LZ4 is an LZ77-type compressor with a fixed, byte-oriented encoding. -The most important design principle behind LZ4 is simplicity. -It helps to create an easy to read and maintain source code. -It also helps later on for optimizations, compactness, and speed. There is no entropy encoder back-end nor framing layer. -The latter is assumed to be handled by other parts of the system. +The latter is assumed to be handled by other parts of the system (see [LZ4 Frame format]). +This design is assumed to favor simplicity and speed. +It helps later on for optimizations, compactness, and features. -This document only describes the block format, -not how the LZ4 compressor nor decompressor actually work. +This document describes only the block format, +not how the compressor nor decompressor actually work.
