Chapter 1 About SCSIDE

1.1 Revolutionary Technology

®
SCSIDE is a revolutionary new technology developed by ACARD Technology
Corp. It can not only transform IDE data into SCSI type, but also save the
expenditures. Through this technology any cheap IDE device can have high-
performance SCSI applications. The following examples are merely a little portion
®
of SCSIDE applications.
1. To transform an IDE hard disk into an external SCSI one for notebook and desktop
PC users to back up data.
2. To transform an IDE CD-ROM or CD-R/RW into a SCSI one. It is an unprecedented
technology.
−
3. To transform your favorite IDE DVD-ROM, DVD-RAM/R, DVD R/RW or
DVD+R/RW into an LVD SCSI one.
®
4. To daisy chain multiple SCSIDE DVD-ROMs to create a DVD-ROM server.
5. To transform a DMA 66/100/133 hard disk of 5400rpm or 7200rpm into a SCSI
one for PC workstations, servers and even Unix workstations and servers.

The basic structure of SCSIDE is a "System On Chip" which highly integrates
multiple CPUs. This SOC design is resulting from ACARD's years of experiences
in the design of IDE, SCSI and RISC CPU chips. The block diagram on the next
page shows that SOC has multiple CPUs. Its ROM, RAM, DMA controllers and
external ROM interface can be used as the firmware upgrade of flash ROM. In
ACARD's technologies there is a perfect firmware design as well. It makes the
transformation of IDE to SCSI really "plug and play". The firmware has been tested
on many kinds of IDE DMA66 /100/133 HDDs, CD-ROMs and DVD-ROMs. No
matter your IDE device is an ATA hard disk or DVD-ROM, you all can plug it and
