This package is a special version of the Reed-Solomon package. It is hardwired for the (255,223) code over GF(256). The encoder is implemented entirely in optimized assembler for the Intel 386 series CPU, and the decoder has an assembler assist for computing the syndrome components. The result is a much faster encoder/decoder for this particular code than the general C version. The encoding speed on a 133 MHz Pentium is about 30 Mb/s. The decoding speed on a block without any errors is about 16 Mb/s. Phil Karn karn@ka9q.ampr.org August 1997
