Go up one level in this thread


I don't know if they can test it. The only code which is high enough level would
be permutation coder or radix coders. The general entropy coding stuff is very
low level, just the basic inner loop coder gear (where the essential differences
from the arithmetic coding are), which one needs to combine into a full coder
which serializes entire output into a single package. If they want to run
benchmarks, I would probably need to extract and clean up for public consumption
the code I used for benchmarking in the main research prototype program. Or if
they set up arithmetic coder under the same conditions and time just its inner
coder loops and use the size of its raw index (removing thus the model info,
data sizes or adaptation), they could compare apples with apples. Readme.txt has
some tips on this kind of test. I guess, I'll wait and see what they need or ask
for the testing.
