* Microsoft 2006 Presentation + PaxDisk

Opinion

Aftermarket is Consumer concept => Life Cycle is about 6months~1year and Market size is big

Built-in Market is Industrial concept => Life cycle is over 5 years

Fujitsu-ten Memory Type Navigation, HDD Type Navigation (Fujitsu-ten is one of Toyota OEM Brand

Sanyo, Clarion also announce the SSD Navigation for making market difference


Japan Market 2, Built-in SSD Navigation

Honda’s New Solid State Drive(SSD) Navigation

Toyota has plan to use SSD for their Solaris OS Car PC


Auto-PC infortainment

Popular Car Navigator use Localization Map. So, Global business is limited.

Windows XP Based Auto-PC overcome the “Localization Limit”. H/W maker can survival unit only.

Recently Automotive Maker use PC based vehicle remote diagnosis before launching

It can be used to Car Telematics Service


Automotive HDD/SSD Market

Still HDD has good reliability.

But, SSD has more advantage. So, HDD will be replaced to SSD.

Intel Supper from ROI(Return of Investment) in the consumer area

Intel support Automotive Solutions ; the first is “ATOM Processor”


intel Automotive Base Board / Platform Diagram

* intel Automotive information

Intel use ATOM processor for Built-in & After Market and ATOM support Industrial Grade

Intel use Xilinx FPGA for South Bridge. It has various flexibility.

SSD Controller has CPU and ROM, RAM and buffer

NAND Interface need to correct ECC logic.

ARM CORTEX-R4 has Fault Tolerant Scheme.

In the silicon devices, stray radiation and other effects can cause system’s corruption.

Fault Tolerant technology is necessary.

We need more detailed study for the temperature.


A valuable lesson can be learned from it.

1. Navigation & Black Box Recall Problem

2. Weak Controller issue

3. B-grade NAND Flash issue

4. Weak Test Methodology

5. Piracy SD Card

???

1. No Price Room for the Good SD Card

2. Increasing Accident Raito while driving a car

3. End-user’s wrong awareness for NAND flash media

SD Card is industry Standard. But, What is SD Association’s Role ?

Many Customer supper from broken SD Card in the Navigation. Is SSD different ?

PaxDisk Support the Military & AeroSpace Applications.

PaxDisk is now focused to Radiation-Tolerance Space SSD Technology.
