PROCESSING SUBSTATION SYSTEM, AND DATA PROCESSOR UTILIZED THEREFOR

摘要

PROBLEM TO BE SOLVED: To reduce the load of data processing by transmitting processing data from a 1st data processor having an output means to a 2nd data processor and receiving output data outputted by the 2nd data processor. ;SOLUTION: A CPU 10 of a small scale processor 2 requests connection of communication line with a large scale processor 6 and after the connection with communication line, the CPU 10 transfers prepared image data to the large scale processor 6. Continuously, an input/output part 36 at the large scale processor 6 receives these data and a CPU 30 performs color converting processing to these received data as a communication data converting means. Then, the CPU 30 returns the converted data to the small scale processor 2 as output data and based on these output data, images are visualized. Thus, only the color converting processing requiring high-speed processing is requested to the high-speed CPU while utilizing the inexpensive CPU.;COPYRIGHT: (C)1998,JPO
