Version 0.9 released

Version 0.9 is a feature release.

The --slice-by option is a major new feature. It enables a variant of the table-driven algorithm that operates on 32 bits of data or more at a time rather than 8 bits. This can dramatically speed-up the calculation of the CRC, at the cost of increased code and data size. Note: this option is still experimental and not well-tested. Check your results and please raise bugs if you find problems. Also not all CRC models can be used currently with the --slice-by option. This will change in future.

Compliance with PEP 0008 required a change in the python API. Member variables of classes should be in lowercase and not in CamelCase.

Version 0.8 released

Version 0.8 is a bugfix release.

The bitwise-expression generator is an experimental feature, which might one day be almost as fast as the table-driven code but much smaller. At the moment the generated code is bigger and slower than any other algorithm, so use at your own risk.

Version 0.7.5 released

Version 0.7.5 is a feature enhancement and bug fix release:

Version 0.7.5 introduces a C/C++ API change: this version introduces the additional (internal) parameter crc_shift in the crc_cfg_t structure. This variable is used by the table-driven algorithm when the width is not defined during code generation. This variable is zero if the width is ≥ 8.
