SLIM^TM

Mass Storage Interface

SD/MMC/CE-ATA

NAND

With this architecture, connecting a device using Antioch to a

PC through USB does not disturb any of the functions of the

device, which can still access Mass storage at the same time

the PC is synchronizing with the main processor.

3.0 Functional Overview

3.1The SLIM™ architecture

The Simultaneous Link to Independent Multimedia (SLIM)

architecture allows three different interfaces (the P-port, the

S-port and the U-port) to connect to one-another indepen-

dently.

The SLIM architecture enables new usage models, in which a

PC can access a Mass storage device independent of the

main processor, or enumerate access to both the mass

storage and the main processor at the same time.
