Simulink Coder - Customizing stateflow generated code

Dear Techies, I am intended to generate code from my Stateflow models. I am using Unit delay blocks to represent variables of static type outside the stateflow chart.Because of this generated code is not optimized.
So Is there any way I can represent static type variables within the stateflow? That is implementing the unit delay functionlity inside the stateflow chart. (Using DSM blocks is not allowed as per our guidelines.)
regards, Joseph

Unit delay block just have a state variables which stores the previous value of input.
Similarly in Stateflow, you can use a local variable to store the previous value of data. You can use one parallel state with priority-1 which handles all your normal operation and another parallel state with priority-2 which saves the data to previous local variable.
See the Pseudocode below (unfortunately I don't have access to any image hosting website. Thats why I am unable to post any image to explain implementation in stateflow)
/* Parallel state-1 for Operation using previous value */
Out = data + data_prev;
/* Parallel state-2 for saving previous value */
data_prev = data;
But, I can not understand how a unit delay block is affecting your code optimization.
