    摘要: When a control unit is in a non-operating (non-printing) state, data to be saved (character-image data) in a RAM cache memory is transferred to a disk cache memory at regular intervals in order of priority, thereby saving the data in the disk cache memory. If a power supply is cut off and then power is reintroduced, high-priority character-image data, which has been transferred from the RAM cache memory to the disk cache memory and saved in the disk cache memory when printing is not being carried out, is restored in the RAM cache memory. As a result, the high-priority data saved in the RAM cache memory when the power supply was cut off can be restored in the RAM cache memory, thereby raising the hit rate.

    摘要: A method for transferring data from one memory to another within a memory hierarchy in a data processing system. The memory hierarchy includes a random access memory (RAM) cache within a control unit and a lower level disk cache memory. When the control unit is in a non-operating (non-printing) state, data to be saved (character-image data) in the RAM cache memory is transferred to the disk cache memory at regular intervals in order of priority, thereby saving the data in the disk cache memory. If a power supply is cut off and then power is reintroduced, high-priority character-image data, which has been transferred from the RAM cache memory to the disk cache memory and saved in the disk cache memory when printing is not being carried out, is restored in the RAM cache memory. As a result, the high-priority data saved in the RAM cache memory when the power supply was cut off can be restored in the RAM cache memory, thereby raising the hit rate.

    摘要: An image control apparatus includes a communication control unit for effecting a communication with the outside of the apparatus, an image processing control unit for controlling processings required for a given image data, and a main control unit for controlling the communication control unit and the image processing control unit. Respective control units are provided on separate printed boards, respectively, and each printed board is connected to each other using respective connectors. By the constitution, it is possible to make a maximum use of resources such as hardware resources and thereby improve an efficiency in development of the image control apparatus. Also, by mounting the above printed boards with being divided into lower-side units and upper-side units, it is possible to increase the component mounting space and to have the printed board drawings for common use.
