SIMD help for exemple

hi,

i decided to have a look at SIMD intrinsics instructions but there is a lt of documentation but i cannot find exemple.

So i decide once again to ask question about how to use SIMD with exemple.

i need only 2 exemple. Than i think a should be able to mixte practique et knowledge.

the first axemple is how to do when (*in1) are INT array . the traitment is inside this append in loop (*in1)[x] - (*in1)[y], the intrincis should be VSUB if i read correctky and VABS. But i need the syntaxe code.

           ONE:

            int diff1 = std::abs((*in1)[x].raw_col_min - (*in1)[y].raw_col_min);
            int diff2 = std::abs((*in1)[x].min                  - (*in1)[y].min);
            int diff3 = std::abs((*in1)[x].raw_col_max - (*in1)[y].raw_col_max);
            int diff4 = std::abs((*in1)[x].max                  - (*in1)[y].max);
            int diff5 = std::abs((*in1)[x].raw_col_min - (*in1)[y].raw_col_max);
            int diff6 = std::abs((*in1)[x].min                  - (*in1)[y].max);
            int diff7 = std::abs((*in1)[x].raw_col_max - (*in1)[y].raw_col_min);
            int diff8 = std::abs((*in1)[x].max                  - (*in1)[y].min);

and

           TWO :

            int diff1 = std::abs((*in1)[x].raw_col_min - (*in1)[y].raw_col_min);
            int diff2 = std::abs((*in1)[x].min                  - (*in1)[y].min);
            int diff3 = std::abs((*in1)[x].raw_col_max - (*in1)[y].raw_col_max);
            int diff4 = std::abs((*in1)[x].max                  - (*in1)[y].max);

and

           FOUR:

            int diff1 = std::abs((*in1)[x].raw_col_min - (*in1)[y].raw_col_min);
            int diff2 = std::abs((*in1)[x].min                  - (*in1)[y].min);

and how to do

           if ( (diff1 < 9 && diff2 < 9 && diff3 < 9 && diff4 < 9) || (diff5 < 5 && diff6 < 5 && diff7 < 5 && diff8 < 5) ){

and

          if ( (diff1 < 9 && diff2 < 9 && diff3 < 9 && diff4 < 9) ){

and

         if ( (diff1 < 9 || diff2 < 9)  &&  (diff3 < 9 || diff4 < 9) ){

i think that would be enough. Than i should be able to find my way. Or i will come back to you. ;))

Thanks a lot in advence.

PS: i work with médiatek 9200+ and Mali-G715-Immortalis MC11 r1p2
