 | Electronics: Digital Multitasking (June 2008)
Appliance technology has evolved significantly over the years, and two trends are merging to fuel the next round of appliance evolution — digital motor control and digital sensor processing. Digital Signal Controllers (DSCs) are at the confluence of these trends, and they enable digital sensor processing, digital motor control and power factor correction to be implemented on a single chip.

 | Motors: Extending Efficiency (Oct. 2007)
Advanced motor-control techniques are a practical
necessity because they enable more efficient and quieter appliances. In the
past, these advanced control techniques were only available as proprietary
solutions, and hence were limited in scope to a few high-end appliances. Given
the drive toward efficient appliances running on “green” power, which is
mandated by regulations and customer preferences, these motor-control
algorithms are now being sought by designers of all classes of appliances.
Thanks to the new generation of digital-signal-controllers (DSCs), the
cost-effective implementation of advanced motor-control algorithms has become a
reality.
