DATA FORMAT CHECKING PROCESSOR

摘要

PURPOSE:To prevent the overlapping development of similar data format checking processings and to reduce the development scale of the data checking part of an information processing system by providing generally applicable features with improved extendability by placing information required for checking at the outside of a device and turning a checking execution part corresponding to checking items to a module and performing application to the data checking part of the information processing system. CONSTITUTION:This processor is constituted of five blocks and the two kinds at checking processing control data, item decomposition data and item checking data. Inputted input data are decomposed into the minimum units of a checking object called items based on the item decomposition data and further, the checking of more than one single item is separately executed based on the item checking data for the decomposed input data. By performing the processing of a logical operation or the like based on the item checking data to the results of the single item checking, the validity of the input data is judged in general.
