Mixed-Signal
AVR Simulator
by Engin
Ipek & Bruce Land
Engin and Bruce have
designed a mixed-signal AVR simulator that you can
use to analyze the analog, digital, and program
behavior of small systems built around AT90S8515
microcontrollers. The simulator is a great tool
to have in the classroom, but, as you’ll soon see,
it’s also perfect for your workbench, particularly
because you can modify the source code to handle
multiple processors. p.14
Keywords:
Simulator, AVR, AT90S8515,
analog, digital, Java, parser

Timing
(Analysis) is Everything
A How-To Guide for Timing Analysis
by
Philip Nowe
Philip’s main issue with young engineers
is that many of them have been taught excellent
circuit design techniques but haven’t been schooled
in the importance of timing analysis. What is timing
analysis? Why is timing analysis important? How
do you perform timing analysis? Whatever your level
of expertise, you’re sure to find Philip’s answers
informative. p. 28

Pure
Digital Audio
Build An All-Digital Amplifier
by
Yoon Cho, Joe Huntley, Greg Nuttall, Bryan Olson,
& Derek Richardson, edited by David Tweed
What do you get when you lock a group
of engineers, a PIC16F877, and various audio parts
in the same electronics lab? Just what you’d expect—an
intelligent design that will enhance any home entertainment
system without breaking the bank. Follow this step-by-step
article, and you’ll soon have a powerful, all-digital
audio amplifier for your home entertainment system.

Hierarchical
Menus in Embedded Systems
by
Aubrey Kagan
What is the most efficient method for implementing
menu structures in embedded systems? Aubrey had
been mulling over this question for several months
until he recently worked out a way to implement
a hierarchical menu system that allows you to reuse
software for displaying and changing parameters
to save ROM space and achieve maximum flexibility.

High-Temperature
Superconductor Overview
by
Danny Graves
The expensive cooling processes needed to achieve
the superconducting state can make using superconductors
impractical. High-temperature superconductors, on
the other hand, don’t need to be cooled as low,
and are therefore less expensive to use. Danny’s
review covers the basics to get you started experimenting
with high-temperature superconductors. p. 56
Keywords:
Superconductor, high temperature, HTS, resistance,
liquid nitrogen, YBCO, Meissner effect, applications

Programming the 386 in 32-Bit Protected Mode
by
Jim Turley
Remember when the 386 was the hottest chip on the
market? Today, there are dozens of other 32-bit
CPUs, and the 386 is no longer the superlative processor.
But wait, there’s a lot you might not know about
the 386. In this article, Jim explains how entering
Protected mode will open your eyes to the 386’s
applicability. p. 60

by Fred
Eady
Think
of Fred as your own personal litmus test for
all of the new embedded technology thrown
your way. This month, he brings the LPRS easy-Radio
to the Florida room and puts it to the test.
Read on to find out if his results impress
you enough to try your hand at building an
easy-Radio/CH2124 modem station. p. 64

OOPic Eases Programming Headaches
by
Jeff Bachiochi
Does programming give you a headache? If so, Jeff
recommends OOPic, which allows you to combine predefined
objects (e.g., keypads and LCDs) in a virtual circuit,
and then compile and download the code in a special
processor. It’s that simple. p. 70

SILICON
UPDATE
Go Sell the Spartans
by Tom Cantrell
What does the future hold for the modern FPGA? The
answer isn't cut and dry. FGPAs are massively successful,
but as time passes on, they are becoming increasingly
complex and remaining pricey. This month, Tom looks
at the direction of the FPGA industry. p. 76
