PURPOSE:To ensure the reprocess for the upper-rank unit with no restriction in case the output information of the lower-rank unit has some error by providing the means to store the input data temporarily and the means to detect the storage allowance quantity, and thus increasing the process efficiency. CONSTITUTION:Tha data processor consists of control part 1 to control the input data information sent from the upper-rank unit in the input/output control of the data information, control part 2 to control the output data information to be given to the lower-rank unit, means 3 to store the input data information temporarily, means 4 to detect the input data amount, means 5 to detect the fact that the input data information exceeds the capacity of means 3, means 6 to send the contents of means 3 by the detected 4 amount, and others. Thus, the input data information is stored 3 temporarily, and the fact that the stored information amount is less than the capacity of means 3 is detected 5. As a result, process time a' requiring the reprocess does not need installation of the upper-rank unit. Furthermore, the installation of the upper-rank unit expressed by code d is not required even for the reprocess in case some error is detected in the result. |
