Most wireless headphones and speakers rely on some type of digital signal processing. Here's what you need to know about DSP—and why it's hard to avoid. I've been a contributing editor for PCMag since ...

�A fast floating-point DSP IC can use its built-in direct memory access (DMA) support to capture each sample from the ADC. The algorithm can completely process the sample and save the result in a ...

Part 1 shows how to build a software framework, choose between cache and DMA, and partition instructions and data for optimal performance. Part 3 explains how to optimize code placement and data ...
