XVF3610 Processor for Audio Capture

XMOS' VocalFusion XVF3610 voice processor uses a microphone array to capture and process high-quality audio. Audio streams are suitable for automatic speech recognition (ASR) and other voice communication applications. The VocalFusion XVF3610 voice processor provides four general purpose output pins that can be configured as simple digital I/O pins, pulse width modulated (PWM) outputs, and rate-adjustable LED flashers, and four general purpose input pins. These can be used as simple logic inputs or event capture (edge detection) and an SPI primary interface to control and query an SPI secondary device, such as an ADC, DAC, or external keyword detection device.
