Arasan Chip Systems Releases MIPI UniPro(sm) Software Stack Extending Its Total IP Solution

Accelerate System Design With UniPro Software Stack

SAN JOSE, Calif. -- April 16, 2009  -- Arasan Chip Systems, Inc. (``Arasan''), a leader in Intellectual Property (IP) solutions - IP cores, Verification IP (VIP), Software Drivers and Stacks and Hardware Solutions, announced the immediate availability of the Mobile Industry Processor Interface (MIPI(r)) UniPro Software Stack, a layered, kernel-level stack that eases the integration of UniPro into mobile platforms. The UniPro Stack complements Arasan's recently announced UniPro IP, thereby continuing Arasan's commitment to offering a ``Total IP Solution'' to customers.

Arasan's UniPro Stack is implemented as a linux kernel module, but its modular architecture eases porting effort to other operating systems. The Stack is compliant with the UniPro v1.1 specification. The functionality supported includes master Direct Memory Access (DMA), end-to-end (E-2-E) flow control and Quality of Service (QoS) for data transfers. The Stack consists of the following five layers: a) Driver module; b) UniPro protocol layer; c) Hardware interface abstraction layer; d) OS abstraction layer; e) Hardware interface layer. This modular architecture makes it easy to port, extend and incorporate Arasan's UniPro solution into different OS's and hardware platforms.

The application accesses the UniPro Stack through a simple API interface. The Stack handles initialization and configuration of the underlying hardware. Integrating the Arasan IP and Stack enables mobile chipset developers to broaden their market by seamlessly connecting with other UniPro compliant components.

``MIPI's Unipro protocol plays a vital role in standardizing high performance interconnect in mobile platforms and thereby accelerates the development and integration of innovative functions'' said Atul Garg, Director of Software Engineering at Arasan. ``Arasan's proven UniPro Stack and IP provide a risk-free integration path that enables a rich, inter-operable ecosystem benefiting mobile chipset, platform and application development''.

Arasan provides a ``Total IP Solution'' for UniPro including but not limited to the IP core and software stack. The Stack includes source code, documentation and integration support.

Availability

The UniPro Software Stack is available immediately for integration into mobile platforms. For additional information on Arasan's UniPro Software Stack or other MIPI solutions, refer to http://www.arasan.com/totalmipi.
