There are a growing number of software packages that offer the features required by both DSP applications and microcontroller applications. With a broader set of requirements, software solutions are more rare. They require: development tools, DSP libraries, optimization for DSP processing, fast interrupt handling, multi-threading, and a tiny footprint. </p> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>"dsPIC® DSCs | Microchip Technology". www.microchip.com.
