Bridging of SCSI to SATA and Implementation of a
SATA Controller using Virtex5 (Electronics Project)
Companies and authorities of today often handle large amount of data, not unusually with a restricted content
FPGA design
which should be kept secret from outsiders. One way of

From Timing Diagrams
this a hardware solution is ideal since it can be independent, fast enough, and easily added to already existing systems.
This report is a starting point to achieve this with two of

the most common mass storage standards SATA and
SCSI in focus. It is based on the task to develop a FPGA based SATA controller and investigate the possibility to
”speak” SCSI with SATA devices.

The working process has involved theoretical studies, system design, test driven development using simulations and hardware tests and technical investigation.
The study resulted in a SCSItoSATA translation investigation pointing out difficulties and presenting a translation model. A SATA host was also implemented in VHDL on a Virtex5 FPGA that can execute a number of SATA commands on different devices. Simulations performed shows that the total latency reaches one μs/32 bits in the
SATA host and that should not be much of a problem for most applications in a
