Functional Overview
The SLIM Architecture
The SLIM architecture enables three different interfaces (P-port, S-port, and U-port) to connect to each other independently.
With this architecture, a device using Arroyo is connected to a PC through a USB, without disturbing any of the device functions. The device can still access mass storage when the PC is synchronizing with the main processor.
