发明名称 Parallel data compression and decompression
摘要 <p>An apparatus and method for parallel data compression and decompression uses packing and unpacking of data which has multi-variable components, for example, relational multi-variable content data such as tristimulus color space data used in color hard copy applications. Multiple input words are compressed in parallel compression engines and fed in parallel to a packer device which configures the codes in an order determined by order of compression and byte count for each word into a single bit string code. In the decompression cycle of the process, an unpacker device separates the single bit string code based upon length of a data string represented by a code word last decoded by either the decompression engine for that code word if the decompression engine is idle, or the length of the string that has been decoded so far if the decompression engine is currently working on a code.</p>
