The xcore.ai evaluation kit allows testing in multiple application scenarios and provides a good general software development board for simple tests and demos.
- the xcore.ai crossover processor
- 4 general purpose LEDs
- 2 general purpose push-button switches
- a PDM microphone connector
- audio codec with line-in and line-out jack
- QSPI flash memory
- LPDDR1 external memory
- 58 GPIO connections from tile 0 and 1
- micro USB for power and host connection
- MIPI connector for a MIPI camera
- xSYS2 connector for debug adapter and a reset switch with LED to indicate running.
The voice reference design evaluation kit can be used as a Raspberry Pi HAT for integration with example AVS client or used standalone as a USB accessory to a host system.
- XU316-1024-QF60A-C24 xcore.ai processor
- Raspberry Pi HAT connector
- 2 x Infineon IM69D130 MEMS mics
- 71mm inter-mic spacing
- Microphone mute switch
- Speaker output (Line level)
- USB / I2S host interface support
The XK-VOICE-SQ66 4 microphone evaluation kit allows evaluation of the XVF3800 application. The design includes:
- an XVF3800-QF60B-C processor
- QSPI flash memory
- a DAC for audio output
- a USB interface and 6 PDM microphones.
These microphones can be configured as either a 100 mm linear or a 66mm square 4 mic array to match target form factors.
- An extension connector can be fitted that allows a user to connect their own custom microphone array to the device.
- Firmware loading and debug access is provided via an XMOS standard XSYS2 connector which supports the XTAG4 debug adapter.
- The board can operate stand alone and has a 40 pin HAT complaint connector and form factor which allows it to be mounted on top of a Raspberry Pi host.
The xcore.ai multichannel audio platform provides a scalable and
flexible hardware and software solution for a wide range of consumer
and professional audio products.
The multichannel audio platform is based on an xcore.ai multicore
controller; the XU316-1024-TQ128-C24, and includes a high-speed
USB 2.0 PHY, flexible GPIO and 16 logical cores that deliver up to 2400
MIPS of deterministic processing power.
The Explorer Kit features the XE216-512-TQ128 device with sixteen logical cores delivering up to 2000MIPS deterministically. The high-speed USB interface, 10/100/100 Mbps Ethernet interface and 53 high-performance GPIO make it ideal for a wide range of applications, including networking and digital audio. The board also carries a 3D accelerometer, 3-axis gyroscope and six servo interfaces for rapid prototyping of motor and motion control projects.
XVF3500 dev kits are available to help you evaluate the XVF3500 and prototype your voice enabled products. There’s a dev kit that’s qualified for Amazon Alexa Voice Service and a dev-kit for other voice control and voice assistant implementations.
XTAG 4 DEBUG ADAPTER
Used with our tools for xcore®.ai boards supporting the XSYS2 connector.
It connects via a 20-pin 0.05 IDC XSYS2 connector, which incorporates JTAG, Reset, a high speed xLink, and advanced debug signals. Whether executing and updating flash memory, or performing advanced debug, the xtag is essential for xcore.ai development.
For use of the XTAGv4 with our tools, see XTC Tools Guide
XTAG 3 DEBUG ADAPTER
Used with our tools for xcore-200 boards supporting the XSYS connector.
It connects via a 20-pin 0.1 IDC XSYS connector, which incorporates JTAG, Reset, a high speed xLink, and advanced debug signals. Whether executing and updating flash memory, or performing advanced debug, the xtag is essential for xcore®-200 development.
