ContributorHigh-Speed Reed-Solomon IP Core polynomial
Hi
I am planning to use Intel's High-Speed Reed-Solomon IP Core for my requirement with RS-FEC (198,194) with below polynomials.
"
An RS(198,194) code over GF(28) is used:
The primitive polynomial over GF(28) is p(x) = X^8 + X^4 + X^3 + X^2 + 1
The generating polynomial is g(x) = X^4 + 15X^3 + 54X^2 + 120X + 64
"
Can anyone let me know how the "Field polynomial" field be mapped to to the required polynomial?
With regards,
HPB
- Hi HPB, As I understand it, you have some inquiries related to configuring the high speed reed solomon IP to have GF(2^8) with primitive polynomial of p(x) = X^8 + X^4 + X^3 + X^2 + 1. For your information, this p(x) would be corresponding to decimal number of 285. In other words, at the Field polynomial drop down in the IP, you may select "285". Please let me know if there is any concern. Thank you. Best regards, Chee Pin
