Tancher has designed and developed a special proprietary operating system free of all currently known system disadvantages. The system is called OST (Operating System by Tancher) and it is being licensed by Tancher clients from custom-built portable devices.

OST is a scalable and adjustable operating system that can be easily used for custom applications. See the picture to understand its structure.

HAL is the only part of the system that interacts with the hardware. The core uses HAL to provide basic functionality of the protocols and utilities using limited software interfaces. The core implements such basic functionality as protocol stacks, power control, including standby-wakeup transitions, timers, streams, pipes, and additional libraries like UI, compression, codecs, multimedia, etc. The OS functions are available through the 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 by optimizing system resource consumption to cover the widest range of application.

The following OST modules are currently available:

Drivers

• Serial (UART)
• LCD
• Audio over PWM
• Audio AC97
• Highlighting/indication with PWM (brightness control and transitions)
• Keyboard
• NAND-FLASH mass storage
• Filesystem
• Real Time Clock
• Battery driver (charger)
• ADC
• GSM/GPRS module driver
• Bluetooth module driver
• USB Client
• Touch Screen

Protocols

• PPP
• TCP/IP
• BCSP
• HTTP, HTTPS
• SMTP
• POP3
• SSL
• Wireless village

Libraries

• Data compression (bzip and others)
• 2D Graphics including various fonts and image formats, including animated gif, png and jpeg.
• GUI
• AMR, AMR2 codec
• Phone services (calls, SMS, MMS, SIM services, etc.)

Applications

• Desktop
• Voice Dialer
• E-mail with SMS
• Multiprotocol Instant Messenger
• Organizer
• Address Book integrated with other application, such as phone or email.
• Settings
• Web-browser with popular xHtml and CSS subset

Other application and services can easily be developed.

It should be specially noted that OST was designed as an operating system for mobile devices using specific design concepts and resource saving technologies. As a result, OST provides superior characteristics with limited resources; for example, improving battery life and reducing the necessary memory footprint and CPU power consumption.
