The best of both worlds

DSP and microcontroller functionality on a single chip. By Richard Fischer and Steve Bowling.

A growing number of embedded applications require signal processing functionality in addition to conventional control functions. More than half the current users of 8 and 16bit microcontrollers predict they will require some digital signal processing (dsp) functions for their future embedded designs.

Many design trends are driving this market: an increased number of embedded applications requiring interconnectivity via internet and other communication vehicles; the movement to more complex motor control techniques driven by variable speed drives; energy efficiency demands; reduction of generated noise and the drive to reduce costs and size of motors; precise real time response in automotive systems; secure access in connected systems; and the need for additional performance in segments of the 8bit microcontroller market.

Richard Fischer is principal applications engineer, Steve Bowling is a senior applications engineer. Both are with Microchip Technology
