The following technologies are assessed:\n\n* OpenCL (projects are prefixed with \"Cl\")\n* OpenGL ES 2.0 shaders (projects are prefixed with \"Gl\")\n* Android RenderScript (projects are prefixed with \"Rs\")\n\nFor details and results, please refer to the [project page on my website](http://mkonrad.net/projects/mastersthesis_mobile_gpgpu.html).\n\nUnfortunately, the code is not very well documented because of the general time pressure during writing a master's thesis. Nevertheless, I hope that this helps people who want to get started with GPGPU on mobile devices.\n\nThe code has been tested with a Nexus 10 running Android 4.2.1. Please note that OpenCL support is not available on most devices (see p. 20 of my master's thesis) and requires manual setup (see [this post](http://sweetpea.tentacle.net/blog/opencl-on-nexus-4/) and [that post](http://www.openclblog.com/2013/02/opencl-on-nexus-10-part-1.html)).\n\n# Available Prototypes\n\n* *ClAudio* -- OpenCL-driven simple real-time sound synthesis\n* *ClImageProc* -- OpenCL-driven image convolution and Hough transform with kernel generator\n* *CvMarkerDetect* -- Marker based augmented reality prototype based on OpenCV and partly accelerated on the GPU via OpenGL ES 2.0 shaders\n* *GlImageProc* -- OpenGL ES 2.0 shader driven image convolution with kernel generator (uses Java API)\n* *GlImageProcNative* -- OpenGL ES 2.0 shader driven image convolution, thresholding and Parallel Coordinate space based Hough transform (uses NDK API)\n* *RsImageProc* -- Android RenderScript driven image convolution (limited functionality, crashes)\n\n# LICENSE\n\nLicensed under BSD 2-Clause license.
