This IP is a part of LabVIEW FPGA RF Communications Library available on NI Labs.

This IP performs normal/ shortened Reed-Solomon encoding for code word length(n)=255, data word length(k)=239.

The IP specification is as mentioned below:

• Implements Reed-Solomon code (255, 239)

• Code word length (n)= 255 symbols

• Data word length (k)= 239 symbols

• Field generator polynomial p(x) = x^{8 + x}4 + x^{3 + x}2 + 1

• Code generator polynomial g(x) = (x + a^{0)(x + a}1)(x + a^{2)…(x + a}15); a=0x02

• Supports code shortening

• Maximum clock rate=80MHz

• Supports data rates <=clock rate

• Fully synchronous design , with speed optimization

• Device utilization summary (Xilinx Virtex II Pro P30):

• Number of BUFGMUXs            6   out of      16   37%

• Number of External IOBs     371   out of     556   66%

• Number of RAMB16s             1   out of     136    1%

• Number of SLICEs           1087   out of   13696    7%
