Has anyone thought about something like Apple's Core Image for signal
processing? Core Image lets you express image filters in a C-like filter
language (a subset of GLSL). You chain a set of filters together to achieve the
desired effect and then at runtime Core Image uses an LLVM complier to ge
I have a feeling -- from working with OpenCL for a while now (but, not in GNU
Radio yet), watching profiling timing information (how long it takes to move
data around, how long kernels take to get queued and executed) -- that what
folks here have written seems mostly true: there is -significant-

Greetings,
I've begun to look into accelerating GNURadio applications with Nvidia CUDA
GPU's
and have scanned through the archives of the discussion list. I had two
questions on the topic:
1. Is the CUDA-GNURadio port done by Martin DvH circa 2008 still
available and runnable? All links I've s
