Do-While Jones

Rediscovering Analog Computers

In an increasingly digital age, it's easy to forget that the analog computer fills a special niche. Here Do-While shows us how an analog computer creates the best simulation for testing a cruise-control algorithm.


David Prutchi

Parallel Processing with Transputers

Uniprocessor technology is at a limit. Greater speeds require new technology. Instead of paying the increased costs, David advocates parallel processing. Find out how to build your own Transputer.


Michael R. Smith

Developing a Virtual Hardware Device

Mike finds out what it takes to simulate virtual devices on the buses of MC68332 CISC and AM29200 RISC microcontroller evaluation boards. His concern: how the simulators deal with exception handling of bus errors.


Ed Lansinger

Developing an Engine Control System

Part 3: Completing the System

Ed finishes his series on the engine control system by looking at the last critical parts: the crankshaft position detector, automatic shutdown, and power supply. He ends with how to tune the complete system.

Journey to the Protected Land: Real Interrupts in Virtual-86 Mode

For an 'x86 processor running in Virtual-86 mode, processing an external interrupt is no small feat. If your DOS comm program has ever dropped characters while running under Windows or OS/2, you'll soon understand why.

ADSP4ME: Audio Processor Chips for the Masses

In INK 63, Tom showed how the latest digital video chips take much of the mystery, cost, and headaches out of tough designs. Here, he takes a look at the AD1847 and ADSP-2181 that handle audio with the same panache.
