ABSTRACT:
A system for detecting access to a storage in a data processing apparatus which includes an address translation look-aside buffer which holds a part of an address translation table listing correspondences between logical addresses and real addresses, entry of the translation look-aside buffer being referred to upon every access to the storage. Each of the entries is added with information bit indicating whether a storage region corresponding to a given entry includes an area which is allocated for the detection of the access to the storage. Detection as to whether an address for accessing the storage is located within the area allocated for the access detection is not carried out when the identification information indicates that the storage region to be accessed does not include the area allocated for the access detection.
