The simplest case:

I don't think that will pick up the case where the required output is on
the line before Processor, but thanks, M

{
  if(NR == 1)
  {
    prev = $0
  }
  else
  {
    if($0 ~ /Processor/)

      print prev

    prev = $0

I didn't catch the original post, but based on your comment, it sounds like you want to do record based processing, where the content of the prior line is processed in some one when some condition on the current line is met? If so, this may help you out. I'm leaving out the awk invocation itself, you can put this in a file and use the '-f filename' option or put it on the command line between single quotes:
