Can I run applications run completely from of CPU cache

Hi,

is there a way I could get all my code (if I know its small enough)
into the cache, and then run all instructions from the CPU cache? The
data bits could still come from the main memory.

I am looking for a main memory test program, which has to test almost
the whole memory, except, ofcourse, the resident part of the OS etc...
This program should also be as fast as possible.

hence the idea.

Any takers?? Any thoughts, suggestions ??
