Abstract
PURPOSE: To prevent a delay of the data processing by the regenerative work of a data, by regenerating a compressed data to its original data by means of hardware, in the data processing system for compressing an input data.
CONSTITUTION: When the head address of a compressed data is set into the memory address register 12 by the program, a flag data corresponding to the head address is input into the memory register 13. Its flag data is sent to the shift register 15 by decision of the channel control part 17, and it is shifted one bit by one bit. In case when the bit which has been shifted is "0", the data stored in the buffer register 19 at the last time is selected, and it is output as a regenerative data to the channel interface 20. Also, in case when the bit which has been shifted is "1", a data which has been read out to the memory data register 13 from the memory is output as a regenerative data.
