发明名称 Device for compressing/decompressing bit strings
摘要 This invention relates to an electronic device, for a fax machine in particular, comprising controlling means (11) capable of associating compression codes or code words with strings of source information in accordance with a first processing speed, and storing means, for example shift registers (31, 32) capable of appending the code words to one another so as to form blocks of compressed information, in accordance with a second processing speed, greater than the first. The device is also capable of "extracting" the single code words from blocks of compressed information at this second processing speed. By way of the technique of using different processing speeds, the device makes it possible to obtain total speeds of compression and/or decompression of the information respectively to be transmitted and/or received much greater than those obtainable up to now with the known devices.
