It offers pretty fast compression and very fast decompression .
Decompression requires no memory.
In addition there are slower compression levels achieving an excellent compression ratio while still decompressing at this very high speed. The NRV decompressors can be squeezed into less than two hundred bytes of code. NRV requires no additional memory for decompressing. NRV supports in-place decompression. NRV is based around a very sophisticated compression engine which allows easy adaption for specially tuned algorithms and other requirements.
