I take that back.  After looking at the code for about 20 minutes, I 
remembered that the problem is that I DO lack the software to do this, which 
is part of the reason that the numbers are so imprecise.  In order to 
impliment the sliding ability, I did a quick rush job and used my existing 
routines.  One cosine is multiplied by the integer, then the answer is 
truncated to a whole number which is why it is so imprecise.  It then has to 
be multiplied by another cosine and is of course truncated again.  So 
essentially what I need is a routine that can multiply two 16-bit numbers and 
one 8-bit number (but in a 16-bit register) without any loss of precision.  I 
haven't really looked for one, and I'm too lazy/unskilled with routines to 
write my own
