The development of an operating system in LYaPAS

The development of OS LYaPAS for writing and executing programs in LYaPAS is described. Currently the creation of OS LYaPAS is in the stage of kernel development. The following functions are implemented: message output to screen, device-controllers initialization, interrupts handling, working with timer and keyboard, multitasking. Multitasking is demonstrated by a few parallel processes that can be suspended and restored with a key press. The further step in the development is the creation of a file system and memory management modules.
