In the electronics world embedded systems are everywhere, many of which are based on microcontrollers. Throughout the design cycle of such systems, the microcontroller’s performance is always critical for the project’s success. But what does performance represent for a microcontroller and how can we measure it? This paper presents an analysis of different test algorithms executed on a series of 8-bit microcontrollers. The test algorithms are represented by test sequences that are carefully designed in order to reflect real life scenarios. This study takes into consideration two performance aspects: the execution time, also known as time performance and the power consumption, also known as power performance. At the end of this paper there is a performance comparison between multiple 8-bit microcontrollers.
This project presents a concept of monitoring the most important parameters of a vehicle. The main purpose of the parameter monitoring system is to announce the driver when one of them exceeds the normal operating values. The system contains secondary devices and a development board. With this system the parameters are taken from the car's computer and displayed for the driver on a screen without disturbing his attention in traffic. The most important thing about this system is that it can display parameters that are not found on the car's dashboard.
This project is based on a 3D LED cube with dimensions of 5x5x5. Besides the physical realization of the cube, a code has been developed with which all the letters of the alphabet can be displayed, also all the numbers and various 3D animations. This 3D LED cube can be used for road signs, warning signs for trucks carrying dangerous products or as a simple commercial advertisement.
The most usual performance evaluation for a CPU(Central Processing Unit) is the amount of time needed to execute a certain algorithm. In a similar way, this concept can be extended to microcontrollers. This paper presents an analysis of different CPU load algorithms executed on Microchip 8-bit microcontrollers. This analysis is based mainly on execution time measurements. Based on these details, original contributions to this paper are: the design of some CPU load algorithms, the developing of the software for the microcontrollers used in the experiments and the experimental results regarding the presented algorithms.

This paper presents the concept of a universal control system for automation of small test setups. The main purpose is to control the environment in which the electronic component is being tested. The system has two device types: a master device and multiple slave devices. In this control system the devices are able to communicate with each other and are able to monitor and control specific tasks or actions required in the test flow. The system can be configured using a computer application based on text input.
