PURPOSE:To shorten time for inspection and make a table for collation unnecessary by deciding suitability of data form based on the address comparison of processing instruction. CONSTITUTION:A data processing section 1 of an user program that performs suitability inspection and shifting of data form identifies the form of input data and selects corresponding data shifting instruction. The processing section 1 stores an address on a main memory of the shifting instruction in the first memory area 4, and at the same time, executes shifting, and if fault is generated from a fault generating section 2 due to inadequacy of data form, a fault processing section 3 obtains main memory address of user program instruction executed just before generation of fault by reading out the value of a program counter. This address is stored in the second memory area 5, and a flag is set to the area 5 by the processing section 1 with the coincidence of the address collation of areas 4, 5, and the result of judgement of inadequacy is reported. By constitution that does not judge small number of inadequacy at each trans form of the data, time for inspection is shortened and a table for collation becomes unnecessary. |
