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.
