Reed Solomon II decoder does not detect error packets

Hi SK,

My customer looked at the RS1 manual and RS2 manual and observed

On page 3-4 of the RS1 manual:

Errors <= R/2 : Detects & Corrects

R/2 <= Errors <= R : Detects only

Errors > R : Unpredictable

On page 3-3 of the RS2 manual:

e <= R/2 : Detects & Corrects

R/2 < e : “Decoder asserts error signal and decoding fails. The probability that the decoder might not assert the error signal is less than 1/t”

In layman’s terms, the RS 2 decoder is not as good as the RS 1 decoder! It seems like the designer of RS 2 knew about this limitation from the beginning.

My customer needs the performance of RS1 in Cyclone 10 LP, but currently support is limited to Cyclone IV. Considering the architecture of Cyclone IV and Cyclone 10 LP is the same, what is the likelihood of having RS1 ported to the Cyclone 10 LP?

thanks

Carl
