decode_rs8

Name

decode_rs8 --  Decode codeword (8bit data width)

Synopsis

int decode_rs8 (struct rs_control * rs, uint8_t * data, uint16_t * par, int len, uint16_t * s, int no_eras, int * eras_pos, uint16_t invmsk, uint16_t * corr);

Arguments

rs

the rs control structure

data

data field of a given type

par

received parity data field

len

data length

s

syndrome data field (if NULL, syndrome is calculated)

no_eras

number of erasures

eras_pos

position of erasures, can be NULL

invmsk

invert data mask (will be xored on data, not on parity!)

corr

buffer to store correction bitmask on eras_pos

Description

The syndrome and parity uses a uint16_t data type to enable symbol size > 8. The calling code must take care of decoding of the syndrome result and the received parity before calling this code.
