I have made little addition into your code in order to display time in ms on the graph using TICKS variable:

Code:


EXPORT HAT()
BEGIN 

  LOCAL T := TICKS;

  ...

  T := TICKS - T;
  TEXTOUT_P(T,0,0,0,#FF0000);

  FREEZE;
END;

Testing it with latest public beta, it returns around 350ms. Calling program with TIME(HAT) returns usually the same... And this is far better result, assuming latest beta is true emulator and TICKS is indeed precise under 1 ms. What exactly firmware revision is on your devices?

Still reading PPL manual (testing samples occasionally), much better results (in theory) may be accomplished if it is possible to draw in additional graphics variable (G1-G9) and then simply swap with G0. This way (in theory) is avoided slow display transfer during computation.

EDIT: I have manage to find reference regarding copying graph data and that is BLIT. If used graphic variable specified to G1, copying complete content to G0 is simply BLIT(G1). What results are now on actual devices?
