    Buy a beagleboard... http://www.watterott.../BeagleBoard-xM
    This is not very expensive !!!

    Unfortunately, it is big money for me. Also, this board is hard to buy in my country:(
    Webshaker, you said you count the number of cycles when instructions come to "functional unit". By "functional unit", you mean execution stage, don't you?
    Could you explain for me the way you define 2 instructions that can be executed concurrently, in pipe0 and pipe1?
