Real-time last minute tuning capabilities essential to making a good audio product

September 17, 2002
From the feedback of some Asian ODMs, I learned that ARM’s Cortex-M4 was not favored in Asia for audio applications even though we see a slow trend from our customers here in the US and Europe to replace traditional low cost DSPs with ARM’s Cortex-M4 for its easy USB connectivity capabilities.  The Chinese market has not yet embraced this because of the very low cost so called “SOC” in China that come as low as $0.20/piece.  The “SOC” are in fact non-programmable ASICs that come with the mp3 decoder and one or two built-in audio functions.
