Synopsys Inc. has announced the release of its DesignWare Wireless USB host and dual-role device (DRD) intellectual property (IP) based on the Wireless USB specification from USB-IF.

The DesignWare Wireless USB host is based on the Wireless Host Controller Interface (WHCI) specification and is designed for applications like PC chipsets, STBs, personal video recorders, DVD players and DTVs.

Designing to the WHCI specification enables system makers to build applications on standard WHCI drivers to save months of software driver development. To enable broad driver compatibility, the DesignWare Wireless USB DRD uses the same host register set as the host. The DRD can be used in callphones, PMPs, digital cameras and printers, for example, to exchange videos or music wirelessly.

The DesignWare Host and DRD IP are built to suit portable electronics apps that demand high power conservation and device interoperability. Dual power rails allow the designs to shut down power to sections that are not in use, resulting in additional power savings over clock gating. The IP's GUI enables designers to rapidly configure the IP to use the smallest area for the required features, minimizing silicon cost and power consumption.

Moreover, the DesignWare Host and DRD IP feature a flexible, firmware-programmable design that can be used for post-silicon feature additions and bug fixes. This reduces the likelihood of a chip respin and saves mask costs.

The full-featured, synthesizable DesignWare Wireless USB host and DRD are compatible with WiMedia Alliance's UWB Common Radio Platform. The IP includes the digital controller logic required to integrate certified Wireless USB IP into SoCs. The IP also features a standard WiMedia MAC-PHY interface for rapid integration with standard UWB PHYs. At present, Synopsys has been continuously testing the IP with UWB PHYs from Alereon and Realtek.

The DesignWare Wireless USB device, host and DRD IP are already available.
