Question about sequence load form global memory and parallel load from global memory ????

hi HRZ: I need some help ! In my project (single kernel ), i am trying to load data form global memory by sequence(that is serial sequence) to local memory (inner of FPGA),.i declaration many local...

Thanks for your reply!

Yes in the second case, it create cached LSU use RAMs, it parallel load from the GM(global memory). But i want load it in serial (first case), that is 1....256 to the first local buffer(use RAMs), 257...512 to the second buffer(use RAMs)..............., my first case seems failed! how can i do that ?????

You do not need to concern yourself whether the compiler uses Block RAMs or not. The compiler might optimize your memory accesses in a way that they use registers instead of Block RAMs, which is better since it will use less resources. As long as the global memory accesses look the way you expect them to in the report, it will be fine.
