This document describes a virtual laboratory for computer organization and architecture. It lists the principal investigator and developers involved. The objectives of the virtual labs are to encourage experimentation through curiosity and provide a learning management system with tools for learning. The introduction explains that the lab exposes students to key aspects of digital logic and computer organization through FPGA-based prototyping in a virtual environment. It is built using free and open-source software to accurately acquire data from instruments in real-time. The architecture involves a web browser, TCP/IP, and the virtual lab server. Procedures, the simulator, and examples of experiments like ripple carry adders and ALUs are described. Benefits include reduced time and work, user

3. OBJECTIVES OF THE
VIRTUAL LABS
Web-based learning plays a vital role in the modern education system,
where different technologies are being emerged to enhance this E-
learning process.
Objectives of the Virtual Labs:-
 To enthuse students to conduct experiments by the arousing their
curiosity. This would help them in learning basic and advanced
concepts through remote experimentation.
 To provide a Learning Management System around the Virtual
Labs where the students can avail the various tools for learning,
including additional web-resources, animated demonstrations and
self evaluation.

4. INTRODUCTION
 The Objective is to Expose the students to the various key
aspects of Digital Logic and Computer Organization by enabling
them to perform FPGA based prototyping of experiments with
support of a virtual environment.
 Computer Organization and Architecture is a core course in most
of the Undergraduate Curricula of the entire Electrical Sciences
Discipline(Computer Science / Engg., Electronics, Electrical) etc.
 This virtual laboratory is based upon FOSS
(Free and open-source software ).
 With this, we can acquire data accurately from instruments in
time with reality.
 A virtual laboratory is build to achieve an integrated
environment for measurement and instrumentation.
 A virtual lab is designed to enhance the efficiency of the
learners.
