SAF784x
One chip CD audio device with integrated MP3/WMA decoder
6.8 Block decoder
The general features of the SAF784x block decoder are:
32-bit microprocessor interface
Channel decoder compatible C2I interface
Segmentation manager compatible MiMeD2 interface
The main CD decode features of the SAF784x block decoder are:
16-bit data channel
Data byte swapping
Sync pattern (0x00, 0xFF to 0xFF, 0x00) detection and interpolation
Main data de-scrambling (as per the CD Yellow Book (ISO/IEC 10149)for mode 1,
mode 2 form 1 and mode 2 form 2 sectors)
Header (MSF address) monitoring, interpolation and repair
Firmware programmable 1-bit stream filtering on sector boundaries (CD-ROM only)
Fast real-time C3 error correction (including automatic detection of mode 1, mode 2
form 1, and mode 2 form-2 sectors) using an internal two sector SRAM
Separate 8-bit subcode channel
Subcode P + Q channel de-interleaving and Q channel CRC checking
Subcode CD-text mode four-packet extraction and CRC checking
Automatic subcode stream filtering associated with the data stream filter
Stream building (the main data stream, the block error byte, the error flag bytes and
the subcode channel will be merged into a single data stream for transmission to the
segment manager
Status word tag creation (which contains sector-specific information)
