7 years agoUnexpected low Kernel Clock Frequency
I'm working on an OpenCL kernel targeting a Cyclone V SoC that should process a continuous real-time sample stream at a sample rate of 16 MHz, which requires a certain kernel clock frequency so that ...

You seem to be using a custom-made BSP with multiple custom I/O channels; your critical path very likely lies in your BSP. You can try compiling an empty OpenCL kernel to see what operating frequency you will get. If what you get is still in the same range, then your critical path is in the BSP and you should optimize your BSP.

7 years agoHi,
Thanks @Hamid Reza Zohouri.
After I compare both edition in Quartus, I found that the fmax report can be view directly in 19.x GUI while you still can view fmax in the loop analysis report as in figure 53 in document as link: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/opencl-sdk/ug-aoclstd-best-practices-guide.pdf
Thanks
