+ * Function: omxVCCOMM_SAD_16x (6.1.4.1.4)
+ *
+ * Description:
+ * This function calculates the SAD for 16x16 and 16x8 blocks.
+ *
+ * Input Arguments:
+ *
+ * pSrcOrg - Pointer to the original block; must be aligned on a 16-byte
+ * boundary.
+ * iStepOrg - Step of the original block buffer
+ * pSrcRef - Pointer to the reference block
+ * iStepRef - Step of the reference block buffer
+ * iHeight - Height of the block
+ *
+ * Output Arguments:
+ *
+ * pDstSAD - Pointer of result SAD
+ *
+ * Return Value:
+ *
+ * OMX_Sts_NoErr - no error
+ * OMX_Sts_BadArgErr - bad arguments. Returned if one or more of the
+ * following conditions is true:
+ * - at least one of the following pointers is NULL:
+ * pSrcOrg, pDstSAD, or pSrcRef
+ * - pSrcOrg is not 16-byte aligned.
+ * - iStepOrg <= 0 or iStepOrg is not a multiple of 16
+ * - iStepRef <= 0 or iStepRef is not a multiple of 16
+ * - iHeight is not 8 or 16
+ *
