We are trying to quickly "compare" the resource usage of OpenCL and Bluespec implementations of the same design.The Bluespec implementation doesn't have PCI-E and external memory.
AOC reports total resource usage as shown below. I am thinking of removing "Global_resources" (and possibly "LSU_resources") from OpenCL's resource usage to make the comparison fair. I am assuming that "Global_resources "and "LSU_resources" approximate the cost of using PCI-E and external memory. Is this a sensible approach?
Total: LEs = 62637 FFs = 99198 RAMs = 575 DSPs = 0
Global_resources: LEs = 8779 FFs = 12545 RAMs = 78 DSPs = 0
Const_resources: LEs = 0 FFs = 0 RAMs = 0 DSPs = 0
LSU_resources: LEs = 6802 FFs = 12446 RAMs = 83 DSPs = 0
FP_resources: LEs = 0 FFs = 0 RAMs = 0 DSPs = 0
Local_mem_resources: LEs = 1330 FFs = 4352 RAMs = 28 DSPs = 0
Reg_State_resources: LEs = 1133 FFs = 10610 RAMs = 0 DSPs = 0
RAM_State_resources: LEs = 2899 FFs = 2425 RAMs = 85 DSPs = 0
MrgBr_State_resources: LEs = 0 FFs = 2844 RAMs = 0 DSPs = 0
Other_State_resources: LEs = 908 FFs = 820 RAMs = 18 DSPs = 0
Other_resources: LEs = 1710 FFs = 1685 RAMs = 0 DSPs = 0
------------
LEs: 13.3429 %
FFs: 10.5656 %
RAMs: 22.4609 %
DSPs: 0 %
Util: 22.9721 %
