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

(PRWEB) January 5, 2006

A wide range of gadgets appeared on the market covering a huge variety of functions staring from remote controls and ending up with PDAs very close to PCs in functionality. Mobile devices entered daily life which leads to a need to integrate them seamlessly into all the human activity areas. WiFi, Bluetooth, cellular networks; with a constant market price reduction all these technologies have become a usual instrument for everyone.

Every mobile device is created to solve a set of predefined tasks. From the clients (who orders the design) or end users point of view it is very important that the device solves the necessary tasks with minimal expenses. In this case we do not consider the problem of the user characteristics or the device status. Some times the design itself or the product positioning effects the price.

Summarizing, it can be said that when customer comes to a need of proper equipment, he or she has to solve a difficult optimization task choosing from a quite small amount of variants. If we are solving a standard task, the solution of which can be applied not only for the situation involved but also can be required by other customers, the situation looks acceptable. But in case of a specific, new solution (given the market does not offer such a device) situation becomes complicated and a compromise shall be found.

Tanchers modular design approach.

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 customers form-factor greatly reducing the development time and expenses.

The Tancher company has conducted the modern market analysis and proposes as a part of proposed TGDI approach, 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. There is a port of OST (Operating System by Tancher) for it and the wide set of modules and application software.

Tancher MAPL platform: is intended to the medium price niche devices. I 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, what is clearly seen comparing two above mentioned projects. (find detailed info and pictures on http://www.tancher.com/TGDI_eng.htm )

Tancher OAK platform is the enterprise platform. It uses the Intel XScale 624MHz CPU and has the leading edge functionality. Works with both Windows CE 5.0 (Windows Mobile 2005 shell) 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, fro 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.

(Please find detailed info about OST module avialable on http://www.tancher.com/TGDI_eng.htm)

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.


Existing mobile devices usually does not allow any significant modernization. As the result, there is most often no effectively suitable devices on the market to fit many real automation tasks. Usual (non-modular) approach does not provide sufficient cost effectiveness. Modular design greatly reduces development costs and time, unit price and risks. Using this approach development of the specific devices it is often most effective solution. 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. Following are the examples of the domains where such requirements are likely to appear:
