Tancher Garden Deep Integration (TGDI) – the Modular Approach in System Integration Solutions Based on Wireless Mobile Terminals

Tancher has the significant experience in the mobile devices development which allows to develop its own approach in creating new mobile solutions.

It is possible to use modular design if there is a standard way to connect any module to the any platform and the software, both drivers and applications, works under every platform.

In this case the customer only has to select the desired platform, set of modules and the device appearance. The rest is to redesign PCB as needed to fit the customer’s form-factor greatly reducing the development time and expenses.

The Tancher company has conducted the modern market analysis and proposes three platforms:

Tancher BIRCH platform is intended for the low price niche. It is based on the simple CPU and has limited resources. That platform was used for the CYBIKO XTREME, that worked with CyOS operating system. (see detailed info on www.tancher.com/TGDI_eng.htm)

Tancher MAPL platform: is intended to the medium price niche devices. It uses ARM7 CPU and has significantly larger functionality. It works with OST operating system. The platform was used in the specialized GSM/GPRS communicator projects for the Planet Halo (USA) и AT&T Wireless Systems (USA). The platform supports a wide range of modules. (see detailed info on www.tancher.com/TGDI_eng.htm)

Tancher OAK platform is the enterprise platform. It uses the XScale CPU and has the leading edge functionality. Works with both Windows CE 5.0 and OST. The platform is intended for Hi-End devices and provides maximum number for modules. It was used to the premium class smartphone design for the Mago Mobile company.

The modular approach in the software is the usual practice widely used almost from the very beginning of the computer programming. In both Windows CE and OST (Operating System by Tancher) this approach was used to full extent providing glut great flexibility and porting ease.

OS functions are available with well documented and intuitive C++ interface.

It is possible to develop additional interpreted language modules to run, for example, Java or Python applications and scripts. The component structure of the OST allows great scalability and flexibility optimizing system resource consumption to cover the widest range of application.

Other application and services could be developed easily.

It should be specially noted that OST is initially designed as operating system for the mobile devices using specific design concepts and resource saving technologies, that somewhat complicates software design providing better performance and application flexibility. As the result, OST provides best characteristics with limited resources, for example, improving battery life and reducing necessary memory footprint and CPU power consumption.

Conclusion.

The constantly changing world bears new technologies every few months, which, in turn, rises new tasks and increases hardware manufacturers competition. Existing mobile devices usually does not allow any significant modernization. Usual (non-modular) approach does not provide sufficient cost effectiveness. Modular design greatly reduces development costs and time, unit price and risks. The advantage of the modular design is most essential with medium and small production batches and pronounced device specific such as limited and soecial functionality, especially when the unit and development price is critical.
