Bit Slicing - Modern Use

Modern Use

In more recent times, the term bitslicing was re-coined by Matthew Kwan to refer to the technique of using a general purpose CPU to implement multiple parallel simple virtual machines using general logic instructions to perform Single Instruction Multiple Data operations. This technique is also known as SWAR, SIMD Within A Register.

This was initially in reference to Eli Biham's 1997 paper A Fast New DES Implementation in Software, which achieved significant gains in performance of DES by using this method.
