TurboRLE: Turbo Run Length Encoding
Efficient and fastest Run Length Encoding library
-
ARM NEON support
-
100% C (C++ compatible headers), without inline assembly
-
Most efficient compression
-
No other RLE compress or decompress faster with better compression
-
:sparkles: faster compression and 2x faster decompression with :+1: SIMD
-
:+1: Java Critical Natives Interface. Access TurboRLE incl. SIMD! from Java
-
Compress better and up to 12 times faster and decompress up to 6 times faster than other fast RLEs
-
Can be faster than memcpy!
-
:+1: ZERO! byte overhead
-
No modification of the raw data, preserving compressibility for further postprocessing (ex. entropy coding)
-
Order preserving
