Results of simple BRAM to user space throughput testing.
Posted: Tue Mar 24, 2015 4:36 pm
Hi All,
I thought I would share some early results, using the Parallella with a simple AXI BRAM controller.
44MBytes/s per thread for 4k page size transfers. I Only tested with 2 threads, but was able to get an aggregate of 88MBytes/s using mmap and memcpy to user space. Right now I have a single 8k BRAM attached.
I hope this helps someone else.
Best Regards, Mike
