    摘要: Optical disk players include a disk spinning system that is configured to spin an optical disk at a constant linear velocity and a burst cutting area decoding system that is configured to decode data in a burst cutting area of the optical disk, while the optical disk is spinning at the constant linear velocity. The burst cutting area data decoding system may be configured to determine a rotational frequency of the optical disk while reading the data in the burst cutting area, and using the rotational frequency that was determined to decode the data in the burst cutting area that was read.

    摘要: An on-the-fly error checking and correcting system and method of supporting a non-volatile memory processes data using an on-the-fly error correction method to be performed between a temporary memory and a flash memory. The flash memory stores actual data read from the temporary memory and parity generated on-the-fly in a write mode, and transmits the stored data to the temporary memory, computes a syndrome from the stored data on-the-fly, and generates an error correction information signal according to the result of computing in a read mode. Thus, error correction may only be selectively performed.

    摘要: Provided are a restoration system and method for an optical disc, by which a radio frequency signal optically picked up from an optical disc is restored. The restoration system includes a slice, a phase locked loop, a latch circuit, a 3T correction circuit, and a demodulator. In particular, the 3T correction circuit includes an extension storage device, a length measuring device, a phase detector, and an extension determiner and corrects data output from the extension storage device. In the restoration method, data required for determining the need for correction and the direction of correction is detected and a plurality of steps for selecting non-correction, two directional correction, forward correction, and backward correction are performed, thereby correcting the high radio frequency signal according to conditions of the high radio frequency signal. It is preferable that the restoration system operates according to the restoration method.

    摘要: A memory controller includes an digitally programmable delay unit having a selectable delay time receiving a read-enable signal and outputting a delayed read-enable signal. The delay time is selected in response to an externally applied delay-control signal. A sampling unit in the memory controller outputs data received from a separate memory, in synchronization with the delayed enable signal. The delay time may be a multiple of the period of a clock signal.

    摘要: A frame synchronization signal detection apparatus includes a synchronization signal detector, a main frame synchronization signal generator, a sub frame synchronization signal generator, and an output unit. The synchronization signal detector detects and outputs a synchronization signal from a digital data signal. The main frame synchronization signal generator detects and outputs a first valid synchronization signal from the synchronization signal, as an internal frame synchronization signal, and generates and outputs a first insertion synchronization signal, as the internal frame synchronization signal, if the first valid synchronization signal is not detected in a predetermined first time period. The sub frame synchronization signal generator detects and outputs a second valid synchronization signal from a synchronization signal. The output unit outputs a frame synchronization signal. The main frame synchronization signal generator stops generating the first insertion synchronization signal, and detects and outputs a first valid synchronization signal as an internal frame synchronization signal.
