Abstract: An effective organization and transferring of data among the functional blocks of an integrated system of a read channel of data recorded on DVD-Rom, DVD-Ram, DVD-R or CD Rom for performing Reed-Solomon decoding including off-line heroic correction, or deinterleaving, Reed-Solomon decoding is provided. The integrated system includes an input buffer, an interface with a microcontroller bus, a Reed-Solomon decoder, an embedded RAM accessed through a 17-bit bus, a descrambling and EDC control block for DVD modes of operation, a descrambling block for CD codes of operations, a data output interface, and a timing control block. The system permits the de coding of the input data acquired through the input buffer at a rate of up to four-times the reference bit rate of DVD formatted data using a clock for accessing the embedded RAM having a frequency half that of the clock that is used in the Reed-Solomon decoder, while reducing the number of accesses to the embedded RAM needed to perform the decoding.
