| * The following 2 functions ('cal_nmvjointsadcost' and * |
| * 'cal_nmvsadcosts') are used to calculate cost lookup tables * |
| * used by 'vp9_diamond_search_sad'. The C implementation of the * |
| * function is generic, but the AVX intrinsics optimised version * |
| * relies on the following properties of the computed tables: * |
| * For cal_nmvjointsadcost: * |
| * - mvjointsadcost[1] == mvjointsadcost[2] == mvjointsadcost[3] * |
| * For cal_nmvsadcosts: * |
| * - For all i: mvsadcost[0][i] == mvsadcost[1][i] * |
| * (Equal costs for both components) * |
| * - For all i: mvsadcost[0][i] == mvsadcost[0][-i] * |
| * (Cost function is even) * |
| * If these do not hold, then the AVX optimised version of the * |
| * 'vp9_diamond_search_sad' function cannot be used as it is, in which * |
| * case you can revert to using the C function instead. * |
