-        input data p.i_data is read (only), is processed and goes into an
-        intermediate result store [process()].  this is updated combinatorially.
-
-        in a non-stall condition, the intermediate result will go into the
-        output (update_output).  however if ever there is a stall, it goes
-        into r_data instead [update_buffer()].
-
-        when the non-stall condition is released, r_data is the first
-        to be transferred to the output [flush_buffer()], and the stall
-        condition cleared.
-
-        on the next cycle (as long as stall is not raised again) the
-        input may begin to be processed and transferred directly to output.
