Dual-core audio MCU has hardware acceleration for FFT and neural networks

Knowles has announced a dual-core audio processor chip for multi-microphone edge processing  – for example, for local spoken-word control of products. Called IA8201, it includes a 128bit four-way floating-point SIMD ‘DeltaMax’ core for beam-forming, barge-in, acoustic echo cancellation (AEC) and machine learning, for example, and a Tensilica HiFi3 core ‘HemiDelta’ with two-way floating-point SIMD for ...
