Re: [oc] Reed Solomon Encoder/decoder core requirements

[ashishladdha@yahoo.com]

Hi Ppl,
        This grp is really a nice tech. grp. I wish to know whether it is 
possible to get Reed-Solomon Encoder VHDL code on Net. Or do 
anybody have it? Plz, let me know. I am in immense need of it to start 
up my project.
