Embodiment Construction

[0026] In FIG. 1, three parts necessary to explain the function of an intelligent buffer IBUF in front of an unshown RAMless Reed-Solomon decoder are shown.

[0027] - The first part is the acquisition block ACQ, which provides a clock byte_clk for incoming data, data_in and synchronization information on the data line.

[0028] - The second part is the address control block ADC, which generates address and control signals from the synchronization signal provided by the acquisition block ACQ; there is the address of the data stream data_in input on the data line and for the slave buffer BUF to Reed-Solomon The decoder sends the address of the output data data_out and the control output signal ctrl_out.

[0029] - The third part is the buffer BUF, which is constructed as a memory array with two ports to handle independent time schemes for output data data_out and input data_in on the data lines. It can also be constructed with an input and output port - if the input and output...

Abstract

The present invention relates to a method and apparatus for preparing data for a Reed-Solomon decoder, and more particularly to an intelligent buffer for a RAMless DVD Reed-Solomon decoder ( IBUF), and more particularly to methods and apparatus for an Intelligent Buffer (IBUF) that also acts as a first-pass error correction store for ECC blocks. In this way, out-of-order ECC blocks will not be obtained by the intelligent buffer (IBUF) Reed-Solomon decoder, which results in less RAM required and high performance of the overall circuit. An Intelligent Buffer (IBUF) is also used as a first-pass error correction store for Reed-Solomon decoders.

Description

technical field [0001] The present invention relates to a method and device for data preparation of a Reed-Solomon decoder, and more particularly, to a method for intelligence before a Reed-Solomon decoder Method and apparatus for a buffer that requires less RAM and ensures high performance. Background technique [0002] Conventional preprocessing buffers and Reed-Solomon decoders use common RAM to handle corrupted data. For example, such devices and processes are used to error correct data stored on optical information media such as DVDs for reproduction purposes. It is desirable to avoid feeding corrupted data to a Reed-Solomon decoder or use RAM to store ECC blocks or read defective parts several times - these slow down the data path rate. DVD is an acronym for Digital Versatile Disc, and ECC is an acronym for Error Correcting Code, an electronic method of checking data integrity. [0003] ECC's data is organized hierarchically into multiple dat...
