate ISDN  (Integrated  Services  Digital  Network)  applications. Synchronous  and  asynchronous   sections  in  the  device respectively interface with the network and host system. Special purpose autonomous logic elements in the synchronous section form plural stage receive and transmit processing pipelines  between the network and host  interfaces.  Such pipelines perform OSI Layer 2 processing tasks on data in HDLC channels. Each autonomous element comprises one or more state  machine  circuits  having  functional  autonomy  and reduced  time  dependence  relative  to  other  elements.  A "resource manager"  element  (RSM)  and time  swap  (TS)  RAM memory  operate  to  dynamically  swap  states  of  pipeline elements  in  synchronism with  channel  time  slots  at  the network interface, whereby the pipeline stages operate as data buffering stages which perform multiple tasks during any slot. The device contains integrated memory queues in which   communication   data   and   channel   event   status information   are   stacked   for   asynchronous   transfer. Capacities  and  modes  of  operation  of  these  queues  are selected to minimize effects on chip size, throughput and cost, while minimizing critical time dependencies between the device and host system. Device elements provide first and  second  non-interfering  information  transfer  paths between the device and host system;  one for exchanges of control/status information between the device and host, and the   other   for   direct   memory   access   transfers   of communication data between the device and an external memory associated with the host.

Abstract: A plurality of thermal ink jet printheads, each with nozzles in a pre-diced nozzle face, obtained from sectioning of an etched channel wafer aligned and mated with a heating element containing wafer that have a patterned thick film layer sandwiched therebetween. The printhead nozzles and pre-diced nozzle face are produced in the channel wafer prior to the alignment and mating of the wafers by the combination of dicing a notch in the channel wafer through one end of a plurality of sets of etched channel grooves, forming the nozzles and the nozzle face in the channel wafer and photodelineating the thick film layer on the heating element wafer, so that when the wafers are mated, the delineated edge of the thick film layer becomes part of the nozzles without requiring the cutting of the thick film layer by a dicing blade. In one embodiment, the heating element wafer has a similar notch diced therein adjacent the delineated edge of the thick film layer prior to mating with the channel wafer. The two notches are confrontingly aligned and the mated wafers are sectioned into separate printheads by dicing through the aligned notches, so that the dicing blade is spaced from the printhead nozzle faces.
