BitPar is a parser for highly ambiguous probabilistic context-free
grammars (such as treebank grammars). BitPar uses bit-vector
operations to speed up the basic parsing operations by
parallelization.
You can download the BitPar source code as a gzip-compressed tar file. It is freely available for research and education. You might also want to download the Trace Parser software package (4.5 MB) which contains an English grammar which was extracted from the PENN treebank or a similar parser for German (5.3 MB) which was trained on the Tiger treebank.
