|
|
A fork of Intel's Hyperscan, modified to run on more platforms. Currently
|
|
ARM NEON/ASIMD is 100% functional, and Power VSX are in development.
|
|
ARM SVE2 will be implemented when hardware becomes accessible to the
|
|
developers. More platforms will follow in the future, on demand/request.
|
|
|
|
Vectorscan will follow Intel's API and internal algorithms where possible,
|
|
but will not hesitate to make code changes where it is thought of giving
|
|
better performance or better portability. In addition, the code will be
|
|
gradually simplified and made more uniform and all architecture specific
|
|
code will be abstracted away.
