Education

BS, MS, Technical University of Cluj-Napoca (Romania); Ph.D., Washington State University

Bio

Professor Dorin Patru teaches digital and computer, circuits and systems courses. He joined the department in fall 2002. He received a B.S. and M.S. in Electrical Engineering from the Technical University of Cluj-Napoca, Romania, and a Ph.D. in Electrical Engineering from Washington State University.

Dr. Patru, his colleagues, and his research assistants are currently pursuing both applied and basic research in the areas of custom digital systems and digital computer systems. The applied research focuses on aerospace systems (cryogenic image sensors and cubesats), and automated test equipment for photonic integrated circuits. The basic research focuses on novel and efficient digital data processing architectures.

Currently Teaching

EEEE-220
Digital Systems II
3 Credits
In the first part, the course covers the design of digital systems using a hardware description language. In the second part, it covers the design of large digital systems using the computer design methodology, and culminates with the design of a reduced instruction set central processing unit, associated memory and input/output peripherals. The course focuses on the design, capture, simulation, and verification of major hardware components such as: the datapath, the control unit, the central processing unit, the system memory, and the I/O modules. The lab sessions enforce and complement the concepts and design principles exposed in the lecture through the use of CAD tools and emulation in a commercial FPGA. This course assumes a background in C programming.
EEEE-499
Co-op
0 Credits
One semester of paid work experience in electrical engineering.
EEEE-521
Design of Computer Systems
3 Credits
The purpose of this course is to expose students to the design of single and multicore computer systems. The lectures cover the design principles of instructions set architectures, non-pipelined data paths, control unit, pipelined data paths, hierarchical memory (cache), and multicore processors. The design constraints and the interdependencies of computer systems building blocks are being presented. The operation of single core, multicore, vector, VLIW, and EPIC processors is explained. In the first half of the semester, the lab projects enforce the material presented in the lectures through the design and physical emulation of a pipelined, single core processor. This is then being used in the second half of the semester to create a multicore computer system. The importance of hardware & software co-design is emphasized throughout the course.

Students are further required to choose a research topic in the area of computer systems, perform bibliographic research, and write a research paper following a prescribed format.
EEEE-721
Advanced Topics in Computer System Design
3 Credits
In this course the student is introduced to advanced topics in computer systems design. It is expected that the student is already familiar with the design of a non-pipelined, single core processor. The lectures cover instruction level parallelism, limits of the former, thread level parallelism, multicore processors, optimized hierarchical memory design, storage systems, and large-scale multiprocessors for scientific applications. The projects reinforce the lectures material, by offering a hands-on development and system level simulation experience.
