Abstract

PURPOSE:To ensure a high-speed process and then realize an effective use of the external memory device within the system, by securing an independence of the function to give a high-speed compression and restoration to the information composed of the code raw from the process part of the CPU and also realizing the function with the hardware such as the LSI or the like. CONSTITUTION:Receiving the indication for start of the process, the character compressing device 102 reads the unprocessed data within the memory 104 via the memory control part 103 and based on the information given from the process part 101. Then the process indicated in the working mode is applied, and the processed data is written into the prescribed position of the memory 104. This action is given to all data, and an interruption is applied to the part 101 when the process completes. And in case the device 102 gives a process of compression, the part 101 transmits the processed data to the external unit via the communication control part 105. While in case the data received from the external unit is restored, the process restoration is completed by the interruption. In this way, a high-speed process is possible for the character compressing device, thus ensuring an effective use of the external unit in the system.
