摘要： A system for transferring data read from a data storage medium. The system comprises a memory unit, a controller, a memory management logic, and an output interface. The memory unit stores the data. The controller compares at least one address of the data with at least one defect address and generates a defect notification signal indicating the comparison result. The memory management logic calculates the amount of the data stored in the memory unit for transfer and generates a calculation signal according to the amount of the data and the defect notification signal received from the controller. The output interface retrieves the data from the memory unit and transfers the retrieved data according to the calculation signal received from the memory management logic.

摘要： A data processing system is disclosed. The system includes a processor, a transformer, a first memory buffer, a second memory buffer, a first filter, and a second filter. An obtained transmission signal symbol is first transformed to first data. The first memory buffer stores the first data. The processor obtains peak data based on the first data according to a predetermined threshold. The transformer transforms the peak data to second data and stores the second data in the second memory buffer. The first filter filters the second data to determine reserved data of the second data and removes the reserved data from the second data to generate third data. The transformer transforms the third data to fourth data and stores the fourth data in the second memory buffer. The processor merges the first and fourth data to generate fifth data. The second filter filters the fifth data based on the transmission signal symbol and a previously obtained transmission signal symbol.

摘要： An optical storage medium recording apparatus is provided a data preparing and ECC encoding circuit that both prepares the data by combining different categories of data into data sequences in accordance with a data layout on the optical storage medium and encodes the combined data. The encoded data is temporarily stored in a data buffer, and subsequently successively read out by a recording circuit for recording onto the optical storage medium according to the data layout. For a Blu-ray disc recording apparatus, the data preparing and ECC encoding circuit includes a LDC/BIS encoder for generating long distance error correction codes (LDC) and burst indicator subcodes (BIS) from the combined data to form LDC and BIS encoded data, which is temporarily stored in the data buffer. The recording circuit includes an interleave circuit for interleaving the LDC and BIS data to form physical clusters for recording on the disc.
