Digital Systems: From Logic Gates to Processors

<b><font size=4 color=#B22222><b>Click on "v More" to read the purpose of this module</b></font> </b>

<br/><br/>This module is an introduction to Digital Systems. Here you will find:<ol><li>A set of videos_L covering issue 1 and the corresponding exercises, </li><li>Two videos_P introducing the processor that we will design along the course, and</li><li>Some video-based explanations; a wiki and some FAQs about how VerilUOC_Desktop tool functions.<br/> You will have to use VerilUOC_Desktop in the next module</li></ol> Read the "Lesson Index" in the "Index and PDF files" section and the "README" in the VerilUOC_Desktop section for more information.

<b><font size=4 color=#B22222><b>Click on "v More" to read the purpose of this module</b></font> </b><br/><br/>From this week you will need to use VerilUOC_Desktop to do some of the exercises in the quizzes. VerilUOC_Desktop is a software package based on Logisim, enhanced with a number of modules to enable:<ul><li>Enter Boolean equations (BoolMin),</li><li>Enter digital circuits and check them according the problem statement (VerilCirc), and</li><li>Enter chronograms (time-charts) and check that they are correct (VerilChart).</li></ul>This section contains two videos explaining how these three tools work. By now you only need to use VerilCirc and BoolMin, so if you are pushed for time, you might postpone VerilChart for later. Obviously, it is impossible to cover in these two videos all eventualities you can find while working with VerilUOC_Desktop tools. In case of doubt, look at the VerilUOC_Desktop wiki, look at the FAQs or post your problems in the forums. There are specific forums for VerilCirc, BoolMin and VerilChart.

<br/><br/>We continue the study of combinational circuits. While in the previous module we were working on the classical design techniques of combinational circuits, this one is focused on other issues such as a brief introduction to computer aided design tools (CAD tools), or the direct synthesis of combinational circuits from its algorithmic description.<br/> Read the "Lesson index" for more information. <br><br/><b>To solve the exercises in this module VerilUOC_Desktop is needed. </b>Remember that the "VerilUOC_Desktop" section in module 2 contains all the information you need about this tool.

<b><font size=4 color=#B22222><b>Click on "v More" to read the purpose of this module</b></font> </b><br/><br/>Arithmetic circuits are an essential part of many digital circuits and thus deserve a particular treatment. <ul><li> The first part of this module presents some implementations of the basic arithmetic operations. Only operations with naturals (non-negative integers) are considered. </li><li>The second part of this module introduces the basics of VHDL with the goal of providing enough knowledge to understand its usage throughout this course and start developing basic hardware models.</li></ul>
