kernel discussion is based on the
information provided in the C/C++ Kernels topic. The same
programming techniques for accelerating the performance of a kernel apply to both C/C++ and
OpenCL kernels. However, the OpenCL kernel uses the
__attribute syntax in
place of pragmas. For details of the available attributes, refer to OpenCL Attributes.
The following code examples show some of the elements of an OpenCL kernel for the Vitis™ application acceleration development flow. This is not intended to be a primer on OpenCL or kernel development, but to merely highlight some of the key difference between OpenCL and C/C++ kernels.
