Stack Complements USB OTG Controllers

Fine tuned to accommodate small footprint, power efficient devices, such as digital cameras, PDAs, mobile phones and other applications where battery life and memory are major concerns, this new Universal Serial Bus (USB) software stack is designed to complement the company's Inventra line of On-The-Go (OTG) controllers—the Inventra Dual Role controllers are designed to support a device's host and function capabilities and to swap these roles dynamically. The USB OTG software stack detects the connection of a function or a host device and switches automatically to the appropriate mode. For OTG-to-OTG connections, the stack supports the Host Negotiation Protocol (HNP) that allows the software to respond to requests for a role change and enables the device to switch seamlessly between modes. A scheduling algorithm has also been developed for distributing bandwidth among a limited set of connected devices while reducing the stack's footprint to a fraction of that of a typical re-purposed PC solution.
