PURPOSE:To obtain the data processor which can improve the processing efficiency of data. CONSTITUTION:An asynchronous processing means 100 executes a main memory access processing asynchronously to the instruction execution processing of an instruction processor 1 and when the processing is interrupted by generating various access exceptions at a dynamic address translating device or an address translating buffer 8, information required for restarting the interrupted processing is detected by a detecting means 50. Then, the detected information required for restarting the interrupted processing is held in holding means 15 and 17 and when the access exception is generated, the held information required for restarting the interrupted processing is informed of a program to process the access exception. |
