CyOS is a full multitasking operational system.
CyOS main features:
The CyOS functionally represents a multitask
environment with an interprocess interaction. It includes peripherals access, a
file system, a graphics support, sound, dynamic loaded units, applications
archives, and means of information transmission via radio channels.
- Preemptive multitasking
- Memory management system
- Graphics system
- File system
- Dynamic module loading
- Dynamic linking
- Means of interdevice communication
CyOS handles a task comprising one or several threads, or processes executed in
pseudo-parallel as in displaced multitasking. The synchronization of threads is
carried out by Mutex, Flag, and Flagex. A thread can be in the process of
fulfillment, or queuing for fulfillment, or hibernating ahead of an event as in
The sending of messages addressed to processes on other devices represents the
network exchange. The transmission is carried out through a radio channel with
automatic assembly/disassembly of packages and a notice of delivery.
Application are located on a file device as archives comprising several files.
An archive includes a module under execution, resources files, and application
description files in the oblate sort. When an application is started from the
archive, the system extracts and unpacks the module under execution in its
The application usually creates an object of the main process, bans outloading
of the module from the memory, and returns the control to OS. After the
initialization of an internal state, the created process transfers to the
expectation of messages. The processor time is not spent on it. When a message
arrives, the process revives, processes the message, and returns to the
Dynamic linking allows storing of frequently used components in separate
executable modules, thus saves both long-storing device memory and RAM. CYBIKO
gives a standard set of such modules.
System Pack is a set of standard interface modules and dynamic libraries. The
main goal of System Pack is to provide uniform user interface in all
There are currently seven libraries in the System Pack: Settings, Locales,
Finder, Servers, Power Saver, CyWin, and Custom Dialogs. These libraries are
intended to help programming in such features as communication with people,
running applications, storage of various configuration data, handling different
locales, management of system power, and graphics user interface.
All important system configuration settings are contained in specially organized
storage. You can easily access or change these settings through the Settings
library. If you need to display the current time for the user, you can take
advantage of the Locales library because time is different for different
countries. Using the Finder, you can determine how many people are currently
around you and find out their nicknames and other data through a few function
calls. Almost every application requires various data windows such as dialog
boxes, forms, menus, and lists to display information to the user in a suitable
form. The CyWin library can help you solve these tasks.
Service applications included in the System Pack provide a basic set of
necessary user functions. They allow easy graphical management of programs on
your Cybiko computer, store information about you and your friends, search for people,
configure systems, and so on.
