RealTime Data Compression: 11/23/14 - 11/30/14

http://fastcompression.blogspot.com/2014_11_23_archive.html

Development blog on compression algorithms. Tuesday, November 25, 2014. Portability woes : Endianess and Alignment (Part 2). Endianess and 32/64 bits detection were detailed. Now we'll have a look at more complex memory alignment troubles. Is a lesser known issue, but its impact can be huge : it will crash your program or result in a disproportionate slow down. But it has a cost, it makes the CPU more complex, and consume some precious transistor space. As a consequence, several CPU vendors selected ...

RealTime Data Compression: Zstandard

http://fastcompression.blogspot.com/p/zstandard.html

Development blog on compression algorithms. Short for Zstandard, is a new lossless compression algorithm, which provides both good compression ratio. Standard" translates into everyday situations which neither look for highest possible ratio (which LZMA and ZPAQ cover) nor extreme speeds (which LZ4. A reference source code is provided as a BSD-license package, hosted on Github. Which also host some up to date compression benchmark. You can download latest release here. June 9, 2015 at 9:46 PM. Perhaps su...

RealTime Data Compression: 5/24/15 - 5/31/15

http://fastcompression.blogspot.com/2015_05_24_archive.html

Development blog on compression algorithms. Friday, May 29, 2015. Since I started programming a few years ago, and selected data compression as my little hobby and obsession, I nonetheless remained a part-time, amateur, programmer. I therefore started programming with a good excuse : I was convinced that it helped me understand and communicate with programming teams, hence making me a better. That couldn't last. With a baby soon to come, it became clear that I would either have to stop, by starvation...

RealTime Data Compression: LZ4

http://fastcompression.blogspot.com/p/lz4.html

Development blog on compression algorithms. LZ4 is a very fast lossless compression algorithm, providing compression speed at 400 MB/s per core, scalable with multi-cores CPU. It also features an extremely fast decoder, with speed in multiple GB/s per core. Typically reaching RAM speed limits on multi-core systems. LZ4 is available as a C. Open Source project, hosted on. Under a BSD license. A list of ports to other language (Java, C#, Python, etc.) is also maintained on this page. Version 1.4.1). M 2 Op...
