MOVI2S, MOVS2I instruction equivalents

The attached file contains the implementation of two (2) custom instructions. The instructions correspond to the MOVI2S and MOVS2I classical DLX instructions. Their purpose is to provide a standard means for transfering registers from the coprocessor register file to the main (integer) register file and vice versa.

Here follows the content list:

data_transfer.vhd : The actual implementation of the custom instructions component.

data_transfer_ci.c : A simple test application.

Feel free to provide any suggestions.
