Hardkernel releases ODROID-XU Development Board with a PowerVR SGX544MP3 GPU

Hardkernel have made a name for themselves within the open-source community by delivering high performance development boards at affordable prices. Today, the Korean company has just announced the new ODROID-XU platform boasting an Exynos 5 Octa processor – the same SoC found inside the Samsung Galaxy S4.

The Exynos 5410 inside the ODROID-XU board includes a PowerVR SGX544MP3 GPU clocked at around 600 MHz.

Get high performance and low cost with the ODROID-XU boards

The good news for developers is that we’ve worked closely with Hardkernel, enabling them to deliver a complete and fully capable graphics and compute platform by providing our latest PowerVR SGX OpenGL 2.1 and OpenCL 1.1 EP drivers for Linux as well as OpenGL ES 1.0/2.0 and Renderscript drivers for Android.

Furthermore, we’ve delivered all the resources they need to enable OpenCL and Renderscript on the Hardkernel ODROID-XU platform, opening up endless possibilities for developers to use GPU compute efficiently for realistic, mobile-specific applications such as image and video processing, camera vision or augmented reality, where keeping power consumption in check is vital.

Hardkernel have addressed this essential requirement for mobile graphics developers by including an on-board power measurement circuit for their ODROID-XU+E package. It connects to a smart power meter and allows users to monitor CPU, GPU and DRAM power consumption. This is a completely new feature for the ODROID family; by using the integrated power analysis tool, developers will reduce the need for repeated trials when debugging for power consumption and get the opportunity to enhance and optimize the performance of their GPU compute applications, and therefore keeping battery drain as low as possible.

In addition to OpenCL, our multicore PowerVR SGX544MP3 GPU implements much more than the baseline OpenGL ES 2.0 API – including a series of near-OpenGL ES 3.0 features – which allow developers to enhance visual effects in games, user interfaces or AR applications like no other GPU available today.

These APIs are meant to deliver some of the core functionality of OpenGL ES 3.0 to PowerVR Series5XT-based platforms, by offering essential features such as MRTs, occlusion queries, seamless cube maps, sampler access from vertex shaders, floating point textures, GLSL full-precision floating point and many more.

For Linux graphics and compute enthusiasts, we’ve worked with Hardkernel to deliver OpenGL 2.1 and OpenCL 1.1 EP which will allow ODROID-XU to run different flavors of the open-source popular operating system, including Ubuntu.

If that isn’t impressive enough, the full ODROID-XU package is priced at only $149 for early bird buyers, providing a much more affordable solution to developers who wish to have the industry’s leading platform in terms of features, performance and power consumption yet want a configurable and flexible solution.

ODROID-XU’s features and full specifications

The key features and specifications of the ODROID-XU development board include:

  • big.LITTLE processing based on the Cortex™-A15 and Cortex™-A7 quad core CPUs
  • PowerVR SGX544MP3 GPU (OpenGL ES 2.0, OpenGL ES 1.1, OpenCL 1.1 EP, Renderscript/Filterscript)
  • 2Gbyte LPDDR3 PoP (1600Mbps/pin, 2 x 32bit Bus)
  • USB 3.0 Host x 1, OTG x 1, USB 2.0 Host x 4
  • HDMI 1.4a output Type-D connector (Micro-HDMI)
  • eMMC 4.5 Flash Storage
  • Micro-SD socket
  • MIPI DSI for LCD display output
  • On-board Audio Codec
  • Fast 10/100 Ethernet LAN
  • WiFi, Bluetooth (Optional)

The Hardkernel ODROID-XU is capable of running Android and various Linux operating systems such as Ubuntu (support coming soon) and it’s available to purchase from the company’s store.

We are very excited to welcome Hardkernel to our ecosystem and ensure them easy access to drivers, our PowerVR Graphics SDK and other resources like our dedicated PowerVR Insider forum.

What are your first impressions on the ODROID-XU features and specifications? Are you thinking of picking one up? Leave us your feedback in the comment box below and follow us on Twitter (@ImaginationTech, @GPUCompute and @PowerVRInsider) for more news and announcements.

  • A few questions coming to my mind:
    -what are the limitations the GPU has compared to OpenCL 1.1 Full Profile?
    -how many compute units does the GPU have in OpenCL? actually, a list of basic OpenCL device properties would be helpful,
    -I read in the FAQ the board comes with Android 4.2.2, is an update to 4.3 planned?
    That’s all for now, thanks!

    • Hi,
      OpenCL 1.1 EP is a carefully chosen subset that defines certain optional and optimized elements for mobile and embedded applications; this is mainly to reduce power and area requirements.
      However, please remember that an OpenCL C program written for the embedded profile will work on any device that supports the full profile.
      A few differences:
      – 64-bit integers are optional (therefore avoid using long, ulong scalar and longn, ulongn vector data types in an OpenCL program that runs on mobile devices).
      – the mandated minimum single-precision floating point capability is CL_FP_ROUND_TO_NEAREST or CL_FP_ROUND_TO_ZERO for OpenCL EP vs. CL_FP_ROUND_TO_NEAREST or CL_FP_INF_NAN for OpenCL FP.
      We will provide the answer to your second question in our programming guidelines (soon to be released).
      For any questions regarding OS support, you will have to get in touch with Hardkernel.
      Best regards,

  • Great to hear about the OpenCL driver support. Just to clarify, the OpenCL drivers are for Linux? Second, wondering if there is an OpenCL programming/optimization guide for the 544MP?

    • Hi,
      We’ve delivered the Linux OpenCL DDK to Hardkernel and instructions to integrate OpenCL into Android. Therefore, you should have OpenCL up and running on Android for the ODROID-XU board.
      We’re working on finalizing the programming guidelines.
      Best regards,

      • Hi Alex,
        I am looking OpenCL driver support for Android, Can u share me any update if it is ready?
        Best Regards,
