Hi All,
I am currently using this code to retrieve data from a data capture
board

unsigned char data[1024], *data_ptr;
data_ptr = data;

for(x = 0; x < 1024; x++)
    *data_ptr++ = inportb(0x246);

I am giving the compiler the -O3 option

Only trouible is, my for() loop is not fast enough. 
I am thinking there is not much there to optimize and that even if I
wrote the function in assembler it wouldn't be much quicker. 
But I figured I'd ask you guys first before I declare the program
unfeasable.
Any ideas ?
