I believe that your solution is a SIMD instruction that performs
"byte shuffling". I've seen it appear in big CPUs years ago.
Why isn't it used for this purpose ?

No,

 why ?

tiling is used for better use of cache. SIMD did not provide such
feature.

It can, if you think it through...

a solution is to change the way memory adress are translated
inside the 4ko.
how ?
By using a conversion function to translate naturel adress to the real
memory address.

what is this conversion function ?
