  • far-field voice capture
  • sound analysis
  • actuator control

 

XMOS array microphone solutions use the high performance multichannel capabilities of xCORE devices to aggregate PCM streams from large numbers of MEMS microphones to USB and TDM interfaces. The flexibility of xCORE means that independent streams of voice samples from arrays of PDM or I2S microphones can be easily backhauled to application processors, DSPs and PCs, in a single device.

Why XMOS?

  • Interfaces to large arrays of MEMS microphones - PDM or I2S
  • High quality format conversion, decimation and sample rate conversion
  • Independent streams of voice samples from microphone array
  • Standard backhaul - USB or TDM
  • Additional GPIO for local HMI appliance controls
  • Cost reduction - microphone and backhaul interfaces in a single device
  • Customer adds own DSP to create differentiated product

ARRAY MICROPHONE EXAMPLE

 

ARRAY MICROPHONE DEVELOPMENT BOARDS

The xCORE Array Microphone kit offers a scalable and flexible hardware and software solution for high performance, low cost multi-channel USB microphone aggregators and array microphones. Built around the xCORE-200 series of multicore microcontrollers, it provides direct interfacing to seven PDM (Pulse Density Modulation) microphones and a high speed USB2.0 device.

The microphone interface library is highly configurable and enables designers to customize the functionality of the system to meet their specific requirements.
