Abstract: There is described an image compressing/decompressing method and device that provides the lossless data compression/decompression scheme in two separate modules. Partially entropy encoded/decoded data is written to memory by a first module after a first part of the process and retrieved by a second module to perform the second part of the lossless compression/decompression scheme.

Abstract translation: 描述了在两个单独的模块中提供无损数据压缩/解压缩方案的图像压缩/解压缩方法和装置。 部分熵编码/解码数据在第一部分处理之后由第一模块写入存储器，并由第二模块检索以执行无损压缩/解压缩方案的第二部分。
