2 xCORE Multicore Microcontroller Device
The xcore.ai Multichannel Audio board (XK-AUDIO-316-MC-AB) is based on a two-tile
xcore.ai device (XU316-1024-TQ128-C24). Each tile is user-programmable, providing eight
logical cores with a total of up to 1200 MIPS compute per tile. The device has an integrated
high speed USB interface which allows connection to a USB host. The device has a large
amount of digital IO which are used for interfacing to the on board components, spare
IOs are wired to expansion headers.

3 Boot
The xcore.ai device boots from an on-board QSPI FLASH memory. The device on the
board is 32Mbit in capacity to allow for experimentation but in target applications it is
expected a 16Mbit or smaller device would be used to reduce cost.
The FLASH is connected as shown in Figure 3:
