OpenCL <a href="http://en.wikipedia.org/wiki/OpenCL" rel="nofollow">http://en.wikipedia.org/wiki/OpenCL</a> okie, yes I think OpenCL needs a host processor to drive the GPU... doesn't work standalone. josh, I meant use the Maple to digitize EEG sensor data, then send to a laptop running an OpenCL program that uses a GPU to process the EEG digital data. The GPUs excel on decomposable problems like linear algebra and matrix operations. Do the signal processing in software where it is easier, and use the Maple for what it is really good at, interfacing with sensors. okie on "Better than a xilinx FPGA for oak why not a GPU opencl is a c library that allow" http://forums.leaflabs.com/topic.php?id=602#post-3309 Fri, 07 Jan 2011 01:24:59 +0000 okie 3309@http://forums.leaflabs.com/ I personally don't know much about exactly what you can do with raw GPUs and OpenCL or other languages and tools that are available regarding, particularly, low-level hardware type things like control over a GPU's pins and communication buses. Out of the box, do the available GPU development tools support using them as stand-alone processors and communicate to whatever you want or do they need to be connected to a processor running an operating system for which there are drivers provided, or what? I've forwarded these questions to someone who will know the answer. Of course, someone else at LeafLabs or on the forums may also know. I think I've slightly rephrased the question. soundcyst on "Better than a xilinx FPGA for oak why not a GPU opencl is a c library that allow" http://forums.leaflabs.com/topic.php?id=602#post-3307 Thu, 06 Jan 2011 19:41:57 +0000 soundcyst 3307@http://forums.leaflabs.com/ the TMS320C64c+ is a hardware core on the same die as the processor.. it's all one in one chip. and the best way to program it would just be with regular old c, with a compiler that takes advantage of the accelerator. and the DSP accelerator isn't the same thing as a parallelized GPU pipeline.. not a bad idea, but a bit half-baked. josheeg on "Better than a xilinx FPGA for oak why not a GPU opencl is a c library that allow" http://forums.leaflabs.com/topic.php?id=602#post-3306 Thu, 06 Jan 2011 18:54:08 +0000 josheeg 3306@http://forums.leaflabs.com/ Better than a xilinx FPGA for oak why not a GPU opencl is a c library that allowsa a GPU to be programmed in c. So maby the maple can load video or EEG or EMG data and a GPU like the one mentioned in the beagle board be used on the oak but one easier to solder. TQFP maby... The OMAP3530 includes an HD-video capable TMS320C64x+ DSP for accelerated video and audio decoding, and an OpenGL ES 2.0 capable 2D/3D GPU. Video outputs can be provided by the on-board S-video or DVI-D (HDMI connector) outputs.
