I'm trying to implement a method used by Mr. Jeff Miller in a Matlab training session entitled "Fixed Point Made Easy," and had a question regarding his use of look-up tables

My question is regarding the splitting of the sfix18 angle value into two numbers, one composed of the upper 9 bits the other composed of the lower 9 bits. Isn't the LUT_HIGH for angles =>pi, and the LUT_LOW for angles <pi so that only one LUT is being used at a time? I was also wondering what the workings of the HDL_Complex_Multiplier would look like. Thank you for your attention to my question.
