Abstract: PROBLEM TO BE SOLVED: To provide a pipeline type data processor for performing the random execution and inference execution of instructions by allocating intrinsic identifiers to the respective instructions and using the identifiers again during the execution of a program inside a data processing system. SOLUTION: This data processing system is provided with an input circuit and a memory for storing plural control values corresponding to the identifiers of plural targets and the memory is provided with first and second banks. Also, a target identification circuit for generating plural target identification values and continuously allocating the respective target identifiers to the corresponding instructions is provided as well. When the target identification values corresponding to the plural control values are allocated inside the first and second banks, the target identification circuit selectively reallocates the first part of the plural target identification values corresponding to the first part of the plural control values inside the first bank. The data processing system 100 is provided with a pipeline type CPU 110 and the CPU 110 is connected to other various constituting elements by a system bus 112.
