Abstract
A system and method for providing data compression with high integrity is disclosed. In one aspect, the system and method includes a first interface, a second interface, and a storage. In this aspect, the method and system include providing a first compressor/decompressor coupled to the first interface and the storage providing and a second compressor/decompressor coupled to the second interface and the storage. The first compressor/decompressor compresses data from the first interface, decompresses compressed data from the storage, and provides a first data stream. The second compressor/decompressor compresses data, decompresses compressed data, and provides a second data stream. Each compressor/decompressor can monitor the input and output of the other compressor/decompressor using a common shared interface to the storage. The first compressor/decompressor monitors the second data stream and compares the second data stream to the first data stream if the second compressor/decompressor is a master device, and vice versa. In another aspect, the system has a storage means and an interface. The method and system include providing a single compressor/decompressor and error comparing means coupled with the compressor/decompressor. The compressor/decompressor alternatively compresses a portion of data and decompresses a portion of compressed data. The error comparing means compare the portion of data to the portion of the compressed data.
