Eulerian Technologies IAB TCFv2 high speed reader implementation (in C)

(gcc linux)

API

  etcfv2_t * etcfv2_parse( char *s );
  void etcfv2_free( etcfv2_t * );
  void etcfv2_ids( etcfv2_t * );

and direct access to public structure etcfv2_t (in include/etcfv2.h)

High speed decode:

Result on a simple i5-3570 +500K TCData per second

without ids remap: bitfield access

# time ./src/test1
Proc: 1000000

real	0m1.225s
user	0m1.225s
sys	0m0.000s

with direct ids

time ./src/test1
Proc: 1000000

real	0m1.661s
user	0m1.660s
sys	0m0.000s

Extract format:

# ./test1
