Operating System for Embedded Applications Control
Kolarík, Tomáš ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
This thesis deals with selection of operating system for embedded control unit of steam sterilizer with color touch screen. Theoretical part of the thesis deals with the architecture of embedded systems and operating systems with focus on process management. In addition, the thesis deals with a device for which the operating system is selected, the reason for its implementation, advantages and disadvantages in the control system. The thesis also contains categorization of operating systems by way of use. Of these, two open source operating systems eCos and FreeRTOS are described more thoroughly. The code of FreeRTOS was modified from GCC compiler to IAR compiler. The last part of the thesis describes architecture and functionality of the created demo application. Using the touch screen and color display, the application enables drawing of color schemes, which can be transferred to a computer using serial communication.
Discrete Simulation in Java: Process Scheduling
Skočovský, Peter ; Kočí, Radek (referee) ; Martinek, David (advisor)
This thesis deals with process scheduling implementation for discrete simulation in Java. Two approaches are considered: process implementation using threads and process implementation without threads. Main problem of using threads was to ensure cooperative switching. Processes implemented without threads are divided into atomic parts and suspend can be performed only between these parts. Test results show that implementation using threads is considerably slower and consumes more memory.
