7.16. Forcing Ring Interconnect for Global Memory (-global-ring)

The Intel® FPGA SDK for OpenCL™ Offline Compiler attempts to choose an optimal global memory interconnect topology based on various characteristics of the design.

To override the compiler's choice and force a ring topology, use the -global-ring option in your aoc command. This can improve your kernel fmax.

Example: aoc -global-ring <your_kernel_filename>.cl
