Synopsis:

The aim is to make students acquainted with the properties of microprocessor systems, make students familiar with on-chip peripherals, connect external circuit to the processor bus, and with implementation of the memory or I/O space address extension. Next, taught the students to make simple program in the assembly language, C language and combination of both. After completion of this subject student should be able to design and implement simpler microprocessor system including connection of necessary peripherals and software design.

Requirements:

Assume student will be able to implement combinatory circuit in different modifications and with different logic elements, multiplexers, memories and PLD and calculate its time delay. Student will be able to design and analyze logic of the sequential circuit and find its maximum clock frequency. He / she will know the timing of memories, function of basic sequential circuits, counters and shift registers.

Syllabus of lectures:

1. Fixed point and floating point arithmetic, implementations of arithmetic operations.

2. Basic structures of the microprocessor system, its history, current trends and classification.
