DSP OpenCL libraries. OpenCL™ (Open Computing Language) OpenCL is a framework for expressing programs where parallel computation is dispatched across heterogeneous devices.It is an open, royalty-free standard maintained by the technology consortium Khronos Group. On a heterogeneous device, OpenCL views one of the programmable cores as a host and the other …

Our first simplest approach involved having about 200 threads (one per channel) on the ARM host sharing a single OpenCL context and command queue. Every 20ms, each host thread simply writes its real-time audio data to an OpenCL buffer and enqueues a kernel task to the command queue for DSP to do the complex algorithm processing.
signal processing - OpenCL compliant DSP - Stack Overflow
https://stackoverflow.com/questions/5445597/opencl-compliant-dsp
So does anyone knows if a OpenCL compliant DSP exists? Edit: As this question seems surprising, I add the reason why I asked it. From the khronos.org page: "OpenCL 1.0 at a glance. OpenCL (Open Computing Language) is the first open, royalty-free standard for general-purpose parallel programming of heterogeneous systems.
OpenCL GPU Audio - Stack Overflow
https://stackoverflow.com/questions/20080892/opencl-gpu-audio
DSP operations on modern CPUs with vector processing units (SSE on x86/x64 or NEON on ARM) are already pretty cheap if exploited properly. This is particularly the case with filters, convolution, FFT and so on - which are fundamentally stream-based operations. ...

Besides, OpenCL code is inherently easier to create, read, and understand (and thus maintain) than any HDL or DSP assembly language code. OpenCL is not a perfect solution, however. There are significant shortcomings that have the potential to either limit its adoption for FPGAs and DSPs, or completely kill it. The first problem is the host ...

OpenCL is an open standard while CUDA is tied to NVIDIA GPUs. Fortunately, NVIDIA also supports OpenCL. With OpenCL, you are not tied to a proprietary architecture that is inflexible and difficult to port. Ideally, you will want to program in a high-level language. ... Audio DSP programming is inherently parallel and one can’t really have ...

Use the most efficient data type on the DSP¶. Pick the most efficient data type for an application. E.g., if it is sufficient, prefer the ‘char’ type to represent a 8-bit data over using a ‘float’ type. This could potentially have a significant impact because: It makes more efficient use of available data bandwidth.
