Accelerating Matlab DSP Code on the GPU

Seth Benton March 25, 20102 comments

Intrigued by GPUs, I've spent a few days testing out Jacket, an interface that lets you accelerate MATLAB (my favorite, if frustrating language) on NVIDIA GPUs. It's definitely got some caveats. But it was really easy to accelerate my code. And the results were impressive. So I thought I'd put up a few simple DSP-related benchmarks I created and ran on my laptop (a Macbook Air with NVIDIA GeForce 9400M graphics card). The m-files for the two functions I benchmarked (2D FFT and 2D interpolation) can be...


OpenCV for DSP/GPU, MSDN equivalent for CCS, and more

A great business opportunity might await anyone brave enough to attempt a port of the OpenCV (Open Computer Vision) library to a DSP platform.  OpenCV is the lingua franca of "industrial grade" image processing, and it's my sense that the DSP imaging libraries out there pale in comparison to the breadth of features offered by OpenCV.  When writing my book for example, I fielded multiple inquiries about making an OpenCV port a centerpiece of the text.  Two problems arise, however.  First and foremost, the scale of this task is fairly large, and is probably why it...
