opencl pipe question

I would like to use pipe to store the data produced from kernel 1 and use it in kernel 2.

The NDRange setting in kernel 1 is

WorkSize[3] = {56, 56, 96}

WorkGroupSize[3] = {14, 14, 1}

kernel 1 will produce 56*56*96 data and be used in kernel 2

Each work group in kernel 1 produce 14*14*1 data.

can it realized in opencl pipe?

Thanks,

Matt

    It certainly can. You should just pay extra attention to ordering of work-items and how data is written to and read from the channel. This is described in Section 1.6.4.3 of the Intel FPGA SDK for OpenCL Programming Guide.
