Function Documentation

BFU QDF_dgn_gen_cal_trg_decode ( QDF_dgnCalTrg *  trg,
unsigned int  calHiLo,
unsigned int const *  src,
unsigned int  max,
BFU  bfu 
)

Decodes the CAL trigger bits portion of the diagnostic data.

Returns:
The updated BFU (current word being decoded and the current bit position).
Parameters:
trg The diagnostic CAL trigger structure to hold the decoded data.
calHiLo The map of towers that have encoded trigger bits
src The input bit stream to be decoded
max The maximum number of bits in the bit stream
bfu The value of the current 32-bit word being decoded and the current bit position.

BFU QDF_dgn_gen_hdr_decode ( QDF_maps *  dmaps,
unsigned int const *  src,
unsigned int  max,
BFU  bfu 
)

Decodes two difference maps

Returns:
The updated BFU (current word being decoded and the current bit position).
Parameters:
dmaps Returned with the values of the two maps
src The input bit stream to be decoded
max The maximum number of bits in the bit stream
bfu The value of the current 32-bit word being decoded and the current bit position.

BFU QDF_dgn_gen_tkr_accept_decode ( QDF_dgnTkrAccept *  accept,
unsigned int  map,
unsigned int  err_map,
QDF_tkrEvt const *  tkr,
unsigned int const *  src,
unsigned int  max,
BFU  bfu 
)

Decodes the TKR accept bits portion of the diagnostic data.

Returns:
The updated BFU (current word being decoded and the current bit position).
Parameters:
accept Array of the 72 accept bits for each tower
map The map of towers that have encoded accept bits.
err_map The map of towers that have tracker readout errors.
tkr The TKR data. The encoded data are the exceptions and must be XOR'ed with the TKR accept bits found in the data to produce the TKR diagnostic accept bits.
src The input bit stream to be decoded
max The maximum number of bits in the bit stream
bfu The value of the current 32-bit word being decoded and the current bit position.
