whereas in the case of CD-ROM data it is embedded in the main channel data. Once the
Target Header is found the data transfer to the Buffer starts and the de-scrambling is done
while storing the data in the buffer from the disc. This data is than transferred to the Host
(ATAPI or Audio DAC interface)
In the case of CD-ROM data, depending on the format additional C3 correction needs to
be performed. This flow is similar to the DVD case, i.e. when sufficient sectors are
available in the buffer, the ECC engine starts correcting the data and the Host transfer
starts as soon as sufficient sectors are available after C3 correction.
Data Channel
The CL-CR3710 contains a partial response maximum likelihood (PRML) read channel.
The channel takes the analog signals from the optical pickup's (OPU) photo detector
outputs, detects the EFM or EFM+ data, and sends the data to the decoder.
