Agenda

• SATA Overview

– Summary, Features and Trend

– Merit and Solution

• SATA-IP Introduction

– Summary

– Application


What is SATA?

• Standard storage interface of HDD/SSD

– SATA1.0 released in year 2000, the latest standard

is SATA3.0.

• Improved from IDE (Parallel-ATA)– Cable（（（（from 80 line 46cm to flat narrow cable 1m））））

– High-speed (PATA: Max.133MB/s -> SATA: Max.600MByte/s)

– Jumper setting is not required anymore.


Jumper setting is

required to select

Master/Slave


Features of SATA device

• Popular

– Compatibility. Easy to replace.

– Commodity. Easy to buy.

• Low price

– 3.5”HDD 2TB is approximately 65USD

– 2.5“SSD 64GB is approximately 100USD

(Sep 2011, in Japanese market)

Merit of SATA adoption


• Huge non-volatile storage– GigaByte/TeraByte capacity.

• High-speed and Low cost– Several Megabyte per second Read/Write speed

– Mass‐‐‐‐produced goods

• Compatibility– Easy and quick to repair and recover, just replace.

– Your product lineup will be various with different capacity

storages

Just change storage capacity

to arrange various products

from high-end model to low cost model.


Solution for embedded system


• １１１１：：：：Use Existing SATA chip (ASSP)– Merit: Device cost

– Demerit：：：： Limitation of MOQ, support and fixed function

• ２２２２：：：：Use FPGA+SATA-IP core– Merit: Flexibility, support special usage such as RAID,

MOQ etc..

– Demerit：：：： Device cost (In case of SATA function only)

Conclusion:

If the system is simple function and the availability is acceptable,

ASSP may be better for you.

For other case, FPGA + SATA-IP core is best solution for you!!


What is SATA-IP?

• Implement SATA channel by MGT resource.

• IP-Core includes Link layer (and some part of Transport layer).

• Reference Design available for PHY layer and Transport layer.

IP-Core includes

Link layer

Reference Design provides

PHY layer design

Reference Design provides

Product Lineup

• Part number & supported devices

– SATA-IP001 :

• For Virtex-5LXT/Virtex-5SXT

– SATA-IP002 :

• For Virtex-5FXT

– SATA-IP003 :

• For Spartan-6LXT

– SATA-IP004 :

• For Virtex-6LXT


Supports both of Host and Device

• Single IP-Core supports both of Host (PC side) and

Device (Disk side).

– Switch between Host Core and Device Core by dev_host_n signal

input.

dev_host_n

= GND = VCC


Approved IP-Core by Xilinx

HDD performance

• SATA-IP Extracts HDD maximum performance

– Bottle neck exists not in SATA interface but in HDD internal.

– Transfer speed varies between outer and inner area of the disk.

HDD sequential access performance of SATA-IP


SSD performance

• More than 200MB/s transfer speed by the latest SSD.

• Achieves SSD specification performance.

– Best for high-speed large-capacity storage application.

Extracts maximum

performance from SSD


Free Bit-file for Evaluation (1)

• Serial communication with PC as Host side.

• Write/Read access to/from SATA device.

• Measure transmission speed.

Example of write transfer

•Set address, sector count and type of data pattern

•Measure transmission speed and display the result


Free Bit-file for Evaluation (2)

• Free bit-file for Evaluation on Xilinx FPGA boards.– ML505, ML506, ML605, SP605

• Downloadable from SATA-IP Web page.

Reference Design (Summary)

• EDK Project Design of Evaluation bit-file.

• Provide all source code (include firmware)

except IP core.

• It helps your development term reduce.– Check and study original reference design.

– Modify the reference and check operation

on real board to be final product step by step.

No risk to back to rebuild, able to develop for short term!
