Here are two old pictures from when I
wore glasses and shaved!
For a recent picture look below or at my vita.
I am now Professor Emeritus of
Mathematics, Electrical and Computer Engineering, and Computer Science at The University of Texas at Dallas (UTD).
For information on what I've been up to, you may want to take a look at my vita.
During the 2003-2004 Academic Year I
was on Special Faculty Development Assignment (Sabbatical).
I did research on Digital Signal Processing software and hardware.
In addition, I wrote the below mentioned book on MIPS assembler.
The source code for the first
edition of my book "A Programmer's Guide to Assembler"
published by McGraw-Hill Custom Publishing, 2005 (ISBN = 0-07-353923-6)
is available as a "zipped" file by clicking here.
For a complete ERRATA, click here .
The third edition, published in 2010, is ISBN 0-07340887-5 and includes corrections of all those errors.
The code for programs in the first twelve chapters can be downloaded as above.
The code for programs in Chapter Thirteen may be obtained by clicking on the names of the programs here:
page 149 c code , Hello
World on page 150 , Factorial on page 154 ,
Fibonanacci on page 155
There is a new (September 4, 2011) version (9.1.0) of PCSPIM called QtSpim available through https://sourceforge.net/projects/spimsimulator.
Older versions of PCSPIM are still available through James R. Larus.
Another example of recursion beyond what is in the text is available with code for the classical QuickSort.s program.
I've worked in a wide variety of
research areas. For more detailed information, you may want to glance at my list of publications.
I have directed Ph.D. dissertations in Mathematics, Computer Science, and Electrical Engineering.
Most recently I have written the above mentioned book titled "A Programmer's Guide to Assembler"
published by McGraw-Hill Custom Publishing, 2005 (ISBN 0-07-353923-6) and 2010 (ISBN 0-07340887-5).
Former work includes material for a Web-Based Course
in Symbolic Logic being supported by the University of
Texas System as part of the Multimedia Educational
Information Delivery initiative.
A draft preliminary version of the "Sophocles User's Guide" is available here.
Recently, my main interest was in the development of Digital Signal Processing courses for Computer Science Students.
In addition, I hoped to develop an advanced assembly language course based on a DSP chip. Refer to DSP for CS Students.
At present I am working on a workbook for ARM Assembler Programming.
Since 1953, when I first
taught Freshman Calculus, teaching has been an extremely important and
satisfying part of my career.
Since then I have taught almost every Mathematics course, almost every Computer Science course, and even some Electrical and Computer Engineering courses.
That diversity has kept me interested in continuing to teach.
I divided my teaching effort between individual instruction (such as working with Ph.D. students) and teaching organized courses.
I encourage students to come talk with me in my office.
I will not, however, be taking on any more Ph.D. students nor do I have any Research Assistantships available.
Please avoid the telephone since I usually do not get such messages.
I will often be in my office in ECSN4.626
but interested students should e-mail me
and make an appointment so as to be sure
I will be there at any particular time.
UTD has available quite a lot
of software for students.
For example, the Adobe Acrobat reader and other programs needed for many courses may be downloaded from
from a campus computer.
