Yet Another Simple Processor (YASP) for Introductory Courses on Computer Architecture

Subjects that include short introductions to computer architecture are usually taught in the first year of electronic engineering and computer science degrees. To enable students to acquire practical skills in this topic, simple computers can be used. These computers are usually microcontrollers or education-specific machines. In this paper, we present a machine based on a simple processor that also has some of the characteristics of microcontrollers, such as integrated input/output ports. In addition, this machine is accompanied with a tool suite intended for educational purposes that includes several simulators, assemblers, and debuggers that have been gradually introduced since the academic year 1999-2000. Results show that students are satisfied with the integrated development environment and with the machine as an example of how actual computers work.
