Abstract: A system and method for pseudo-randomly allocating page table memory for test pattern instructions to produce complex test scenarios during processor execution is presented. The invention described herein distributes page table memory across processors and across multiple test patterns, such as when a processor executes “n” test patterns. In addition, the page table memory is allocated using a “true” sharing mode or a “false” sharing mode. The false sharing mode provides flexibility of performing error detection checks on the test pattern results. In addition, since a processor comprises sub units such as a cache, a TLB (translation look aside buffer), an SLB (segment look aside buffer), an MMU (memory management unit), and data/instruction pre-fetch engines, the test patterns effectively use the page table memory to test each of the sub units.

If any cell indicates a fatigue condition, the data from the block of cells indicating the fatigue is moved to another block. In one embodiment, an error detection and correction process is performed on the data prior to being written into another memory block.

The access checking part determines whether an address to be accessed through a first communication path by a monitored side core and an access mode are coincident with the stored address and the stored access prohibiting mode. When the coincidence is determined, the access of the monitored side core to the count RAM area of the monitoring side core is prohibited.

Abstract: In one embodiment, a control system supports an unlimited number of feedback control loops all sharing control of a component. A component performance rate or “speed” is used as a common metric for negotiating control of the component. Each control loop continuously monitors a system parameter it is tasked with regulating, compares it to a setpoint for that system parameter, and “requests” a speed in relation to the deviation of the associated system parameter from the corresponding setpoint. A controller receives the requested speeds as dynamic inputs and selects one of the requested speeds according to predefined selection logic. The controller communicates the selected speed to an actuator, which causes the component to operate at the selected speed. In this manner, the control system in effect negotiates control of the component in a way that ensures that all of the system parameters are being managed within safe limits.

Abstract: A data replacement processing method is disclosed. In the present invention, buffering and decoding are not interrupted when a data block to be replaced is found. The data block to be replaced can be a defect or a remapped block. The data block to be replaced is not processed until it is requested to be transferred. When the data block to be replaced is to be transferred, transferring is stopped and the data block to be replaced is processed. Therefore, efficiency of the optical disc drive can be promoted since interruption number of the buffering and decoding is decreased. In addition, the optical disc will not execute redundant processing for data blocks to be replaced which are not requested to be transferred.
