OpenCL compliant DSP

On the Khronos website, OpenCL is said to be open to DSP. But when I look on the website of DSP making companies, like Texas Instrument, Freescale, NXP or Analog Devices, I can't find any mention about OpenCL.

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 provides a uniform programming environment for software developers to write efficient, portable code for high-performance compute servers, desktop computer systems and handheld devices using a diverse mix of multi-core CPUs, GPUs, Cell-type architectures and other parallel processors such as DSPs"

So I think it would be interesting to know if it's true, if DSPs, which are particulary suited for some complex calculations, can really be programmed using OpenCL.

As far as i know OpenCL is supported by some GPU and CPU. Never heard about DSP. – Andrey

The OpenCL spec seems to support using a chip that has one or more programmable GPU shader cores as an expensive DSP. It does not appear that the spec makes many allowances for DSP chips that were not designed to support being used as a programmable GPU shader in a graphics pipeline.

I finally found one: The SNU-Samsung OpenCL Framework is able to use Texas Instrument C64x DSPs. More infos here:
