2.3

USB

Accordo2 has one USB HS host interface and one Dual role USB HS, both with embedded

PHY, allowing to efficiently connect to mass storage devices, as well as portable devices

(phones, pads). Along with USB connectivity, Accordo2 fully supports USB charger

specification. The controller supports HS 480-Mbps using an EHCI Host Controller, as well

as FS and LS modes through an integrated OHCI interface.

2.4

Sound subsystem

Accordo2 implements a sound subsystem which allows to efficiently handle sound

processing tasks, such as spatialization and equalizer, without loading the main CPU with

interrupt intensive tasks.
