Description
This rule checks whether the device is using high bandwidth memory.
Explanation
To optimize performance,Xilinx recommends using high-bandwidth memory (HBM) on supported devices. HBM offers benefits in performance, power, and footprint over traditional DDR memory technology.Recommendation
To take advantage of HBM, assign CL memory buffers to HBM in the host code
and specify corresponding port mapping using the
--sp
v++ linker option:
v++ -l --sp <compute_unit_name>.<kernel_interface_name>:HBM[0:15]
