摘要： The present invention provides an integrated controller to process both optical reads and optical writes of multiple optical media. The integrated controller includes a host interface; a buffer manager coupled to the host interface; an embedded memory coupled to the buffer manager; an integrated encoding/decoding engine coupled to the buffer manager; a data channel interface coupled to the integrated encoding/decoding engine; and an integrated servo/recording processor coupled to the integrated encoding/decoding engine and the data channel interface, where the integrated servo/recording processor includes a set of write strategies. The present invention provides a controller which integrates the functionality of the conventional controllers into an integrated processor. With the controller in accordance with the present invention, a single drive may be provided which can read CD-based and DVD-based formats, read and write to Write Once Media, and read and write to Rewritable Media. The architecture of the controller is designed such that its manufacture is cost effective and a performance penalty for the host does not occur. In addition, the controller may also be used with conventional optical drives. Thus, with the present invention, the same controller may be used for all conventional optical drives as well as with an integrated drive.

摘要： The present invention provides a method and system for audio data retrieval from an optical media. The method includes reading a sector of audio data from the optical media, the sector comprising a sector data and a sector sub-code; collecting the sector sub-code; correcting any errors in the sector data in a fixed time period; calculating a time offset between a time for the collecting of the sector sub-code and the fixed time period; and matching the corrected sector data to the sector sub-code based on the calculated time offset. A method and system for retrieving audio data from an optical media has been disclosed. The present invention uses a fixed time period for the sector data error correction process. By using a fixed correction time, the sector data and the sector sub-code can be automatically matched based upon an offset calculated from the fixed correction time. In this manner, the sector data and its corresponding sector sub-code may be accurately matched without the need for complicated algorithms. This saves significant processing resources. The location from which the reading of the audio data is resumed is more accurately determined.

摘要： The present invention provides a method and system for syndrome generation for data from an optical media. The method includes reading data bytes for a plurality of columns of a row of the data; reading a plurality of partial syndromes from a memory, each of the plurality of partial syndromes corresponding to one of the plurality of columns; updating each of the plurality of partial syndromes with the data byte of the corresponding column; and writing the plurality of updated partial syndromes into the memory. The present invention obtains data bytes for multiple columns at one time. Syndrome generation is then performed for each column, with the partial syndromes for each column stored in a memory. As the data bytes of subsequent rows of data for multiple columns are obtained, the partial syndromes for each column are read from the memory and loaded into a syndrome generation logic, thus updating the partial syndrome for each column. The updated syndromes are written back into the memory. This continues until the syndromes for all of the rows for the multiple columns have been generated. By storing partial syndromes in a memory, multiple sets of syndrome generation logic is not needed to simultaneously process multiple columns of data bytes, thus avoiding a space penalty for the controller. Since multiple columns are read at one time, fewer clock cycles are required to access the data bytes, saving time. Therefore, clock cycle penalties are decreased while also avoiding a space penalty for the controller.
