| 20090144517 | DATA PROCESSING APPARATUS AND DATA PROCESSING SYSTEM - Decrease in throughput performance called a “jamming” in a memory device is prevented. There is provided a timing generation part which gives, based on a request signal outputted for each unit of the data processing from a data processing part, an output timing for a burst transfer request to a burst transfer request generation part. Based on the relationship in size between a lapsed time from the output of the burst transfer request to the activation of the request signal and a time specified by a set threshold value of a threshold value register, the timing generation part controls output timing for a burst transfer request. When the lapsed time exceeds the time specified by a maximum threshold value, the burst transfer request generation part is given an output timing for the burst transfer request without waiting for the activation of the request signal. As a result, when the issuance of the request signal is delayed, a next burst transfer request can be given to the memory device without waiting for the issuance but preceding it. | 2009-06-04 |

| 20090144563 | Method of detecting data tampering on a storage system - A storage system according to the invention maintains an arithmetic signature or fingerprint generated using the content of selected units of data stored on the media. The signature is stored in metadata in non-volatile storage on the system's electronics card preferably in a tamper resistant module (TRM). When reading a data unit from storage, the system uses the saved signature to verify that the data unit has not been altered by unauthorized means after it was stored. The content of the stored data is thereby bound to the metadata stored in the system's non-volatile storage so that by-passing or physically separating the bulk storage media (e.g. disks) from the system's electronics will not allow alteration of the data without detection. The method also prevents unauthorized data roll-back because the signature of old data will not match the current signature in the metadata. | 2009-06-04 |
