Hi Arthur,

Thanks for this.  The example in RFC 3385 is based on Verilog, which is 
less than ideal for the Vorbis I-D.  There is a C example in RFC 3309 
which I will have a closer look at.  What I will do, if it is best to 
document in the I-D itself, is to cover the polynomial as well as a C 
implementation and draw from the two RFC's as a guide.

Regards

Phil
