    7. Objectives, learning outcomes and obtained knowledge Wide inside is given of the computer system architectures, high performance microcontroller architectures and their building blocks. Convectional architectures are analyzed then special architectures (ARM, DSP, network and graphic processors, GPGPU) are dealt with and compared with the SoC devices with soft and hard processors. Methods increasing the performance, security and reliability, decreasing power consumption are treated. Mechanical, electrical and logical aspects of bus systems connecting parts of control systems are treated in detail. Diagnostic methods of WEB, mobile, etc. based control systems are also introduced.

    9. Method of instruction The course consists of lectures and practices, which are alternating during the semester. The lectures mainly contain the theoretical background and case studies are presented in practices.
    10. Assessment
    In lecture term:
    An in-class term test
    In examination period:
    Written exam

    The requisite of the mid-term signature is to attend at the in-class term test and have at least satisfactory (minimum 45%) result. The requisite of attending at an exam is having the mid-term signature. The credits can be obtained by reaching at least satisfactory result at the exam. The final grade consists of the results of the in-class mid-term test (30%) and the exam (70%).

    11. Recaps The in-class term test can be repeated once during the semester and once during the repeat period in accordance with the Code of Studies and Exams (CSE). The possibility of a second replacement can only be provided in justified cases, after individual consultation.
    12. Consultations Upon request, appointed with the lecturer.
