USB 3.0 Device Software Stack
Universal Serial Bus continues to be the dominant interface in the PC, Mobile, Consumer Electronics and Communication Markets. To address the increased demand placed on data transfer speeds with high-definition video content, terra-byte storage devices, high megapixel digital cameras, multi-gigabyte mobile phones and portable media players, the USB 3.0 specification was created that allows speeds up to 5Gbps.
The USB 3.0 Device Stack is Arasan’s latest development that enables designers in the PC, mobile, consumer and communication markets to establish communication between a USB 3.0 compliant devices and USB hosts. USB 3.0 compliant devices include external hard drives, digital video cameras, mobile phone cameras, digital still cameras and others. Arasan provides designers with a comprehensive, USB 3.0 Device Stack that fully conforms to USB 3.0 v1.0 specifications and allows existing and new developments to easily migrate
to the USB 3.0 interface. It accelerates time to market by allowing easy integration of USB
3.0 device IPs into your system.
The Arasan USB device stack is written in ANSI C code making it highly portable across multiple platforms.It provides an OS and HW independent architecture with wrappers around OS and hardware abstruction layer. It supports USB control, bulk, interrupt and isochronous transfer modes.
The Arasan USB 3.0 Device Stack is available with optional Mass Storage and/or Communication class drivers.
