(This year's digital signal processing market update highlights solutions and platforms that are now able to run extremely intense computational requirements in real time, as required by consumer applications (e.g., voice detection and acoustics optimizations). Increasingly, these platforms are evolving in large scale, targeting the ability to run artificial intelligence inference directly on-device.)
