Abstract

A method of designing a reprogrammable control sequencer is described. The invention uses a reprogrammable logic macro for the sequencers. The designer would create personalization code for each reprogrammable logic macro that would be written into each one before run time. Therefore, in the case of a sequencer error, it would be possible for the designer to develop new personalization code for any sequencer that uses the reprogrammable logic macro. The new personalization code would then be tried in the lab.

Reprogrammable Logic Macros

      A method of designing a reprogrammable control sequencer is
described.  The invention uses a reprogrammable logic macro for the
sequencers.  The designer would create personalization code for each
reprogrammable logic macro that would be written into each one before
run time.  Therefore, in the case of a sequencer error, it would be
possible for the designer to develop new personalization code for any
sequencer that uses the reprogrammable logic macro.  The new
personalization code would then be tried in the lab.

      The invention uses a reprogrammable logic macro for the
sequencers.  The designer would create personalization code for each
reprogrammable logic macro that would be written into each one before
run time.  Therefore, in the case of a sequencer error, it would be
possible for the designer to develop new personalization code for any
sequencer that uses the reprogrammable logic macro.  The new
personalization code would then be tried in the lab.

      Data flow would continue to be fixed as well as control logic
that can be exhaustively tested.  Basically, critical sequencers
would be the ones using reprogrammable logic macros.

      There are several different technologies available to build the
reprogrammable logic macros in.  Ultra violet and electrically
erasable technologies could be used, but would require module removal
to reprogram.  A latch based logic array would allow a support
processor t...
