摘要： A data processing system includes a data input configured to receive input blocks of data, a memory configured to store the input blocks of data, a data processor configured to process the input blocks of data and to yield corresponding processed output blocks of data and a scheduler configured to cause the data processor to output the output blocks of data after a processing criterion has been met in the data processor. The memory is configured to retain the input blocks of data for reprocessing after the corresponding processed output blocks of data have been output from the data processor. The scheduler includes a control input configured to receive reprocessing requests for the retained input blocks of data. The scheduler is configured to initiate a reprocessing operation in the data processor for the retained blocks of data when the reprocessing requests are received on the control input.

摘要： Hardware-based methods and apparatus are provided for inter-track interference mitigation in magnetic recording systems. Inter-track interference (ITI) is mitigated in a magnetic recording system by obtaining ITI cancellation data; and providing the ITI cancellation data to an ITI mitigation circuit using a write data path in the magnetic recording system. The write data path can optionally operate substantially simultaneously with the read data path performing the read operation. The ITI cancellation data comprises, for example, user data and/or media data.
