Different poles of three decades development in microcontrollers’ domain

The contribution compares two realizations of hardware and software platforms from the microprocessor technique domain. The Intel 8080/8085 and Atmel AVR 8-bit microcontrollers are taken in occur. The proposed paper describes the differences between simple code implementation (e.g. stopwatch) for historical microcontrollers. The properties of implemented code, such as the total number of program memory occupation, the code velocity, and others will be presented as well.
