What Makes Digital Signal Processors So Fast?
Jatin Chowdhury

There has been significant changes in computer hardware over the past two decades, however most publicly available advice on performance engineering and optimization for DSP software is unchanged from the late '90's or early 2000's.

This talk will discuss some of the features available in modern CPUs and DSPs including SIMD vectorization, execution pipelines, and hardware caching, as well as advice for how to optimize DSP code with those features in mind.
