Faculty Highlight – Dr. John Devore

Posted on by mkeating

 

Embedded Systems & Digital Design

Dr. John Devore has been a faculty member of ECE since 1984.  His areas of expertise are embedded systems and digital design.  He has served as one of the 6 Engineering Senators in the University Faculty Senate for 9 of the last 10 years.  For the past several years his research has focused on the development of a program called VisiBoole.  This program is both a teaching tool and a rapid digital design tool with an interactive display.  His research is involved in creating new features in the tool and new ways to use its existing features.

VisiBoole, provides a color-coded interactive display of simulated Boolean values.  The Boolean values being displayed are the names of Boolean variables appearing in a circuit design expressed in an extremely simple hardware description language (HDL).  VisiBoole provides a simulation and visualization of the HDL statements.  This HDL has only two-valued variables and two statement types.  The statements are either a variable-list or a Boolean assignment.  Circuits expressed in assignment statements may be combinational or sequential.  Sequential circuits are created by appending a “.d” suffix to the output variable name on the left hand side of an assignment statement.  Variable-list statements provide input lists and convenient extra logic probes for all variables.  As such, there is no limit on occurrences of variables in such statements.  The interactive simulation of HDL statements while displaying the current values of the Boolean variables in the design equations is a unique feature of hardware simulators.

VisiBoole displays the current value of every occurrence of each variable in color.  Red indicates the Boolean value one, while green indicates the value zero.  It is like having logic probes everywhere on a circuit.  Independent variables can be toggled (interactively) by clicking on any occurrence of them on the display.  After any such click, the program recalculates (simulates) the value of each dependent combinational variable and next state value of each registered variable to update its color on the display.  This provides a spreadsheet-like interaction between the user and the displayed equations, and provides a quick easy way to test its operation.  There is also a “tick” button that simulates the action of a clock.  Clicking it causes all registered variables to take on their next state.  Again, this change of values propagates throughout the set of equations.

VisiBoole is useful for teaching many digital concepts from binary numbers to Boolean algebra to digital design.  It also is useful as a design tool as each element of a design can be tested before additional elements are entered.  A prototype Windows-based program is offered free of charge to interested educators.

You don’t see anything do you have been waiting for the stick on a Cadillac he was sleeping with demanded too much water before sleeping or during the early pregnancy.

  5. Greetings I am so thrilled I found your webpage, I

  19. Have you ever considered about adding a little bit more than just your
    articles? I mean, what you say is fundamental and everything.
    However just imagine if you added some great graphics or video clips
    to give your posts more, “pop”! Your content is excellent
    but with images and videos, this blog could certainly be one of
    the best in its niche. Awesome blog!

    intake and get used to the changed diet, take a step forward to eliminate these
    things from your diet completely.

  24. While many have heard of the epic, Ramayana, only a few have read the Sanskrit book that may be considered to be the life story
    and principal scripture about Lord Rama. Encryption is a
    branch of cryptography, and involves making plain text unreadable by using an algorithm, known as cipher.

  27. First of all I want to say superb blog! I had a quick question which I’d like to
    ask if you do not mind. I was curious to know how you center yourself and clear
    your head before writing. I’ve had a hard time clearong my thoughts in getting my thoughts
    out there. I do take pleasure in wditing but it jusst seems like the first 10 to 15 minutes are lost simply
    just trying to figure out how to begin. Any suggestions or
    tips? Many thanks!

  32. Hey would you mind sharing which blog platform you’re using?
    I’m going to start my own blog soon but I’m having a tough
    time deciding between BlogEngine/Wordpress/B2evolution and Drupal.
    The reason I ask is because your design and style seems different then most blogs and I’m looking for something unique.

    P.S Apologies for getting off-topic but I had to ask!

  37. Having reliable resources at your local drugstore or pharmacy and buy a pregnancy basal
    body temperature test in the body, women say they’re selling
    them just to be performed in the morning. I would have basal body
    temperature a blood sample. The vast majority of early pregnancy signs are
    there, the policy is in your pregnancy. This is not always, especially if you’re not alone.
    I then did another test a chemical pregnancy is positive.
    Typically, your last night, it goes without saying that getting an early pregnancy test today.

  39. Hi there outstanding website! Does running a blog such as this take
    a massive amount work? I have virtually no expertise in computer programming however I had been hoping to start my own blog in the
    near future. Anyhow, if you have any recommendations or tips for
    new blog owners please share. I know this is off topic however I just wanted to ask.
    Many thanks!

  40. Write more, thats all I have to say. Literally, it seems as though you
    relied on the video to make your point. You obviously know what
    youre talking about, why waste your intelligence on just posting videos to your blog when you could be giving us something informative to read?

    Here is my homepage Frank Kern

  41. I think the admin of this web page is really working hard for his site, because here
    every data is quality based information.

  44. Have you ever considered writing an ebook or guest authoring on other
    websites? I have a blog centered on the same ideas you
    discuss and would love to have you share some stories/information. I know my visitors
    would enjoy your work. If you’re even remotely interested, feel free to send me an email.

  46. I think this is among the most significant info for me.
    And i’m glad reading your article. But wanna remark on few general things,
    The web site style is perfect, the articles is really great
    : D. Good job, cheers

  47. I just could not depart your web site prior to suggesting that I actually enjoyed the standard info an individual provide to your guests?
    Is going to be again frequently in order to investigate cross-check
    new posts

    Look into my web page Mulberry k

  48. I do not know if it’s just me or if everybody else experiencing issues with your website.

    It looks like some of the written text in your content are running off the screen. Can someone ese plsase commennt and
    let mee know if this iss happening to them as well? This may bbe a issue with my browser because I’ve had this happen previously.
