hi, guys:
let me set an example:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
int table[256]={......};
int lookup_tbl(int index)
{
return table[index];
}
int main()
int idx0, idx1, idx2, idx3;
int tbl0, tbl1, tbl2, tbl3;
idx0 = 2;
idx1 = 36;
idx2 = 111;
idx3 = 204;
tbl0 = lookup_tbl(idx0);
tbl1 = lookup_tbl(idx1);
tbl2 = lookup_tbl(idx2);
tbl3 = lookup_tbl(idx3);
my question is:
Could I use some neon intrinsic(maybe VTBL) to get the 4 values once? if I have set the index into a 32x4_t variable ?
thank you very much.
