Lecture topics in details:

Architectural basics (3 weeks)
Central units of digital systems: architectural comparison of microprocessors and microcontrollers, basic rules for architecture selection. 8/16/32 bit systems, CISC/RISC architecture. Importance of architecture selection, and its effect on system-wide properties (speed, bit handling, fractional numbers, internal memory, register banks). Detailed description of microcontroller architectures through concrete microcontrollers (8051, Cortex M4). Programming model, interrupt subsystem and priority handling.

Low level software development (4,5 weeks)
Low level programming using assembly and C languages. The process of software development. Programming languages, development for desktop PC-s and embedded systems. Software development model, the properties of the instruction set. Typical development environments (SiLabs, Keil, STM), the structure of the firmware (configuration, startup code, interrupt handling.) Assembly inserts and subroutines.

Integrated peripherals of microcontrollers (3 weeks)
Clock generators (internal, external, PLL circuits), reset and watchdog circuits. Memories (OTP ROM, flash, RAM, EEPROM). Timer and counter units (working modes, QEP, capture module, PWM). Integrated asynchronous and synchronous communication units and protocols (SCI, SPI, I2C, CAN). Digital input and output modules, the internal design of microcontroller ports. Analog input and output modules.  
Connecting external peripherals to microcontrollers, typical connections (2,5 weeks)
External clock generators, external memory connections (serial, parallel, using internal CSUNIT-s, wait cycle problems). Analog and digital IO connection problems, special peripherals (RTC, programmed logic, ASIC circuits). Signal conversion for physical levels (RS232, RS485, CAN). EMC and decoupling.

Basic concepts and steps of hardware development (1 week)
Using CAD systems for hardware development: schematic, simulation, PCB design systems and the most important features of them. Form and content of a hardware plan, technology considerations (through hole and surface mounted parts, number of PCB layers, soldering technology, etc.). EMC considerations. Wakeup, programmer and test interfaces. Importance of in-circuit programming. Custom and standardized (JTAG) interfaces. Internal and external bootloaders, firmware update.

The requisite of the mid-term signature is to attend at the in-class term test and have at least satisfactory 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 grade consists of two parts: the grade of the mid-term test (25%) and the grade of the exam (75%).
