Agenda
  • Update
  • Purpose
  • Overview
  • Market Impact
  • Proposal Plan
  • Technical Overview
  • Commands
  • Command Example for SD Card
  • Comparison with IBM proposal
  • Goal

3
Update from Last meeting
  • Consider the modification with IBM Discussion
    with IBM Clarification for Both Proposals
  • Put Overview Modify the Document
  • Decrease commands Delete D5 and D6

4
Proposal Purpose
  • Define the Commands for ATA adopter for Small
    Memory Cards
  • Not only for SD ,but also SD-IO, SmartMedia,
    Memory Stick
  • Common PC Card ATA interface for above Small PC
    card.
  • Enable the Generic Driver for SD card /ATA as
    Storage devices

5
Proposal Overview Expand the IDE/ATA Commands
for PC Card Adopter
  • Define New Command on ATA Reserved Area (D1 to
    D4)
  • D1 Switch to Adopter command mode
  • D2-D4Assign to Media card (Small Memory cards)
  • Expand the definition of the ATA IDENTIFY DEVICE
    command on 176-191 word. Range

6
Market Impact ATA PC Card Adopter for SD
  • Command pass through the PC Card ATA
  • Working as Storage Device on Current System
  • SD Functions are Enabled by SD command pass
    through (NOT by CPRM)
  • Common ATA Interface Controller, Drivers
  • Common SD Card Adopter for Note-PC through PC
    Card Slot

This Proposal
Common I/F
7
Other Possible Solutions for ATA Adopters by
this proposal
Media Card Small Memory Card
  • SD-IO Non security
  • SmartMedia Serial ID based Security(Non-CPRM)
  • Memory Stick Magic Gate(Non-CPRM) /IO
  • Others

Camera
8
Proposal Plan
  • Design Implementation for ATA Adopter
  • Working with T13 for D1-D4 Assignment
  • Working Other Organizations prior D1-D4
    assignment
  • PCMCIA/JEIDA for PC card ATA
  • SDA for SD Based D1-D4 Usage by SD Command ATA
    Extension document
  • Other Cards Each Groups

9
Technical Overview
  • Define Commands D1 to D4 in ATA command
    reserved area.
  • D1 Check Card Extension Commands
  • D2-D4 Assigned by Each Memory card
  • D2-D4 for SD are descried by SD ATA Command
    Extension
  • Expand the definition of the ATA IDENTIFY DEVICE
    command on 176-191 word.

Comparison with IBM proposal
15
Application Based Commands ATA Storage vs. ATA
Adopters
IBM Proposal
CPRM
This Proposal (For PC Card )
HDD/CF
SD Memory
SD Specification
SD IO
16
Why the D1-D4 Command is required?
  • SD IO functionality is needed on the same IF.
  • SD Command is expanding.
  • Application can operate with SD API.
  • Legacy Card support
  • Possibility for Other Memory cards (SmartMedia,
    Memory Stick, Others)

17
Example for SD Application
  • Define SD Commands D1 to D4 in ATA command
    reserved area.
  • D1 Check SD Extension Commands
  • D2 SD Header Command
  • D3 SD Execute Command
  • D4 Retrieve Response Command
  • Expand the definition of the ATA IDENTIFY DEVICE
    command on 176-191 word.

18
Goal
  • Define the ATA Command Extension for Media Card
    (SD and Others ) by D1-D4
  • Initiate the Media Card Application on PC card
    Slot
  • Common Switching Mechanism in PC Card ATA
  • Common interface for other Media cards
  • Do command conflict for Current and Future
    ATA/IDE
  • SD Command Extensions in SDA

19
Conclusions
  • Purpose PC Card ATA adopters for Media Card
  • D1-D4 ATA Command Are requirement
  • D1 For Switching the Mode
  • D2-D4 Assign to Media Card commends
  • Focus on Different Application from IBM Proposal
  • Independent from CPRM technologies
