24-bit audio DSP core

NXP conducts a successful licensing program for this embedded DSP core for ultra low power applications.

Overview

CoolFlux DSP is a 24-bit audio DSP core developed with years of experience in Ultra Low Power Design at NXP's ultra low power design group in Leuven. Later on NXP completed new cores in the CoolFlux DSP family optimized for Baseband Signal Processing such as for Software Defined Radio: the CoolFlux BSP and the 32-bit CoolFlux BSP32. Also smaller 16-bit cores have been added: CoolFlux DSP16L and CoolFlux DSP16 for speech and intelligent sensor signal processing.

The CoolFlux DSP line is embedded in chips for many Smartphones, Hearing Instruments, Headphones and Headsets, MP3 players, Mobile Multimedia, Blue Ray players, Wireless Audio, Car, Digital TV … any embedded audio subsystem is candidate.

The CoolFlux BSP line is embedded in chips for ultra-low power software defined radio basebands chips. It was also demonstrated DAB reception.

The CoolFlux DSP16(L) line is used for ultra-low power intelligent sensor signal processing and speech processing.

Application firmware is also available upon request.
