SYCL (pronounced ‘sickle’) is a royalty-free, cross-platform abstraction layer that builds on the underlying concepts, portability and efficiency of OpenCL that enables code for heterogeneous processors to be written in a “single-source” style using completely standard C++. SYCL is developed by the Khronos group.

SYCL single-source programming enables the host and kernel code for an application to be contained in the same source file, in a type-safe way and with the simplicity of a cross-platform asynchronous task graph. SYCL includes templates and generic lambda functions to enable higher-level application software to be cleanly coded with optimized acceleration of kernel code across the extensive range of shipping OpenCL 1.2 implementations.

Developers program at a higher level than OpenCL C or C++, but always have access to lower-level code through seamless integration with OpenCL, C/C++ libraries, and frameworks such as OpenCV™ or OpenMP™.

Implementations of SYCL include ComputeCpp and triSYCL.

Tensorflow with sycl with fpga acceleration

So I need to have some form of low latency hardware acceleration for Tensorflow inferencing on a raspberry-pi. I looked into using leflow but it cannot support large tensorflow models on small FPGAs. I have figured out how to build tensorflow from…

How is control flow extracted from a SYCL kernel?

Using SYCL to run code on any OpenCL device doesn't require a custom compiler, as everything is done in a library (full of template magic), and a standard GCC/Clang will do just fine. Is this correct? (Especially in the case of triSYCL, which I'm…
