decode_rs169
Decode codeword (16bit data width)
Usage
int decode_rs16(struct rs_control * rs, uint16_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
Overview
Each field in the data array contains up to symbol size bits of valid data. Returns the number of corrected bits or -EBADMSG for uncorrectable errors.
