Abstract: The method uses source and target registers (15,16,26 to 29) to alternately receive and take out data blocks of predefined lengths. Index symbols are selected from the contacts of the source register and used as addresses of dictionary memory (14) whose entries contain expanded data in the form of variable length character symbols. Data blocks of predefined lengths are formed from the character symbols and stored in target registers. A divider (22), a multiplexer circuit and control circuit dynamically select the target register to alternately load the target register and transmit complete data blocks to memory.
