Introduction

The xcore.ai evaluation kit comprises an xcore.ai processor with a set of IO devices

and connectors arranged around it, as shown in in Figure 1. Except for the flash, all

components are optional, and are there to aid you in exploring the capabilities of the

xcore.ai processor.

A Quick-Start XM-014238-PC guide is available that has a few programs that you can run

that show how to use the tool-chain and the libraries.

1.1 The xcore.ai Cross-Over Processor Device

The xcore.ai evaluation kit is based on a two-tile xcore.ai device (XU316-1024-FB265),

shown in Figure 2. Each tile is user-programmable, providing eight logical cores with a

total of up to 1400 MIPS/MFLOPS compute, or 40 GMACC/s vector performance. A total

of 58 general–purpose digital I/Os, distributed from both tiles, have been brought out to

header pins, providing flexibility for connecting peripherals to the xcore.ai evaluation kit

board.
