| * Function: armVCM4P10_SADQuar |
| * |
| * Description: |
| * This function calculates the SAD between one block (pSrc) and the |
| * average of the other two (pSrcRef0 and pSrcRef1) |
| * |
| * Remarks: |
| * |
| * [in] pSrc Pointer to the original block |
| * [in] pSrcRef0 Pointer to reference block 0 |
| * [in] pSrcRef1 Pointer to reference block 1 |
| * [in] iSrcStep Step of the original block buffer |
| * [in] iRefStep0 Step of reference block 0 |
| * [in] iRefStep1 Step of reference block 1 |
| * [in] iHeight Height of the block |
| * [in] iWidth Width of the block |
| * [out] pDstSAD Pointer of result SAD |
| * |
| * Return Value: |
| * Standard OMXResult value. |
