/**
* Function: omxVCCOMM_SAD_8x (6.1.4.1.5)
*
* Description:
* This function calculates the SAD for 8x16, 8x8, 8x4 blocks.
*
* Input Arguments:
*
* pSrcOrg - Pointer to the original block; must be aligned on a 8-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 8-byte aligned.
* - iStepOrg <= 0 or iStepOrg is not a multiple of 8
* - iStepRef <= 0 or iStepRef is not a multiple of 8
* - iHeight is not 4, 8 or 16
*
