Analog movements go digital with DSP: DSP for motion control. (Digital Signal Processors) (EDN-Technology Update) (Technical)

From: EDN | Date: June 18, 1992| Author: Mosley, J.D. | Copyright information

The cost of digital signal processor (DSP) integrated circuits (ICs) continues to come down, and one consequence is that design engineers are starting to use DSPs for applications that involve motion control. For example, DSP-based motor-control circuits are being incorporated into miniaturized hard-disk drives, and DSP chips are being used in automotive and robotic controls. DSP chips are well-suited to motion control. They have high-speed hardware multipliers and on-chip memories which faci...

Analog movements go digital with DSP: DSP for motion control. (Digital Signal Processors) (EDN-Technology Update) (Technical)
EDN ; Motion control has traditionally been an analog function. However, 16-bit DSP chips--selling for as little as $3 in OEM quantities--are demonstrating that with enough speed and power you can use binary data to represent continuous movements while reducing the size and cost of your control circuit
EDN Special Report: 32-bit floating-point DSP processors. (digital signal processing) (Cover Story)
EDN ; Processing power is here for engineers who need it. Today's 32-bit, floating-point DSP processors offer 25 to 50 million floating-point operations per second-power readily available for heavyweight, math-intensive applications. To use digital signal processing (DSP), engineers familiar with only
