IA8201
The IA8201 includes a high compute 128-bit core (DMX) with AiSonic proprietary instruction set and a Tensilica HiFi3 core (HMD), both with AiSonic audio enhancements. The DMX is a 4-way floating-point SIMD processor targeted towards efficient performance computing (e.g. beam-forming, barge-in, AEC), while the HMD is targeted towards efficient, low-power, wake-on-voice applications with a two-way floating-point SIMD processor. Both cores contain dedicated accelerators for FFT, peak finding and DNNs.
A rich set of audio, and general purpose high speed interfaces enable flexible interfacing with digital microphones, other sensors, and a host for further processing. 1MB of user RAM enables storage of multiple algorithms and voice keywords.
