PURPOSE:To shorten microprogram loading time, by loading a microprogram in a storage part in initial program loading operation together with program data, etc., while dividing the microprogram, and further loading them from the storage part to a control storage. CONSTITUTION:When a microprogram loading start instruction is set in a microprogram loading indicating means 8, the 1st microprogram consisting of an initial setting control part, initial program loading control part, and control part for control over the 2nd microprogram loading is loaded from an auxiliary storage 6 to the control storage 1. Once the loading of the 1st microprogram ends, an arithmetic control part 2 reads the 1st microprogram from a specific address of the control storage 1 to start execution. Then, a loading identification information holdig circuit 7 is read to store the read data in a specific address of a storage part 3. An input and output file control part 4 transfers data from input and output files 51 and 52 to the storage part 3. |
