MNEME: A memory hierarchy simulator for an engineering computer architecture course

Self Cite

This article presents an educational tool for the teaching of Grafcet language for programmable logic controllers (PLC) and its application in the subject ''Digital Devices for Industrial Automation'' in a Industrial Electronics Engineering course. Apart from a simulator with its own editor, the tool includes a syntax controller with the purpose of maintaining Grafcet standard. In this way, the tool makes the validation of the implemented scheme easier. ß

“…Beside the computer simulators, there are also simulators of a particular part of computer systems. For example, Moreno et al present a simulator of a computer‐memory hierarchy. This multi‐platform simulation tool, developed in Java, enables a huge set of concepts and parameters and has been validated and improved by students.…”

“…To overcome this, such a program can be run on a dedicated simulator. Various simulators are often used in practice for educational purposes . Several SIC/XE simulators and assemblers were already designed , but to our knowledge none of them provides a sophisticated executing and debugging graphical user interface (GUI).…”

A modern computer system provides its support via system software that consists of applications such as an assembler, a linker, a loader and virtual machines. It is of prime importance to give students that are learning system‐software concepts a solid base of knowledge without any unnecessary details. To make the subject easy to understand we designed a simulator for a hypothetical computer that is already used in several courses on system software. In the paper, we describe the simulator's behavior as well as its design and implementation. Additionally, we present three case studies of using a simulator in teaching and describe our experience of its use in a course on system software. From the experience of using the simulator in a pedagogical process we conclude that it decreases the time invested by the students to comprehend the topic, and at the same time it enables in depth understanding. © 2013 Wiley Periodicals, Inc.

Learning memory management with C‐Sim: A C‐based visual tool

et al. 2019

Nowadays, Computer Science (CS) students must cope with continuous challenges related to programming skill acquisition. In some occasions, they have to deal with the internals of memory management (pointers, pointer arithmetic, and heap management) facing a vision of programming from the low abstraction level offered by C. Even using C++ and references, not all scenarios where objects or collections of objects need to be managed can be covered. Based on the difficulties identified when dealing with such low-level abstractions, the C-Sim application, aimed at learning these concepts in an easy way, has been developed. To support the tool, the C programming language was selected. It allows showing concepts, remaining as close as possible both to the hardware and the operating system. To validate C-Sim, pre and posttests were filled in by a group of 60 first-year CS students, who employed the tool to learn about memory management. Grades of students using C-Sim were also obtained and compared with those that did not use the tool the former academicyear. As main outcomes, 82.26% of students indicated that they had improved programming and memory management knowledge, and 83.64% pointed out that the use of this type of tools improves the understanding and quality of the practice lessons. Furthermore, the marks of students have significantly increased. Finally, C-Sim was designed from the ground up as a learning aid and can be useful for lecturers, who can complement their lessons using interactive demonstrations. Students can also employ it to experiment and learn autonomously.
