Subject: Fastest way to reverse-process a string?

In a ruby program I'm writing, I want to parse a string in reverse and
feed each of its individual characters through a state machine.

A "hammer and tongs" solution looks like this:

  string.reverse.split(//).each {
    |ch|
    feedIntoStateMachine(ch)
  }

However, this seems rather inefficient.  Does anyone know of a faster
algorithm for this in ruby?

Thanks in advance.
