+ * Function:  omxVCCOMM_Copy8x8   (6.1.3.3.1)
+ *
+ * Description:
+ * Copies the reference 8x8 block to the current block. 
+ *
+ * Input Arguments:
+ *   
+ *   pSrc - pointer to the reference block in the source frame; must be 
+ *            aligned on an 8-byte boundary. 
+ *   step - distance between the starts of consecutive lines in the reference 
+ *            frame, in bytes; must be a multiple of 8 and must be larger than 
+ *            or equal to 8. 
+ *
+ * Output Arguments:
+ *   
+ *   pDst - pointer to the destination block; must be aligned on an 8-byte 
+ *            boundary. 
+ *
+ * Return Value:
+ *    
+ *    OMX_Sts_NoErr - no error 
+ *    OMX_Sts_BadArgErr - bad arguments; returned under any of the following 
+ *              conditions: 
+ *    -   one or more of the following pointers is NULL: pSrc, pDst 
+ *    -   one or more of the following pointers is not aligned on an 8-byte 
+ *              boundary: pSrc, pDst 
+ *    -    step <8 or step is not a multiple of 8.
