Ultra low power C-programmable DSP core

NXP conducts a successful licensing program for this embedded DSP core for ultra low power applications. Based on many years of experience in the design of ultra low power electronics, the core was developed for portable audio applications, including audio encoding and decoding, sound enhancement algorithms, and noise suppression. Products powered by CoolFlux DSP include hearing devices, mobile phones, portable audio players and portable media players.

NXP distributes the CoolFlux DSP core through its corporate Innovation & Technology (I&T) division with license support of NXP's Intellectual Property & Licensing Department (IP&L).
