Hm, there are various ways ... whithout hardware, with hardware, the 
oldschool-way and so on...
the oldschool-way is with a variation of the Bresenham's 
algorithm.  Newschool is, you decide how many segments your circle will 
have, make a table of sines and a table of cosines of #segments length, and 
then your read costab, multiply with radius -> that's x_coordinate, read 
sintab, multiply with radius -> y_coord.  now you draw staight lines 
between two of those pairs of coordinates, then loop thru your segments in 
this manner. easy, isn't it?  Just simple math.
