- 5. CS/ECE 552: Introduction to Computer Architecture, University of Wisconsin Where does the course t in your curriculum? This is taken by juniors, seniors, and beginning graduate students in computer science and computer engineering. Prerequisites include courses that cover assembly language and logic design. This course is a (recommended) prerequisite for a graduate course on advanced computer architecture. Approximately 60 students take the course per offering; it is offered two times per year (once each semester). Assessment Assessment is a combination of homework, class project, and exams. There are typically six homework assignments. The project is a detailed implementation of a 16-bit computer for an example instruction set. The project requires both an unpipelined as well as a pipelined implementation and typically takes close to a hundred hours of work to complete successfully. The project and homeworks are typically done by teams of 2 students. There is a midterm exam and a final exam, each of which is typically 2 hours long. 20% Homework 25% Project 25% Midterm 25% Final 5% Class participation Tools Mentor, ModelSim, WISC-SP08 Simulator-debugger, cacheSim, wsrun.pl Knowledge Area Total Hours of Coverage Architecture and Organization (AR) 39

This is a senior-level course in the computer science curriculum for computer engineering students interested in computer design. Assessment Examinations, homeworks, and hands-on laboratory exercises.The class will have two mid-terms and no final. The class will have two long homework assignments. Labs: The centerpiece of the class is a set of computer architecture lab assignments based on RISC-V processors implemented in the Chisel hardware description language. Three architecture simulation labs are the focus of the class: Lab 1 (directed, open-ended) covers static pipelined CPUs. Lab 2 covers the memory hierarchy. Lab 3 covers dynamically-scheduled CPUs. The heart of each lab is the open-ended section. This section lists a set of computer architecture project topics that are a good fit to a 3-week work schedule. Students pick one of the open-ended projects, and focus on doing the best job possible during the allotted time period. Academic Honesty: Copying all or part of another person's work, or using reference material not specifically allowed, are forms of cheating and will not be tolerated. A student involved in an incident of cheating will be assigned an F grade or a 'zero' grade to the subject work Knowledge Area Total Hours of Coverage Architecture and Organization (AR) 33

COA course contents lie on the intersection of hardware and software and tightly links to the operating system, compiler/assembler, and programming, the design of hardware system can affect programming strategy and execution efciency of programs. Principles for designing the curriculum (1). The curriculum must periodically update and adjust its topics and contents (2). Hardware is tightly linked with software concepts and knowledge - so understand hardware from the perspective of programmers. (3). The course experiments should lead students make use of what they have learned. - course experiments should be helpful for students to develop their computer skills, (4). Include professional skills as an integral part of the curriculum. -Introduce concrete examples : American Patriot Missile failure to intercept an incoming Iraqi Scud missile Intel Pentium Process Floating-Point Number Bug ChunfengYuan;Yihua Huang; Zhesheng Zhang; Guihai Chen;Wanchun Dou, "Improvements on Teaching Methods and Contents for the "Computer Organization and Architecture" Curriculum," Scalable Computing and Communications; Eighth International Conference on Embedded Computing, 2009.

The curriculum refers to not only the hardware and the Instruction Set Architecture design but also software design for operating systems, compilers and programming. eg how oat no is stored in hardware Begin from the programming perspective; stress the relationship between hardware and software; place emphasis on CPU design; and aim to enhance system performance (1). Based on approach, high-level programming language-> assembly language ->machine code-> instructions CPU design, (2). In regard to CPU design contents, design of the pipelined CPU and other advanced technology. Based on a progressive order the IAS machines CPU ->bus-driven CPU ->single- cycle CPU ->multi-cycle CPU ->basic pipelined CPU-> advanced pipelined CPU, using MIPS and Pentium 4 processors as blueprint, 3. interaction between hardware and software, exception and interruption, memory access, and I/O access into the execution process of instructions. 4. Incorporating the pipelining of a CPU, we explain how to optimize compilers. Experiments and Results Authors emphasize on designing a pipelined CPU based on the strategy: begin with ISA simulator, then functional components design, then designing a single-cycle CPU, and nally pipelined CPU design. Altera DE2 experiment toolkits that allow students to use hardware description language and FPGA to conduct their CPU design experiments. The results have shown that the majority of students can complete their CPU design projects either a single-cycle CPU or a multi-cycle CPU, and some of them can accomplish their design for a 5-segment pipelined CPU.

Nikolic, B.; Radivojevic, Z.; Djordjevic, J.; Milutinovic,V., "A Survey and Evaluation of Simulators Suitable for Teaching Courses in Computer Architecture and Organization," Education, IEEE Transactions on , vol.52, no.4, pp.449,458, Nov. 2009 This paper attempts to give a survey of simulators suitable for teaching courses in computer architecture and organization.
- 18. Generally, these simulators can be separated into two major groups The rst group contains the appropriate tools and necessary methods to enable the user rst to build specic computer system congurations and then to simulate them. This type of simulator implies ve-step procedure in which a user: 1. selects components from the library; 2. places selected components onto the working panel; 3. connects the selected component with other ones in order to create a new component; 4. creates an interface for the created new component; and 5. tests the created component. The most representative simulators from this group are: HASE, ISE Design Suite, JHDL, Logisim, M5, Quartus II, Simics, SMOK, and Virtual Vulcan. The second group of simulators contains appropriate tools that enable the user to simulate already created systems. This type of simulator implies the ve step procedure in which a user: 1. initializes the simulator with default options; 2. species the test conguration; 3. creates test vectors and diagrams to be observed; 4. carries out the simulation; and 5. analyzes test results for the specied test conguration. The most representative simulators from this group used in the evaluation are: ANT, CASLE, CCSTUDIO, CodeWar- rior, CPU Sim, DigLC2, DLXview, Easy CPU, EDCOMP, ESCAPE, FastCache, HASE-Dinero, JCachesim, RM, RSIM, SIMCA, SimFlex, SimOS, and SimpleScalar.
- 19. Conclusion The evaluation, based on the topics coverage criteria, shows that there is no single simulator which covers all topics. The best overall topics coverage is achieved with simulators M5 (69.57%) and Simics (64.13%), while most of other simulators achieve about 30.00% coverage. The evaluation, based on the simulation features criteria, shows that there are many simulators which meet a great number of these criteria. Simulators EDCOMP, HASE, ISE Design Suite, JHDL, M5, and Quartus II meet most of the criteria.

The paper presents the approach followed at the Faculty of Engineering of the University of Porto, to introduce design automation tools and structured design techniques in the rst course on digital system design of our Integrated Master in Electrical and Computer Engineering. Paper approach the use of Electronic Design Automation tools with a recongurable platform based on a Xilinx FPGA LABORATORY EXPERIMENTS In the rst laboratory assignment students build a basic digital circuit with gate-level logic devices The second block of laboratory experiments leads the students from the gate-level design of an adder/subtractor to the construction of an elementary microprocessor. It includes a sequence of four lab assignments, leading to the construction of a simple, albeit fully functional, 8-bit RISC-style microprocessor. The third and nal block of labs deals with the MIPS assembly programming FPGA board and development tools The sequence of laboratory assignments leading to the development of the microprocessor, makes use of a low cost development board with recongurable logic: the Spartan-3 Starter Kit . After designing the circuit with the ISE WebPACK Design Software from Xilinx, the students program the FPGA and validate the expected results.
