Nios II custom instruction faster in 32bit or 128bit

Hi all, Will the NIOS II run faster processing 128bit data using 128-bit custom instruction or 32bit custom instruction and run 4 times? Since NIOS II is 32-bit processor. Thanks..

i see.. thanks for your help.. now i have clearer picture.

btw.. i have another question regarding the c code programming in nios II. As if i send a char type or any other type of data to the custom instruction, how will it be inteperate? ASCII or original data itself?

thanks...
