The Cortex-M7 doubles the DSP capabilities of its Cortex-M4 predecessor. Once again DSP Concepts provided the DSP CMSIS library to power this DSP capabilities. And incorporating this already into our Audio Weaver® tool, we can help bring about audio products based on the Cortex-M7 to market faster. The same audio designs made in Audio Weaver® can be automaticallly ported to the Cortex-M7 using much lower MIPs and without having to re-code or additional optimization.

The DSP capabilities of ARM's Cortex-M4 is just being discovered. Using the CMSIS library provided by DSP Concepts, developers are able to create fabulous technologies that helps soldiers injured in war. This blog of a bionic robot hand shows how the use of CMSIS DSP library allows innovaters to take and create technologies that were thought capable only in major industry sections by major companies. But, the democratization of specialized DSP codes has made this possible for the maker community. The now lowered barrier to entry will spur on innovation in different areas to make this...

Here is a blog we wrote for ARM. "Make versus Buy?". This is a question every company need to think through. This decision takes wisdom from those in decision making positions. Only from a vantage point of seeing the full landscape can this decision be made. Often time in a big organization, the engineers are nothing more than a cog in a big machinery, and our clients whose engineers are empowered to look outside to purchase resources are the ones that exhibit innovative...

When you think of excellence, what picture or person comes into mind? For me, it usually means a specialized skill set. If I want the best doctor to deal with my heart problem, I wouldn’t go to a generalist, I’d find a cardiologist who even further specialized in a particular heart disease or problem and who has lots of lots of experience handling that problem. I would never consider a restaurant that served every type of food first rate. Usually we know that if you want the best sushi, go to a restaurant that specialized in making fresh sushi. An all-around triathlon athlete, though...

DSP Concepts has been a technology partner for many clients in the past 12 years. Our single focus is audio DSP to help our customers deliver the best audio products. The common thread for our customers is their foremost concern for high quality audio. In this blog I will talk specifically about a subtle problem that one of our customers encountered with using a free Linux open source Sample Rate Converter.

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.
