## README

本项目实现对数据/文件的压缩与解压缩，包含bzip、deflate、lz4、snappy、minilzo、zstd。
本项目未对其进行深入研究，未涉及如何提高使用库的压缩率或压缩速率，也未涉及多线程压缩等问题，此处只是实现基础应用来满足项目需求。

项目编译测试：
	chmod +x build.sh

	----X86系统编译
	./build.sh
	----arm交叉编译
	./build.sh -host arm-linux-gnueabihf  

	export LD_LIBRARY_PATH=$(pwd)/build/lib/
	cd example
	./wow_compress

执行结果如下：
	We successfully compressed input.txt->compressed.lz4! Ratio: 0.41
	LZ4 Compression completed in 0.0010 seconds
	LZ4 Decompression completed in 0.0005 seconds
	We successfully compressed input.txt->compressed.z! Ratio: 0.26
	ZLIB Compression completed in 0.0027 seconds
	ZLIB Decompression completed in 0.0009 seconds
	We successfully compressed input.txt->compressed.gz! Ratio: 0.26
	GZIP Compression completed in 0.0027 seconds
	GZIP Decompression completed in 0.7958 seconds
	We successfully compressed input.txt->compressed.bz2! Ratio: 0.22
	BZ2 Compression completed in 0.0115 seconds
	BZ2 Decompression completed in 0.0019 seconds
	We successfully compressed input.txt->compressed.snp! Ratio: 0.42
	SNAPPY Compression completed in 0.0003 seconds
	SNAPPY Decompression completed in 0.0002 seconds
	We successfully compressed input.txt->compressed.zsd! Ratio: 0.29
	ZSTD Compression completed in 0.0004 seconds
	ZSTD Decompression completed in 0.0003 seconds


总结：
	目前嵌入式实时操作系统小型工程使用minilzo，移植简单，只是简单的数据操作使用方便。
	目前嵌入式linux操作系统使用ZSTD，数据处理速度快，文件处理效率高效。

面向未来：
	目前很多嵌入式应用模块、HAL层架构、中间层架构、应用层逻辑实现、测试或使用工具已在开发过程中，后续逐步开源。
