Thanks for your response.
I think that the channel extension itself is not supported for SoC platforms. Because even the simple kernel like the one below is not working. It compiles fine. However, the commands will not finish at all. I am using Arria 10 SoC platform with Quartus Pro 16.1. Please help to clarify. I tried posting is forum but I was asked to contact Altera directly. Please suggest / redirect this request accordingly.
------------------This is the kernel I am using-----------------------------
#pragma OPENCL_EXTENSION cl_altera_channels : enable
channel int c0;
__kernel void producer() {
for(int i=0; i < 10; i++) {
write_channel_altera(c0, i);
printf("Producer : Writing %d into Channel\n", i);
}
}
__kernel void consumer( __global uint * restrict dst ) {
for(int i=0; i < 5; i++) {
dst
= read_channel_altera(c0);
printf("consumer : read %d from channel\n", dst);
}
}
