-// The function calculates the cross-correlation between two sequences |
-// |sequence_1| and |sequence_2|. |sequence_1| is taken as reference, with |
-// |sequence_1_length| as its length. |sequence_2| slides for the calculation of |
-// cross-correlation. The result will be saved in |cross_correlation|. |
-// |cross_correlation_length| correlation points are calculated. |
-// The corresponding lag starts from 0, and increases with a step of |
-// |cross_correlation_step|. The result is without normalization. To avoid |
-// overflow, the result will be right shifted. The amount of shifts will be |
-// returned. |
-// |
-// Input: |
-// - sequence_1 : First sequence (reference). |
-// - sequence_2 : Second sequence (sliding during calculation). |
-// - sequence_1_length : Length of |sequence_1|. |
-// - cross_correlation_length : Number of cross-correlations to calculate. |
-// - cross_correlation_step : Step in the lag for the cross-correlation. |
-// |
-// Output: |
-// - cross_correlation : The cross-correlation in Q(-right_shifts) |
-// |
-// Return: |
-// Number of right shifts in cross_correlation. |
