2 Ken Davidson	Task Manager Life's Little Mysteries
6 Harv Weiner	New Product News
12 David Tweed	DSP-Based Canadian Timecode Receiver Part 1: Identifying DSP Techniques Many people get too caught up in the mathematical details of DSP. To prevent this, David takes a graphical approach. He introduces an app and its high-level design, identifying the necessary DSP techniques involved.
20 Dave Ryan Asher Hazanchuk	On- and Off-Hook Caller ID Using DSP Phone companies have already made on-hook caller ID popular. But, you can also quite easily gain this feature off-hook. After reviewing caller ID basics, Dave and Asher show us how to implement it using DSP. Download: CIDDSP.ASM
26 Chris Sakkas	PC Telephone Interface Chris shows you how to make a low-cost expansion card with a complete telephone interface. His software enables you to create applications for voice messaging, call processing, outbound calling, and home automation. Download: PCPHONE.ZIP
30 Art Sobel	Embedding the ARM7500 Part 2: Programming an Embedded Computer Building on last month's introduction of the ARM7500, Art moves from chip architecture and development boards to firmware. He wants to make sure we have the instruction set that makes it zip! Download: 75DEMON.ZIP ARMlist.zip
Embedded PC 40 Harv Weiner	Nouveau PC
Embedded PC 45 Raz Dan	An In-Depth Look at FTL Since FTL-based drivers are becoming more common, you need to know more than the basics. After discussing FTL technology and algorithms, Raz showns us how TrueFFS interfaces to many storage devices.
Embedded PC 53 Rick Lehrbaum	PC/104 Quarter To ROM or NOT to ROM, That is the Question We all take for granted the three minutes of boot-up time for desktop computers. But, we'd never tolerate such performance in a task-specific system. Rick looks at ways to gain instant response from an embedded PC/104 computer.
Embedded PC 60 Fred Eady	Applied PCs Right on Cue, National Presents Slimline 'x86 Fred measures and stores voltages at specified times using National's NS486SXF. He showns how to get the ADC data into the '486 for processing, store the data to EEPROM, and use Vetra's Reverse Pipe for keyboard access.

66 Hugh Anglin	MicroSeries Machine Vision, Part 1: Industrial Inspection Ever hear of Inspector Gadget? He'd love to learn how Hugh blends a computer, camera, sensors, and RTOS software to make a small-scale vision inspection system.
74 Jeff Bachiochi	From the Bench It Can't Be a Robot, Part 1: There are No Arms and Legs! Robotics has been riddled with too many preconceptions. Over the next few columns, Jeff intends to look at some of the areas that make robots tick. This month, he concentrates on getting the motors going smoothly.
78 Tom Cantrell	Silicon Update High-Velocity DSP Tom's view: bit by bit, we've crept ahead through boosting clock rate and memory, but to make major leaps, we need a paradigm shift. Enter DSPs. They offer the optimal combination of data and signal processing.
96 Steve Ciarcia	HTML Priority Interrupt A Winning Proposition
