DSP-Based Canadian Timecode Receiver
Part 1: Identifying DSP TechniquesMany 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.
On- and Off-Hook Caller ID Using DSPPhone 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.
PC Telephone InterfaceChris 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.
Embedding the ARM7500
Part 2: Programming an Embedded ComputerBuilding 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!
An In-Depth Look at FTLSince 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.
To ROM or NOT to ROM, That is the QuestionWe 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.
Right on Cue, National Presents Slimline 'x86Fred 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.
Machine Vision, Part 1: Industrial InspectionEver 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.
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.
High-Velocity DSPTom'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.
