+ * Function:  omxVCM4P10_SAD_4x   (6.3.5.4.1)
+ *
+ * Description:
+ * This function calculates the SAD for 4x8 and 4x4 blocks. 
+ *
+ * Input Arguments:
+ *   
+ *   pSrcOrg -Pointer to the original block; must be aligned on a 4-byte 
+ *            boundary. 
+ *   iStepOrg -Step of the original block buffer; must be a multiple of 4. 
+ *   pSrcRef -Pointer to the reference block 
+ *   iStepRef -Step of the reference block buffer 
+ *   iHeight -Height of the block; must be equal to either 4 or 8. 
+ *
+ * Output Arguments:
+ *   
+ *   pDstSAD -Pointer of result SAD 
+ *
+ * Return Value:
+ *    OMX_Sts_NoErr, if the function runs without error.
+ *    OMX_Sts_BadArgErr - bad arguments: if one of the following cases occurs: 
+ *    -    One of more of the following pointers is NULL: 
+ *         pSrcOrg, pSrcRef, or pDstSAD 
+ *    -    iHeight is not equal to either 4 or 8. 
+ *    -    iStepOrg is not a multiple of 4 
+ *    -    Any alignment restrictions are violated
