CD-ROM (ELM)
Preliminary specification
SAA7382
1 FEATURES
CD-ROM (Mode 1) and CD-I (Mode 2 - Form 1 and
Form 2) formats supported
Real-time error detection and correction in hardware
Suitable for double speed, n = 2.
Maximum host transfer burst rate of 8.3 Mbyte/s
Corrects two errors per symbol with erasure correction
36 kbit of on-chip error correction buffer RAM
12-byte command FIFO and 12-byte status FIFO
Compatible with the Advanced Technology Attachment
(ATA) register set and the Advanced Technology
Attachment Program Interface (ATAPI) command set
Operates with popular memories. (up to 128 kbyte
SRAM; 1 to 16 Mbit DRAM, different speed grades,
nibble or byte wide)
Interface to Integrated Drive Electronics (IDE) bus
without external bus drivers
Q-to-W subcode buffering, de-interleaving and
correction are supported
Device can operate with audio RAMs. A RAM test allows
bad segments to be identified.
2 GENERAL DESCRIPTION
The SAA7382 decoder is a block decoder buffer manager
for high-speed CD-ROM applications that integrates
real-time error correction and detection and host interface
data transfer functions into a single chip.
The SAA7382 has an on-chip 36-kbit memory. This
memory is used as a buffer memory for error and erasure
corrections. The chip also has a buffer memory interface
thus enabling the connection of SRAM up to 128 kbytes, or
DRAM up to 16 Mbits. The on-chip memory is sufficient to
buffer 1 sector of data. The external memory can buffer
many more, depending on memory size.
The error corrector of the SAA7382 can perform 2-pass
error correction in real-time. Buffer memory for this
correction is integrated on-chip.
The SAA7382 has an host interface that is compatible with
the SANYO LC89510 or OAK OTI-012 and also
compatible with the ATA/IDE/ATAPI hard disc interface
bus. (All ATAPI registers are present in hardware).
Supply of this Compact Disc IC does not convey an implied
license under any patent right to use this IC in any
Compact Disc application.
