How to infer BRAM fan-out

I am doing an OpenCL project of vector multiplication of VecA (M * 1) and VecB (1 * N) which produces a matrix MatC (M * N). I want to use a fan-out design which can support a 2-D processing engine ...

Hi, I tried the systolic array and it takes massive amount of BRAM and registesr (mostly for control overhead) which causes my design to be severely memory-bounded. But if I do the fan-out design, the way I unroll the loop cannot work out, it produces wrong output in hardware run. Do you have any idea how the loops should be unrolled?
