The hardware platform uses the XS1-L16 multicore microcontroller. A member of the XMOS xCORE-General Purpose™ family, this device has 16 logical cores delivering 1000MIPS of deterministic and responsive processing power. Exploiting the flexible programmability of the xCORE™ architecture, the platform supports USB audio streaming of up to 20 channels at 192kHz, and includes 18in/8out audio mixing functionality. The guaranteed Hardware-Response™ times of xCORE technology always ensure low latency (round trip as low as 3ms), bit perfect audio streaming to and from the USB host. Delivered as source code, the reference software provides a fully featured production ready solution, including support for: Full- and HighSpeed USB operation, USB Audio Class 2.0 & 1.0, MIDI, HID and DFU classes. The XMOS xTIMEcomposer™ Studio development suite and tools then allow for quick and easy software development and customization to add customer specific, product differentiating features.
