About the Laboratory:
The Microprocessor laboratory is one of the main laboratories in the department where students understand the architecture of the microprocessors leading the students to the level of practically programming this processer through various programs. These programs are then included in microprocessors reading using several experiments. In this regard, the sequence of experiments was taken into consideration to be inline with the theoretical material taken by the student in terms of the sequence of information. The main prototype which is currently adopted in the laboratory is (Microprocessor -8086) and the near future ambition is to add the prototype (Microprocessor -8386). In addition, in this lab, lectures are given to the students of the third year for all the branches (Control, Mechatronics, Computers, and Medical Systems) in a total of 8 hours per week and an average of 22 students for each class.
The Vision and the Objectives of the laboratory
The Microprocessor Laboratory aims at providing the students with the basic principles of the microprocessor subject in terms of learning its programming and implementation on the laboratory’s devices using a set of laboratory experiments. Therefore, students are introduced to the basic concepts of microprocessors in order to prepare engineers with the required knowledge and competence to deal with these microprocessors.
